The Houston Astros got some tough injury news on Tuesday night.

Zack Greinke is dealing with "some soreness in his arm," according to Dusty Baker. Jose Urquidy will take the ball in Game 3 opposite the Oakland Athletics' Jesus Luzardo.

Greinke 36, hasn't completed six innings since Sept. 8 and has a 5.79 ERA over his past four starts.

"Greinke's ailing some," Baker said. "He didn't say much about it, but it was pretty evident the last three or four starts that he wasn't himself."
