This what Brewers did last year: vs. RH: .252/.316/.439/.755 vs. LH: .288/.360/.499/.860 This year, not including today: vs. RH: .230/.278/.363/.641 vs. LH: .300/.363/.543/.906 Not only do I not expect the current split to continue (I think we all agree on that, though), I don't think we should expect even the same platoon split as last year (a .105 OPS split is HUGE). Unless we think that the team is comprised of players that all have extreme platoon splits , I don't see how we should expect a repeat of last year. And really, we have no way of knowing what players have unusually large, expected platoon splits, anyway. The approximate average platoon split for a RH handed hitter from 2002 - 2004 (from "The Book"): OBP: .014 SLG: .023 OPS: .037 As the Book points out, there is some decent variation for batter to batter in their expected split. Some RH batters do struggle a lot more against same handed pithers than others. But a RH batter needs a very large sample against lefties before you can even identify which ones they are (around 2,000 PA!). Kendall is pretty close to that threshold (he has 1631 PA against lefties, .038 OPS split.. league average). Cameron is close as well (1572 PA, .076 OPS split, which has to be regressed to the mean somewhat). No other regular is even close. As a team, we are forced to expect a league average platoon split. There just isn't enough evidence to the contrary. Is it going to hurt the Brewers more than an average team? Yes. But the average good right handed hitter is typically still expected to be pretty decent against a right handed pitcher. They are going to lose their share of games when a Rh pitcher is on the mound but it's most likely not going to be a big deal overall.
