The 24 year-old showed a negative trait, however: walks. Fish walked 18 hitters in those 30 1/3 innings, but with all due respect, seven of those came in one disastrous appearance in September. Take that outing out, and Fish struck out 41 and walked 11 in 28 2/3 innings. Combine that with the 19 hits he allowed (again, excluding that seven walk appearance in September, where he also allowed two hits), and Fish had a fantastic 1.367 DOM on the season. That is a fantastic number.
In AA last year, Fish did show some platoon splits against lefties and righties. Against lefties, he walked four and struck out 17 in 11 innings (1.133 DOM). Against righties, he struck out 24 and walked 14 in 19 1/3 innings (0.800 DOM). That's a definite split, and he could have a role on the team as a lefty specialist, much in the role that George Sherrill had last year (and was effective at, despite fans and their silly anti-Sherrill crusade).
Fish has thrown just 2/3 of an inning in AAA, and his lack of experience at the level could submarine his chances at making the major league roster. He's a nice guy to have in the organization, and I hope that even if he doesn't make the major league roster, the Braves are able to work something out with the Angels to keep him in the organization.
