Though he'll hit the bench for the series finale, Vazquez may have temporarily pushed his way into a timeshare at catcher with the slumping Yainer Diaz. Since closing July with a pair of four-hit games, Diaz has produced a lowly .179/.233/.179 slash line through 12 contests in August. Vazquez drew starts over Diaz in each of the previous three games, going 2-for-6 with a solo home run, a walk and an additional run scored.

After serving as the Astros' primary option behind the plate for about six weeks, Vazquez has moved down to the No. 2 spot on the depth chart following Yainer Diaz's return from the injured list last Tuesday. In the Astros' ensuing six games, Diaz has made four starts to Vazquez's two.
