"As we go into the second half, I'd hope that I would have at least [eighth-inning] and [ninth-inning] guys, and then you use your other guys to get there," Gibson said.
If he continues to improve, look for J.J. Putz to be the ninth-inning guy when the second half starts. Putz continues to look better as he builds arm strength again after being on the disabled list from May 8 until June 29.
"We'll just watch the way he throws when he throws, how well he bounces back," Gibson said of Putz. "We don't really want to continue go on and have one guy on one night and another guy on another night. I think in general when you have roles and everyone understands their roles that helps and lends to more consistency."
