Hell, I'd say Marmol has been more valuable than Theriot and he's only a reliever who wasn't even in the bigs in April. Marmol has a WARP3 of 4.3, while Theriot has a 3.7... and that doesn't even account for Marmol's much higher leverage. WARP for pitchers is leverage adjusted. Well sorta. It's a [expletive] way but it is. BP really has a disaster on their hands with WARP for pitchers. Its too bad theyre too dumb to know it oh and in addition, Marmol's leverage isnt all that high for a reliever. It really isnt. Thats Lous fault more than anything. I just looked it up. 53rd in the NL. Seems like it should be a lot higher. Correct me if I'm wrong (and I very well could be since I don't know a ton about Leverage Index), but isn't Leverage Index a situational stat, based on the various game state (inning, score, men on base, and outs). Its NOT based on who the pitcher is facing, right? So, while Dempster can pitch in the 9th inning of a one run game against the 7th, 8th, and whoever is left to pinch hit, Marmol could have pitched the 7th inning of a game with the same score against the 1st, 2nd, and 3rd hitters and would have a much lower leverage index, correct? As I'm writing this, I'm realizing that I'm kinda getting away from the main point of LI, but it would be cool to incorporate the OPS (or since its a Tangotiger stat, wOBA) of the batters the pitcher is facing. That would provide a more indepth picture as to how important the situation is. The difference between opponents' OPS for Dempster and Marmol is negligible.
