Ron, not to be insulting but I don't know what game you're referring to there. The one I was referring to in the post that the other guys replied to was Saturday's game, in which Hafner's 11th-inning run-scoring fielder's choice groundout turned bases loaded, one out, tie game into first and third, two out, up by a run: - J. Barfield singled to left - M. Rouse sacrificed to first, Barfield to second - G. Sizemore walked - C. Blake hit by pitch, J. Barfield to third, G. Sizemore to second - T. Hafner grounded into fielder's choice, J. Barfield scored, G. Sizemore to third, C. Blake out at second - V. Martinez singled to center, G. Sizemore scored, T. Hafner to third - F. Gutierrez flied to center I don't know if that changes the WPA value of that groundout or not, but it sure seems that it should, since it directly produced the game-winning run for his team. In a game reconstructed with a Martinez out following Hafner's groundout, the Indians still win, on Hafner's groundout. In a game reconstructed with a Hafner strikeout instead of the fielder's choice grounder, the Reds still lose if Martinez singles afterward, but there's no guarantee of that. To assume that Martinez would still have followed with an RBI single if Hafner had struck out assumes (smong other things) that the pitch selection to Martinez would have been the same after Hafner's K. I'm not sure that's valid to assume since: (a) Martinez would then have been batting with the bases loaded instead of first-and-third (i.e. a walk to Martinez would have forced in the go-ahead run for The Tribe) (b) The game would have still been tied; Instead of being mentally deflated by having allowed the go-ahead run to score, Santos is pumped because of having just punched out Hafner with the sacks drunk to get the second out of the inning. I realize that this last is a human factor that stats probably can't quantify, but it affects the outcome of the situation nevertheless. I also realize that the effect could go either way - perhaps after fanning Hafner, Santos would have gotten Martinez out...or perhaps striking out Hafner would have made Santos too big for his own britches and he'd have served up a three-run dinger to Martinez. At any rate, the ball was put into play, and the game-winning run crossed the plate on that play, which would not have happened on a strikeout (unless the third strike got away from Ross).

I find that hard to believe.

Seemingly, but those numbers count pitchers, both AL and NL. I don't consider that relevant and it's probably also putting him ahead of the pack on 3-2 counts. > Looks like the main thing missing for a clearer picture would be > opportunities in each situation.

I think it's pretty clear that he needs to make a 2-strike adjustment and I'm not sure what else there is to say. |
