Diaz went 1-for-3 with a home run and two RBI in Saturday's 5-4 loss to the Astros.
Diaz drove in a game-tying run in the fourth inning on a sacrifice bunt and then homered in the sixth to bring Texas within one run. The RBI were his first in 18 contests. He's getting most of the starts at catcher with Kyle Higashioka (forearm) on the injured list.
