San Diego Padres Fall 3-1 to Diamondbacks as Kelly Shuts Down Offense

San Diego Padres lost 3-1 to the Arizona Diamondbacks on July 10, 2026, as Merrill Kelly tossed seven solid innings, limiting San Diego to a single run and three hits. The defeat kept the Padres in 11th place in the National League with a 46-47 record, extending their losing streak to one game.

How did the game unfold?

Arizona struck first when a wild pitch by Griffin Canning allowed a run in the fourth inning. A two‑out RBI single by Geraldo Perdomo added another run in the fifth, giving the Diamondbacks a 2-0 lead. Nolan Arenado answered with a solo homer off Yuki Matsui in the sixth, his 11th of the season and 364th career blast, pushing the score to 3-0. The Padres answered back in the second inning when Manny Machado homered, his 19th of the year, but that would be their only run.

Why was Kelly’s performance pivotal for Arizona?

Kelly (7‑8) combined with two relievers for a three‑hit shutout, striking out six and walking three. He kept the Padres off the board after the early run, showing poise on the mound despite a leadoff homer by Machado. Kevin Ginkel closed the eighth inning perfectly, and Paul Sewald sealed the ninth for his 21st save, preserving the win.

What does this mean for the Padres’ season?

The loss drops San Diego further behind the NL West leaders, the Los Angeles Dodgers, who sit 14½ games ahead. The Padres remain stuck in the lower tier of the division, now 11th in the league. Their offense, which had erupted for ten runs in the previous game, struggled to generate more than a solo shot, highlighting ongoing consistency issues.

What’s next for both clubs?

Arizona’s left‑hander Eduardo Rodriguez (7‑3, 2.25 ERA) is slated to start against the Los Angeles Dodgers on Friday night. The Dodgers will counter with Shohei Ohtani (8‑2, 1.79 ERA). Meanwhile, San Diego will send JP Sears (2‑1, 4.70 ERA) to the mound against Toronto at home on Friday, hoping to bounce back after the narrow defeat.

Who stood out for San Diego?

Manny Machado’s second‑inning homer was the lone highlight for the Padres’ lineup. Despite a brief toe injury that kept him out the day before, he managed to find the fence, but the rest of the batting order could not capitalize on the early scoring opportunity. Pitcher Griffin Canning (1‑7) was charged with the loss after a wild pitch and limited run support.

How does this result fit into the broader picture?

The Padres’ 1‑3 loss to Arizona on July 10 marks their latest setback as they hover near .500. With the NL West dominated by the Dodgers, San Diego must find ways to string together wins against division rivals to climb out of the cellar. Their next series against Toronto offers a chance to reset and improve their standing.
