Arizona Diamondbacks drop series opener to Padres 10-4, fall to 45-47

The Arizona Diamondbacks lost 10-4 to the San Diego Padres on Wednesday night, July 9, 2026, at Petco Park. The loss dropped Arizona to 45-47 on the season, 11th in the National League, and extended their losing streak to two games.

What happened in the game?

Luis Campusano homered and Miguel Andujar added a career-high three doubles for San Diego. The Padres jumped ahead early and never looked back, tying their season high in runs.

Michael King (6-7) pitched six strong innings for the Padres. He allowed just one run on four hits, struck out four, and walked two. It was enough to hand Arizona its second straight loss.

Diamondbacks manager Torey Lovullo was ejected in the fifth inning. Plate umpire Willie Traynor called a balk on reliever Jose Cabrera (0-2) that put runners on second and third with one out. Lovullo argued and got tossed — his 24th career ejection.

Xander Bogaerts followed with a single to left, scoring both runners for a 4-1 Padres lead. That broke the game open.

How did the Diamondbacks' pitching perform?

Cabrera started and took the loss. He went 4 1/3 innings, allowing four runs on four hits. The balk call hurt, but the Padres were already putting pressure on.

Taylor Clarke came on in relief and gave up Campusano's solo homer to left-center in the sixth. That was his fourth of the year. Then Sung-Mung Song, Fernando Tatis Jr., and Jackson Merrill all hit RBI singles in the same inning.

Andujar added RBI doubles in the fourth and seventh. He scored twice. The Padres piled on 10 runs total.

Tommy Troy hit a two-run homer off Ron Marinaccio in the seventh, his fourth. By then, the game was well out of reach.

Why this loss matters for Arizona

The Diamondbacks came into the night tied with the Padres, both 14 games behind the Los Angeles Dodgers in the NL West. Both teams were also five games out of the third wild-card spot, with three teams ahead of them.

Arizona needed this one. They didn't get it. Now they're 45-47, still in 11th place in the NL, and the losing streak is at two.

Every game counts when you're chasing a playoff spot. The Diamondbacks have to start stacking wins soon or the gap will only grow.

What comes next?

The series finale is Thursday night at Petco Park. Right-hander Merrill Kelly (6-8, 5.71 ERA) starts for Arizona against Padres righty Griffin Canning (1-6, 6.71).

Kelly needs to give the Diamondbacks length. The bullpen has been taxed, and the offense has to wake up. A series split would at least stop the bleeding.

First pitch is scheduled for 7:10 p.m. Phoenix time. Arizona will try to avoid a third straight loss and get back to .500.
