On Monday against Peoria, Baker served up hits to the first three batters he faced, including a two-run homer to Nick Martini. The right-hander was pulled after giving up two runs on six hits over 5 2/3 innings, striking out four. He did not walk any of the 23 batters faced.
Although Baker has been a starter, Cubs manager Dale Sveum said Monday that if the right-hander were added, he'd pitch out of the bullpen.
"If anything right now, if we do activate him here, he'd just be a long guy," Sveum said. "There's no plans to have him start or anything, unless there comes a point where we feel somebody needs a five-day break instead of four days. Right now, that's all wait and see."
Baker went five innings in his previous outing for Kane County, giving up one hit. He retired 13 of the first 14 batters he faced.
