"He's healthy this year," Yost said. "He never got 100 percent healthy last year. He had back issues, leg issues, shoulder issues. His body is alive right now. He's moving great, running great. He's mixing in big hits.
"You know you don't have to have nine guys hitting .300. You need the right combination to make it all work. Obviously it's working. We have the best record in the American League."
That doesn't mean Zobrist won't play some second base for Infante, who's hitting better lately, but still is at just .231.
"Is [Zobrist] going to fit in and play some second base?" Yost said. "Sure. He'll move around and he'll play everywhere. He's really good, so he's got to play. Gordy will need breaks when he comes back. We'll have breaks for Moose [Mike Moustakas], and Omar.
"But he's not going to second base strictly. Omar has been fine for me. He fits in the mix."
