"I like the way he looks," manager Joe Maddon said. "He's around the plate, throwing strikes. The biggest two things I watch for when a guy comes off an injury would be command -- and part of that is, 'Is he guarding at all?' I don't see him guarding in his finish. I think he's on a good track."
While Maddon likes what he's seeing, he conceded that Balfour isn't quite back to the lofty plateau he had reached before getting injured.
"He was going pretty good [when he got injured]," Maddon said. "His velocity was way up there. His arm strength was built up. You could use him two or three days in a row. We've got to get back to that point. I'm saying he's going to get back there relatively soon."
