Martinez (14-8) allowed four runs on eight hits, including two homers in a loss to the Cubs on Wednesday. He also struck out nine and walked none over six frames.
The right-hander was cruising along, but then production from unlikely sources -- a Jon Lester single in the third and a David Ross homer in the fifth -- put Chicago ahead. Martinez also allowed a homer to Anthony Rizzo in the sixth. The good news is Martinez found his strikeout groove again. He struck out just one batter in his previous outing. Martinez will make his next start Tuesday against the Rockies in Coors Field.
