Mack went 1-for-1 with a solo home run in Wednesday's 6-3 loss to the Rockies.
Mack has gone 12-for-40 (.300) with five home runs over his last 14 contests. The 23-year-old has seen fairly steady playing time at catcher since his first big-league promotion in early May. He's done well to earn the time, batting .256 with a .742 OPS, six homers, 22 RBI, 22 runs scored and five doubles over 146 plate appearances.
