Alonso went 1-for-4 with a solo home run in Thursday's win over the Diamondbacks.
The 29-year-old slugger took Ryne Nelson deep in the second inning to get the Mets on the board. Alonso has picked up the pace in August, slashing .253/.345/.505 with seven homers and 17 RBI in 26 games, and he sits one long ball short of his fourth straight 30-homer campaign and the fifth of his career.
