Rockies set rotation for 2nd half of season

Rockies manager Jim Tracy says right-hander Aaron Cook

”realizes the fact that he has to pitch better.”

Cook is 0-4 with a 5.82 ERA in six appearances. He broke a

finger in spring training and missed the season’s first two


Tracy says Sunday that Cook will start Colorado’s fourth game

after the All-Star break. The second-half rotation will begin with

Ubaldo Jimenez on Thursday, followed by Juan Nicasio, Jhoulys

Chacin, Cook and Jason Hammel.

Tracy wants to split up the rookie Nicasio and the struggling

Cook, so the bullpen won’t get heavy workloads in consecutive


Tracy says Cook ”needs to get the ball down” and his ”sinker

can’t go side-to-side across the plate, it has to go down toward

the plate.”
