I'm not real fond of W-L, but Slegers did have himself a nice AAA. season. For a little closer look at the game-by-game results, Baseball-reference.com provides a version of Bill James's "Game Score" in their game log, where a score of 50 and above represents something fairly close to a quality start, and Aaron had 15 of those in his 24 starts at Rochester, 4 so-so games with scores 40-49, and 5 stinkers below 40. Perhaps more importantly, he got 4 of those 5 stinkers out of his system by early June, and compiled a nice streak of 11 games of 40+ scores, most of those being 50+. That's the kind of consistency I imagined the front office was looking for before they would call him up, and they did indeed add him to the 40-man for a spot start in August, and then invited him for September as well. Come to think of it, 15 good starts and 5 stinkers comes pretty close to that 15-4 W-L, with the fluctuations happening to basically cancel out, but I still trust game scores a little better. I don't hype him as a future ace, obviously, but I see his upside as rotation workhorse more than just fifth starter.
