PHOENIX — It was, from every angle, an absolute disaster of a night.

Left-hander Robbie Ray, over 4 1/3 innings, surrendered two homers and allowed eight earned runs, the most he’s given up in a single game. Right fielder Jung Hoo Lee left the game early with back spasms. Shortstop Willy Adames homered but also left the game with an apparent injury. The defense committed three errors.

The result for the Giants was a 12-2 loss to the Arizona Diamondbacks on Monday at Chase Field. The 10-run defeat is tied for their largest margin of defeat this season.

Arizona’s offense set the tone for the night by absolutely ambushing Ray, needing just six pitches to plate four runs.

Ketel Marte singled on Ray’s second pitch of the night, and Corbin Carroll followed on with a single on Ray’s third. Ray’s fourth pitch induced a grounder off the bat of Geraldo Perdomo, but Matt Chapman committed an error as he couldn’t handle a tricky.

Finally, on Ray’s sixth pitch of the night, Nolan Arenado blasted his seventh career grand slam and his 35th career home run against San Francisco (20-28), the most he’s hit against any opponent.

Arizona had already established a commanding 7-2 lead going into the fourth inning, but the Diamondbacks blew the doors open by putting up a five-spot to take a 10-run lead. Ray exited the game after fielding a comebacker that deflected off his quad, but his night was likely done anyhow.

The blowout loss would’ve been enough agony, but there were injuries to match the insult.

First, there was Lee, who was lifted for Will Brennan after two at-bats due to back spasms. Then, Adames was pinch-hit for in the top of the sixth after he committed an error in the bottom of the fifth. Adames, who hit his fourth homer in the second, could be seen shaking his hand after the error, but the Giants have yet to announce why he left the game.

The oddest quirk of Ray’s outing was how he deviated from his usual pitch mix. Ray heavily relies on his four-seam fastball, throwing the pitch nearly half of the time (47.5%). On Monday, however, Ray’s heater accounted for 30 of his 84 total pitches, or 35.7%.
