    Every baseball roster is at least a little lopsided. The existence of a “Goldilocks” team where every position contributes evenly is about as possible as a Mariners World Series appearance in the next decade. On the bright side, this uneven distribution of talent on a major league squad is exactly what makes trade deadline conversations so entertaining. For a team as competitive as the Brewers, the discussion should largely be framed on what sort of upgrades they should prioritize before making the final postseason push.

    To start, let’s make this process as empirical as possible. First, we’ll look at the high-level offensive and defensive statistics of each position and how those numbers compare to the rest of the league. Using this information, we can gauge where the most glaring holes in the lineup are, if any exist. 

    Position

    OPS

    Defensive Runs Saved

    Catcher

    .722 (11th)

    2 (10th)

    First base

    .793 (9th)

    0 (16th)

    Second base

    .731 (7th)

    6 (6th)

    Third base

    .619 (26th)

    6 (4th)

    Shortstop

    .546 (29th)

    -7 (27th)

    Left field

    .756 (12th)

    2 (14th)

    Center field

    .738 (10th)

    -6 (23rd)

    Right field

    .728 (16th)

    7 (8th)

    This simple table makes a few things quite apparent. The outfield is well-rounded, except for some lackluster fielding work by Jackson Chourio and Sal Frelick when they have to play center field. Brice Turang is still one of the best second basemen in baseball, Rhys Hoskins has remained a solid contributor at the plate when healthy, and William Contreras is still a valuable backstop, even given his offensive regression. These positions are by no means perfect, and most are good, not great, but they aren’t problematic enough to be high priorities for the front office this year. 

    While most positions are above average with either the bat or the glove, one position is clearly below average in both: shortstop. The struggles of Joey Ortiz have been apparent for the entire season, and despite seemingly coming back in June with a .748 OPS over 90 plate appearances, his first 30 plate appearances of July culminated in just a .578 OPS. This mark is still somehow better than the .570 OPS he has for the entire season. 

    His struggles at the plate seem to be creeping into his defensive effectiveness as well. His range is still top-notch, but his eight errors and -8 Defensive Runs Saved paint a grim picture. There seems to be a lack of urgency and focus overall, something the Brewers are clearly aware of. Still, it may not be enough to push them to pursue a new shortstop. Ortiz has already shown that he can hang at the major league level when things are clicking; he has plenty of team control left, and there just aren’t very many viable shortstop targets available. I suppose Eugenio Suárez played a bit of shortstop for the Reds four years ago, and I bet Zac Gallen was an excellent shortstop in Little League. However, realistically, it’d be challenging to find a suitable upgrade. 

    There are slight upgrades that can be made at other positions, such as right field and third base, but one quality the lineup is clearly missing is power. The Brewers are slugging just .383 as a team, 22nd in MLB. Getting a power bat, perhaps at third base, could be what Milwaukee’s offense has been missing. The aforementioned Eugenio Suárez is one of the most enticing options here as he has been having a career year in Arizona, posting a 142 OPS+ and leading the National League in RBIs with 78. Ryan McMahon and Ramón Urías are two other options, but both are similar to Caleb Durbin in that they’re all defensive assets and offensive liabilities. However, Durbin has turned things around recently and is now sitting at a 103 OPS+, far better than the marks posted by McMahon and Urías, so expect him to keep his spot if Suárez isn’t available. 

    When it comes to pitching, the Brewers are actually in pretty good shape. Overall, Milwaukee has a combined 3.66 ERA, which is tied for 7th in MLB. However, separating the numbers by role highlights some potentially glaring issues.

     

    ERA

    WHIP

    Innings Pitched

    Starters

    3.39 (5th)

    1.24 (13th)

    477 ⅔ (25th)

    Relievers

    4.00 (18th)

    1.26 (10th)

    375 ⅔ (5th)

    The bullpen is on the verge of being overworked. Of the four teams with more bullpen innings than the Brewers, three are non-contenders (White Sox, Marlins, Athletics), and the other is the Dodgers, whose 60-day injured list would be a top-five rotation in baseball if they were healthy. 

    Milwaukee’s rotation is rich in talent, but other than Freddy Peralta, none are really innings eaters. Brandon Woodruff has made just two starts since returning from his long layoff, Jacob Misiorowski is a true rookie, Jose Quintana sometimes finds himself laboring to get through five innings, and Quinn Priester is still ramping up to higher volume. It puts Milwaukee in a tricky position because there’s just no room for a back-of-the-rotation arm that would give you six to seven gutsy innings every five days and reduce the bullpen’s workload. The Brewers have clearly chosen to prioritize quality over quantity, which should dictate how they plan on constructing the bullpen in the second half. 

    The two hidden gems of the bullpen are Aaron Ashby and DL Hall. Milwaukee has recently experienced great success using long relievers (shoutout my guy, Bryse Wilson), and having two quality arms capable of covering multiple innings of relief is a primary reason the pitching staff has made it this far. Of course, more is always better, so if they so choose, the front office could look at another durable arm. There’s hardly a need for a flashy, lights-out, one-inning closer like Emmanuel Clase or Jhoan Duran, but someone capable of getting more than three outs like Jake Bird could be a sneaky upgrade.

    As is, the Brewers have a solid roster. It’s the reason that they find themselves within striking distance of the Chicago Cubs in the NL Central despite a rocky start to the year. However, they have a relatively high strength of remaining schedule with a series against the Dodgers ringing in the latter half of the season, so they can’t afford to rest on their laurels just yet. Furthermore, making it to the postseason is one thing. Milwaukee’s faithful are all too familiar with the feeling of a first-round exit. If the team wants a real chance at making a meaningful run, the seemingly small upgrades at this year’s deadline could end up making big differences come October.

    I think this analysis is missing a couple of things. One is to use more than one defensive metric when it comes to small sample sizes like we're dealing with here. DRS thinks Ortiz is one of the worst SS getting regular playing time in the league. FRV thinks he's above average, top 10 even. DRP thinks he's slightly below average. Which one is "right" is hard to know, but having watched most games this year I don't buy that he's a bad defensive SS. I don't think the Brewers internal defensive metrics do so either. 

    Another thing to consider is the SP vs RP workload and the use of openers. 5 Quinn Priester "bulk pitcher" relief appearances (27 IP) are, from a workload perspective, SP innings. This would move the team about 5 spots in the ranking. And further looking at the pitchers currently on the active rosters, the current crop of Brewers relievers have pitched a below average amount of innings. 

    The real issue is more that some specific relievers, Uribe in particular, have pitched a lot. So bringing in another late inning option to be able to avoid needing to use Uribe or Mears sometimes would be helpful. But just looking at the macro level of total IP is a bit too simplistic.

    As we entered the offseason, I wanted Suarez as a RHH bat to replace Adames’ offense, but I didn’t realize that we only had $4m to spend.

    At this point, I’d still target a solid position player. Maybe McMahon can turns things around by being in a winning environment a la Andrew Vaughn. That could also protect our offense a bit in the extraordinarily unlikely event that Yelich or Frelick are out during the home stretch.

    I also figure we need a reliever after relying so much on Mears, Uribe, Koenig and Megill. It’s just that every deadline reliever trade post-Pomeranz seems to blow up on us.

    Willi Castro for Monasterio, and Ryan O'Hearn for Bauers. Those moves add slugging, versatility and experience without messing with the current team's success. 

    I'm 1000% on board with O'Hearn. 

    The Castro move could be sneaky good too. I think I often underrate the value of those edge pieces on the roster, but with an impending FA like Castro, the cost might be really low to give Murph a lot of versatility.

    I’m fully on board the Willi Castro train. 
     

    id like Ohearn too, but that might be getting a little too optimistic. 
     

    in my head I’m hoping for Castro and a guy like Nathaniel Lowe.

    DRS is definitely a pretty opaque metric but I think once you take a look at the deeper numbers, it adds a little more color. If you're super bored while having to spend time with your in-laws or that nephew you resent, Fielding Bible has a brief description of the DRS calculation as well as how each underlying piece is calculated.

    The biggest area that drags down Ortiz's DRS is rPM (AKA Plus Minus Runs Saved) which, according to FanGraphs, evaluates the fielder’s range and ability to convert a batted ball to an out. More specifically, each batted ball event is compared to similar batted balls based on exit velocity and horizontal launch angle to calculate a likelihood that it is converted to an out. The less likely the play goes for an out, the more "credit" the fielder receives for making the play. The more likely the play goes for an out, the more the fielder is punished for not making an out. More can be found at the top of this article.

    Of course, other statistics like Run Value and Expected Batting Average share a similar weakness in that we can only go so deep as external viewers. I wish I could see all of the batted ball events that punished Joey Ortiz the most but until then, we only have the metric to go off of. Furthermore, it is noted that DRS isn't a great metric over a single season since defense varies quite a bit.

    One might point out that Ortiz has a top decile OAA which highlights the difference in the two metrics. Outs Above Average only measures range but doesn't penalize players for making errors or botching double plays. OAA is a narrower measurement of fielding while DRS is more of a composite figure. Because FRV is based heavily on OAA and arm strength, it paints a similar picture of being above average that doesn't seem to align with DRS.

    Agreed, unless he's getting penalized for the errors (I'm ignorant on how DRS is calculated). He absolutely is a better defensive shortstop than that.

    To me, this is the key differentiator. If we look at fielding percentage, Ortiz's number of .975 places him 18th out of 25 qualified shortstops. It still doesn't explain why the Brewers have insisted on giving him consistent playing time at the role and how their internal metrics may differ. Maybe they think he can figure things out, maybe they insist he's the next Derek Jeter. Either way, the statistics that we have access to paint a suboptimal picture, even if it isn't the entire story.

    I was thinking the same thing while reading the post. Add in that every reliever currently in the roster has been pretty good. We’ve ditched Payamps, Alexander, Thomas, Peguero, Rodriguez,  etc who were kinda duds. 
     

    I think once Cortes comes back, we will be in a 6 man rotation. So that will bring us down to a 7 man pen until September so we need Murphy to trust DL Hall more. We need him pitching more than once per week. I’m not really sure where they’d fit an outside reliever onto the 26 man roster. 

    Ortiz was a glove first prospect out of the gate.

    He's been a plus defender by scouting reports and eye test.

    At third he was +9 DRS and +9 FRV.

    At SS he is -7 DRS and +4 FRV.

    I barely look at UZR anymore but even they have Ortiz plus at both 3B (+4.3) and SS (+1.4) for his career.

    This year's DRS at SS is looking like the outlier to me.

    "Willi Castro for Monasterio, and Ryan O'Hearn for Bauers. Those moves add slugging, versatility and experience without messing with the current team's success."

    I'm sorry and do not wanna sound rude.  However, the suggested trade above would have the respective GM's for the Twins and Orioles would have them saying, "Ok, these are the throw in players obviously." Now let's talk the REAL negotiations.  Castro and especially O'hearn are going to cost you MUCH, more!  

    Honestly, this would get both GM's fired quicker than you can blink.  If you look on accepted sites like MLBTradeRumors, you'd know that Castro and especially O'Hearn are highly sought players and Monasterio/Bauers doesn't come remotely close.

    So did Van Gogh, but he was still one helluva artist.

    I am not buying that PARTICULAR picture being painted of Ortiz at SS. He's an elite defensive SS. I think the Brewers have two guys who would be well above average Shortstops, Turang and Ortiz. 

    The hitting is the issue, I don't agree it's the defense.

    Just gonna ask again to whoever may know and hopefully someone will and they'll see it, but how was Collins at 2nd Base?

    Because we have a stud SS at 2B. He'd won the job. He got a dead arm in STing and they went with Ortiz. I don't think it's a big deal. If you can find a LF(and Collins can play an above average defensive 2B) slide him over. 

    If you can find a 3B, Durbin can play some 2B. 
    If you can trade for Kentel Marte(you can't, but... hypothetically) you have again solved your problems.

    Doesn't need to be a need, you have 3 elite power arms in your BP on TOP of Ashby, Mears, Koenig, and everyone else, you're just shortening the game ANOTHER inning. 

    Jhoan Duran? I'd take him in a heartbeat...or Clause or Bautista. I loved the Royals approach. Get 3 dominant relievers and put pressure on a team to get a lead before the 7th inning comes. 

    But the cost would be prohibitive. Bird would be...alright.

    We're usually picking up a guy who hasn't been very good or has all these warts and hoping we can fix him immediately. 

    And they've been bad, but we're not giving up much. Reece Olson hurt...and I hated that and I hated Kelly for Bush at the time though I did like Bush. 

    But a pitcher like Soroka could be a great addition...IMO. Stuff plays up out of the pen and he's not QO quality, but he could have a big impact on a BP I think.

    And herein lies the weakness for DRS, particularly for infielders.

    I think it's safe to assume that the lower the exit velocity, the more likely a batted ball is going to be an out statistically.  You don't need to look any further than the last out of the game last night to know that isn't true, particularly for infielders.  In fact, it may be more of a parabola for exit velocity and likelihood of making an out for infielders.

    Last night Ortiz didn't have to go to his left or right (range) to make the play - he had to charge it because it was so softly hit.  Charging and bare-handing a ball to make an accurate throw to 1B is very, very difficult.  If a ball is hit too softly (low exit velocity), an infielder has very little time to make the play because they have to charge the ball before throwing it.

    Horizontal launch angle is also flawed because it depends on where the infielder is positioned.  On one play an infielder may be shaded towards the bag or the hole depending on the pitcher (LHP vs RHP) or baserunner (holding a runner on, threat of a SB).  Last night, the horizontal launch angle would have showed that it was hit right at Ortiz, and likely statistically a high probability of being an out.  Anyone who watched knows that was far from the case.

    My guess is that the last play of the game, based on exit velocity and horizontal launch angle, would have showed a very high probability of making an out.  The reality is that it was an incredibly difficult play that had a high probability of the runner getting on base.

    I think it's a similar situation to last year with with Adames... 

    They just talked about on the broadcast how there were communication issues between Durbin and Ortiz and how there were a couple balls Durbin could get to that he didn't because he knew Ortiz had an easier player.

    I don't think it's a coincidence that Chapman is one of the top defensive 3B as was Ortiz last year. I think that can hurt a good SS's defensive metrics. The rule that you take "every ball you can get to," is dumb. There was a play, Ortiz was shaded toward the hole, hard hit GB and Durbin pulled upon it, easy out. It's not as easy an out with Durbin having all his momentum taking him toward RF and having to turn and throw with no power in his legs. 

    I'm  far more...confident in this theory with Ortiz than Adames, but I think it applied to both.

    Generally followed by doing just that.... if you thought someone was actually saying that'd be the cost to acquire those two players.

    I think this is a valid concern but I believe the out likelihood of each batted ball is compared to other similar batted balls, so assuming softly hit ground balls that must be charged have been difficult to convert to outs for other infielders, it would be reflected into the out probability.

    Another good point. Fielder positioning is also acknowledged as a weakness of rPM per BIS:

    Quote

    The Range & Positioning system doesn’t know why the player made the play; it just knows that he did (or that he didn’t). As a result, the best plays according to the Range & Positioning System aren’t always flashy Web Gem nominees. As with anything else, the best defensive players can make the hard plays look easy. 

    So as with pretty much every statistic in baseball, interpret each number as you will but I wouldn't rely on it to define your perspective entirely.

    My perspective on Joey Ortiz is broadly that it has been a worse year than last year and of all the positions in the lineup, shortstop seems like one of the biggest holes right now. That said, I still think he has great upside and it's not like there's an easy and obvious upgrade out there so I don't think there's as much urgency to get rid of him.

    Here is a clearer version of that sentence: Willi Castro would replace Andruw Monasterio on the roster, and Ryan O'Hearn would replace Jake Bauers on the roster. It didn't cross my mind that the players would be traded for the players they would replace on the roster, My intent was to show that they would be supplemental additions.
