Lester Oliveros

Oliveros was traded to Minnesota from Detroit for Delmon Young and will try to win a spot in the Minnesota bullpen this spring. He started last season strong with an 0.56 ERA and 27:4 K:BB ratio in 16 innings for Double-A Erie. He struggled after he was promoted to Triple-A with a 6.10 ERA and 30:17 K:BB ratio in 31 innings. Despite his Triple-A struggles, he was called up to Minnesota in September and had mixed results. He's had outstanding strikeout rates in the minors (and even struck out nine batters in 13.1 major league innings with the Twins), but has struggled with his control. He has a mid-90s fastball, so it's possible the Twins could refine his skills into a productive setup man. Until then, he'll likely spend much of the season at Triple-A.
