"I definitely think it has been a gradual return in performance as far as me feeling comfortable in locating the fastball and mixing in pitches," Cobb said on Friday. "That got a lot better this past week. My change is not as sharp, but I hope to get that down by tomorrow."
Cobb (8-2, 2.87 ERA), who missed 50 games with a concussion, said he's just dealing with the everyday issues that occur over the season.
"You're always battling issues throughout the season," Cobb said. "I had an endurance problem when I first came back. I'm beyond that now."
