One pitcher to watch this spring in Detroit's camp is lefty Kyle Bloom. The Tigs picked him up in the Rule 5 draft. He played in the Pirates' farm system previously.
From what I've read, Bloom has got a fastball that hit the upper 90s and a curveball that's already impressed Jim Leyland. Control issues have plagued him in the minors, but supposedly he made some adjustments late last season and finished strong. On the down side, he just turned 26 and has never pitched above Double-A.
He's tossed an inning this spring, striking out 2 and getting a save. He started 111 of 117 games in the minors, but his only hope with Detroit is in the pen. Bobby Seay is the only lefty reliever who figures to be a lock on the roster.
