Sean Sullivan pitched three scoreless innings with four strikeouts in his Arizona Fall League start Wednesday.

One of a handful of AFL players with major league experience, Sullivan went 0-3 with an 8.87 ERA in five starts for the Rockies last season. He’s getting some extra work in now after missing much of the second half with a shoulder impingement, and he’s been one of the league’s best pitchers with a 3.07 ERA and a very impressive 20/1 K/BB in 14 2/3 innings. The Rockies will surely add some pitching this winter, but if they leave an opening or two in their rotation, Sullivan will be in the mix next spring.
