PHOENIX — Landen Roupp almost received a gift. Almost.

The Arizona Diamondbacks, already leading by three in the third thanks to Lourdes Gurriel Jr.’s three-run homer, loaded the bases with two outs. Despite the threat, Roupp was one strike away from escaping. His 3-2 cutter to Jorge Barrosa, the No. 9 hitter, was supposed to be high and inside. It sailed into the opposite batter’s box, but there, for a split second, was the gift: Barrosa started to go around.

If Barrosa failed to hold up, Roupp would’ve, at the minimum, gotten through three innings. Maybe he could’ve even gotten through a fourth. But Barrosa held his swing and drew a bases-loaded walk. Ketel Marte followed Barrosa by driving in two on a bloop single, and Roupp’s shortest start of the season was over.

The Giants’ 8-2 loss at Chase Field on Tuesday night wasn’t just their eighth straight loss to the Diamondbacks to start the season, a night where third baseman Matt Chapman exited early with an abdominal strain. The defeat also marked the 11th straight game that San Francisco has lost when Roupp has started, the longest such streak since Pat Misch in 2007-2008.

As has often been the case, this team continues to make the wrong type of history.

“I’ve been pretty pathetic for the past two months,” said Roupp, who allowed six runs over 2 2/3 innings with six walks. “We’ve got to figure it out and get back to where I was at the beginning of the season because I’m not even giving the team, really, a chance to win right now.”

“You can’t go back in time and say everything would have went exactly how the rest of the game went if we get that guy out,” said manager Tony Vitello. “The way those first three innings went down … it kind of sets a tone. You’ve got guys trying, but nothing was good enough tonight.”

More pressing than the result of the game for the Giants, who match their season-low of 15 games under .500, is the status of Chapman, who aggravated his abdominal while fielding a grounder.

With two outs in the sixth, Chapman charged the grounder hard, barehanded the ball and fired across the diamond to end the inning, grimacing in pain as he hobbled off the field. He stayed in the game and hit for himself in the top of the seventh, but could barely jog down the first-base line when he hit an inning-ending pop out. Chapman was then removed from the game.

Chapman will undergo an MRI to assess the severity.

“For whatever reason, that was the first time that one specific play made me kind of like cringe and go down a little bit to where I was actually in a lot of pain,” Chapman said.

Chapman said his left hip flexor has been bothering him since April. By compensating for the left hip flexor, Chapman’s abdominal started to bother him, too. With shortstop Willy Adames dealing with a back ailment, Vitello said infielder Christian Koss will likely be added to the roster on Wednesday, the move yet to be determined.

Following Chapman’s departure, Luis Arraez moved from second base to third base. Rookie Jonah Cox, a primary outfielder, came off the bench to play second base and made a smooth diving stop in the bottom of the eighth to rob Marte of a hit.

“I kind of blacked out a little bit,” said Cox, who played four innings at second base in Single-A. “I think it’s one of those things where I’m happy it’s not the routine play because you don’t have as much time to think on that one.”

San Francisco’s only offense was solo homers by Arraez and Devers, their fourth and 15th homers of the season, respectively. Arraez finished a double shy of the cycle, logging a single and triple along with his home run.

“He was phenomenal,” Vitello said of Arraez. “Speaking of determination, he’s always got it. I don’t think there’s anybody out there that you could accuse of lack of overall focus or effort, but if we could match his energy and his determination as a group, we’d be in a pretty good spot.”

With Roupp failing to complete three innings, starter-turned-reliever Adrian Houser saved the Giants’ bullpen by tossing 5 1/3 frames of long relief, allowing just two runs in the process. In his first two relief appearances, Houser has allowed just two runs over 7 2/3 innings.

“He was outstanding,” Vitello said. “We’ve kind of put him a position that he’s not all too familiar with, not that comfortable. Definitely not his first choice. Given that he was on three days’ rest, tried to guard him a little bit. Pitch count wasn’t that high because he was so good, and he was determined as all hell to go out for that last inning. … It’s two times in a row he’s looked really good, and has been relentless in the strike zone.”

Up next

Trevor McDonald (2-6, 4.94 ERA) will take the mound as the Giants try to avoid being swept a third time by the Diamondbacks, who will start Zac Gallen (3-7, 6.15 ERA).
