Jason Castro not in the Astros' lineup for matchup with Arizona

Houston Astros catcher Jason Castro is out of the starting lineup on Thursday with flu-like symptoms.

What It Means:

Evan Gattis will start at catcher and bat fifth versus Arizona Diamondbacks' right-hander Zack Greinke. Castro came down the flu on Wednesday and could also sit Friday.

The 28-year-old is hitting .215/.349/.397 with four home runs and 14 RBI's in 146 plate appearances this season.
