Jackson’s strikeout rate perked up—8.7 SO/9—after moving to the bullpen last season, so the second act of his career may include waiting by the bullpen phone. Poor health sabotaged Hayden Simpson’s career. The 16th pick in the ’10 draft suffered from mononucleosis and an elbow tear before he even got going, but Cubs correspondent Phil Rogers lays the blame for Simpson’s failure at the feet of a previous front-office regime that didn’t want to spend in the draft. Nonetheless, Simpson (6.42 ERA in 161 innings) joins an ignominious list of pitchers selected by Chicago with its top pick: ’02 first-rounder Bobby Brownlie, ’04 second-rounder Grant Johnson and ’05 first-rounder Mark Pawelek. Cubs No. 2 prospect and the sixth pick in last year’s draft Albert Almora begins on the disabled list after breaking the hamate bone in his left hand.
