"Hopefully, it won't be too long that Anthony may have to play second base," Williams said. "That would mean that Harp's back."
Williams said Zimmerman is still an option at third base, but it's important to be mindful of his recently healed thumb and throwing shoulder.
"If he came back into third base, he's been doing it a long time, it's not like it's going to be foreign," Williams said. "At some point, he's going to be back in there."
