Smith started at designated hitter and went 1-for-1 with an RBI in Saturday's 6-2 loss to Texas.
Smith had his contract was selected from Triple-A Reno on Saturday, and was immediately inserted back into the lineup. His third-inning single knocked in the Diamondbacks' first run and was his lone plate appearance, as Ildemaro Vargas pinch hit for him in the fifth inning against left-hander Robert Garcia. Smith could get regular turns as a DH against righties, against whom Arizona ranks next-to-last in the league with a .684 OPS.
