PHOENIX, ARIZONA - MAY 20: Ketel Marte #4 of the Arizona Diamondbacks celebrates with third base coach JR House #71 after hitting a two run home run against the San Francisco Giants during the third inning at Chase Field on May 20, 2026 in Phoenix, Arizona.

He just had to go 3-for-3 with a walk and cross home plate as many times as the Giants’ entire team did in a 6-3 Arizona Diamondbacks win.
Tyler Mahle fell to 1-6 after giving up eight hits and six runs in five innings. At least he didn’t walk anyone! Merrill Kelly improved to 4-3 and won his ninth career game against the Giants, who went hitless in the final four innings of the game.
The team is 20-30, and they deserve to be. The Giants got on the board first when Casey Schmitt launched his ninth home run of the season in the first inning. Schmitt knocks his NINTH homer of the season 🥵️ pic.

In the third, he almost got a Desert Splash Hit by launching a two-run homer just to the left of Arizona’s outfield pool.
