What is not the same about a RH pitcher getting a LH hitter out? All I'm saying is you have to look at both the pitcher's splits and the hitter's splits I did some quick back of the envelope math and this is what I found: LH hitter vs LH pitcher (all MLB w/minimum 100 ab) BA .256 OBP .320 SLG .482 OPS .802 LH hitter vs RH pitcher (all MLB w/minimum 100 ab) BA .276 OBP .352 SLG .552 OPS .905 So, if I understand your position correctly, you would rather have a LH pitcher face a LH hitter in every key situation late in the game? Then why have a RH closer? Other teams will surely send LH bats up there, right? I have to disagree with your premise that just because in general LH hitters have better splits vs RH pitchers, you would automatically prefer the reverse situation. Taking individuals numbers, more importantly than that, taking their recent success into consideration, and then I make the call. I've seen effective relievers removed too many times to see the matchup guy blow the inning or game. And I've seen situations where effective relievers blow the inning or game with an obvious match-up guy standing in the pen ready to go. Having said that I do agree with what you're saying for the most part, of course you have to look at each situation individually. To answer your first question yes I believe that most of the time later in the game you'd use a LOOGY to face a tough LH hitter in a close game. I'm not talking about bringing in a LH to face Michael Borne in a two run game with two outs in the 8th. I'm talking tight games with guys like Bruce, Fielder, McLouth, LaRoche, Ankiel, Kennedy, Either, Delgado, Loney, Howard, S. Drew, - guys with lopsided splits. Obviously if the reliever is a lights-out type of guy there's no reason to bring in a LOOGY. This is the answer to your 2nd question - no I generally wouldn't play match-ups in a 9th inning save situation with the closer in the game. The closer should be your 1st or 2nd best reliever and trustworthy enough to be given a longer leash. There is only one guy in the cubs bullpen (at the moment) that fits that bill. But if it's late in a close game (7-8th inning) and Prince Fielder is stepping up to the plate I'd elect to use Will Ohman (for example) over the Shark. I think if you're going to go with a 12 man bullpen there should be room for a specialist from both sides. I hope not to see Heilman facing too many LH this season and I hoped to the cubs landed someone like Brian Shouse.
