Ryan Dempster has been the Cubs’ second best starting pitcher so far this season. After years of relieving, Dempster has really excelled this season in the rotation. Dempster has started 6 games for the Cubs this season and he is 4-0 with a 3.16 ERA and a 1.11 WHIP. Dempster needs to sharpen his control as he has walked 19 batters in 37 innings this season and that needs to change if he is to remain effective. He has only allowed 22 hits in 37 innings this season and that is why the walks haven’t hurt him yet but his stuff isn’t good enough to keep missing bats like he is right now.
