IMO, this series to me highlights the weakness of the offense in terms of power and XBA power in the lineup.
Brewers currently give up the 2nd most HRS in the NL with only the Rockies giving up more. So when the pitching gives up runs it usually is via the HR route. This hurts because the Brewers are 10th in NL in hitting HR's, so we are always going to be out slugged by the opposition. Every other team that is in the playoffs that the Brewers are most likely to face in the NL hits more HR's than the Crew.
Brewers get on base, 2nd in the NL(way above league average) but our lack of XBA production in the lineup cancels that out. Brewers are 8th in the NL in SLG(slightly above league average), 10th in 2B's(below league average), and 8th in 3B's(at league average), 6th in K's(above league average). These areas also negates the main weapon of speed on the roster.
So the Crew needs to get 2-3 hits an inning coupled with BB to generate runs. Most of our lineup is of the punch and judy type. Slap the ball on the ground and hope the speed generates a hit. This isn't a surprise, as this is the type of player the Brewers FO target not only at the MLB level but also in the MILB.
This works over a 162 game schedule, as indicated that we are 5th in the NL runs and R/G and 4th in AVG, but in a playoff situation where you are always facing the best SP and Bullpen in a series will, like in years past, be a tough formula for winning. Especially, when one swing of the bat against the opposition can put you down by 2-3 runs immediately. Preface, I said tough not impossible. Anything can happen in a short series.
Adding more more SLG to the lineup I think coupled with SP that can save the bullpen is necessary not only for this year but for the next window of contention.
