He was lights out last year for the last two months of the regular season. August ERA: 2.57 September ERA: 2.37 He had a bad postseason (8.80 ERA in 15 IP). He was mediocre in two of his postseason starts: Oct 4, 2007: 3 runs in 5 IP, 4 hits, 6 BB, 5 K Oct 18, 2007: 4 runs in 6 IP, 10 hits, 2 BB, 6K And he was awful in one start: Oct 12, 2007: 8 runs in 4 IP, 7 hits, 5 BB, 3 K Overall, in the playoffs his walks were way up from career norms, and he gave up way more flyballs (51% groundballs) than during the regular season (57% groundballs) resulting in surrendering more home runs(1 every 5 IP) than typical for him (1 every 12IP). I guess there are a number of ways to read this data. 1. He was worn out. Lost command, couldn't locate, etc. 2. His three postseason starts were against the Yankees, @ Boston, and Boston. The 2007 Yankees led baseball in runs scored with 968 (the most by a Yankees team since 1937!). Boston was 4th in baseball with 867 runs scored. Good offenses=more runs scored than average 3. Some mumbo-jumbo about wilting under the intense spotlight of the playoffs. 4. Our good friend Small Sample Size. 5. Some combination of all/some of these factors. In summation, I guess I'd pull him if the game is in hand (or if he is hitting 120+ pitches), but I'd roll the dice that his postseason last year was simply an anomaly, and not indicative of the beggining of a trend or pattern.
