"It's a tough situation sometimes with the lineup out there that you feel good about winning games, certainly depending on matchups and all the information that we got," Williams said. "We try to balance it. It's not easy."
It wouldn't come as a surprise if Espinosa started in Saturday's game with right-hander Doug Fister on the mound. Fister is a groundball pitcher and Williams has started Espinosa a few games last year when Fister took the ball.
"We want to get [Espinosa] in there more than once a week. That's for sure," Williams said. "It depends on where we are at, what's going on -- health, nix and dings and things of that nature. That's an everyday dilemma, an everyday question. We'll try to do it accordingly," Williams said.
