Wallach went 2-for-3 with a home run, two RBI, two runs scored and a walk Thursday against Houston.
Wallach drove in a run during the second inning on a single and went deep in the third. The 27-year-old backstop has gone 3-for-12 in spring games and could see substantial playing time at the beginning of the regular season depending on Jorge Alfaro's (knee) health.
