Smith went 1-for-1 with a pinch-hit three-run home run in Wednesday's win over the Giants.
Smith didn't enter the game until the bottom of the eighth when he was brought in to pinch hit for Randal Grichuk with two runners on. The outfielder then came through in a big way, launching a three-run home run off Spencer Bivens on the third pitch he saw to extend Arizona's lead to six runs. The long ball was Smith's ninth on the campaign and his sixth in the month of September, where he's batting .310 with 12 extra-base hits, 19 RBI and 13 runs scored.
