As the San Francisco Giants get ready for another meeting with the Houston Astros, there will be a bit of a shakeup behind the dish. Buster Posey will return to the squat on Wednesday, instead of Hector Sanchez, the man that usually catches Barry Zito.

Sanchez played hero Tuesday night with a pinch-hit RBI in the ninth inning to clinch victory for San Francisco, but skipper Bruce Bochy wanted Buster to catch the former Cy Young winner this evening. Zito has a 0-2 record with a 10.00 ERA in his last two starts against Houston, which may be playing a part in this move.

Your San Francisco Giants:

1. Angel Pagan CF
2. Marco Scutaro 2B
3. Pablo Sandoval 3B
4. Buster Posey C
5. Hunter Pence RF
6. Joaquin Arias SS
7. Brandon Belt 1B
