Brewers" starting pitching is a strength of the team. They have two of the top starters in the league for the first half of the season. The guys behind them are all quality arms as well. Yes, other than Woodruff, the experience is a little light but these guys aren't kids either. Gasser and Drohan are both 27. Sproat will be 26 in September and Henderson is 24. I'm pretty confident that one or two of those guys will emerge as legit playoff contributors. They're all close right now when healthy.
The only starting pitching move that makes sense would be to see if they can get Skubal. That's the move that makes them a World Series favorite and the Brewers have never had a deeper system than they have right now to make it happen. 56 years is long enough. Go for the gold.
As for 3rd base, there's not a guy out there that moves the needle for me. Maybe they bring up Andrew Fischer in September. But I'll take the defense Ortiz provides and so will the pitching staff. Rengifo was acquired to provide some pop at third. How did that work out?
The bullpen needs a little help, but a healthy Hall and/or Koenig might be enough.
