SAN FRANCISCO — Having won the night before, the Diamondbacks did on Tuesday night, May 13, what they have done for more than a week now. They followed a victory with a defeat.

But not only was their 10-6 loss to the San Francisco Giants their 10th consecutive day alternating between a win and a loss, it felt like another instance in which the Diamondbacks followed up a crisp, well-played game with one that manager Torey Lovullo would like to wad up and toss in the waste basket in the visiting manager’s office at Oracle Park.

His pitching staff issued six walks, four of which led to runs. His defense did not make all the plays. There was a wild pitch that brought home a run. And his offense couldn’t keep pace with that of the Giants, especially once the Diamondbacks’ bullpen entered the equation.

Before a reporter could even finish asking a question about the Diamondbacks’ inability to get into a rhythm from night to night, Lovullo was nodding along and ready to comment.

“I agree with that,” Lovullo said. “That’s very disappointing to me. We need to start playing really consistent, night after night. I know that we’re capable of doing it — I’ve seen us do it. It’s our standard here. But we’ve got to find a way to make it all sync up the way we normally do.

“When we do, we’re going to start to win a lot of baseball games.”

Diamondbacks right-hander Brandon Pfaadt struggled for the second time in his past three starts, giving up four runs and lasting just four innings. All the damage came in the form of a second-inning grand slam off the bat of Christian Koss, the first home run of the rookie infielder’s career, and Pfaadt labored through his other three innings.

The Koss slam erased what was a 3-0 lead that the Diamondbacks built in the first inning against Giants lefty Robbie Ray.

Pfaadt’s troubles in the second inning began with an infield single off the bat of Wilmer Flores, a ball to shortstop Jordan Lawlar’s left that he was unable to field cleanly.

Pfaadt then issued walks to Willy Adames and Patrick Bailey before Koss hit a down-and-in sinker that Pfaadt called “one of the few executed pitches we had today.”

He added: “That’s where we were trying to go with it.”

It was notable because most everything else Pfaadt threw did not go where he wanted.

“It felt like we were in three-ball counts pretty much all day,” Pfaadt said. “With the offense coming out in the first like that, it’s go time to get ahead and put guys away. We didn’t do that.”

Ray, who was making his first career start against his former team, gave up five hits in the first, including a run-scoring double by Eugenio Suarez and a two-run single from Josh Naylor. But the Diamondbacks were shut down over Ray’s next five innings.

The Giants improved to 9-0 in Ray’s starts this season.

The Giants added to their lead with three spots in the fifth and eighth innings. In the fifth, Willy Adames connected for a two-run shot off reliever Juan Morillo. In the eighth, it was Jung Hoo Lee who hit a line-drive homer off lefty Joe Mantiply that just cleared the high fence in right for a three-run shot.

Mantiply has given up four runs in 2 1/3 innings since returning from Triple-A Reno last week.

“It seems like every time he makes a mistake,” Lovullo said, “he pays for it.”

The Diamondbacks will complete a stretch of 16 games in 16 days on Wednesday afternoon, May 14. They are 7-8 through the first 15. Overall, they are 22-21 this season.

Perdomo welcomes Lawlar’s 1st start

With Jordan Lawlar’s first start of the season coming at shortstop, Geraldo Perdomo headed to the bench.

And Perdomo sounds completely on board with it.

“It’s OK,” Perdomo said. “I do want to mention something to everyone here in the clubhouse: The owner, the president, the GM, they invested a lot of money in this team and all these players, but at the end of the day whatever is the best decision for the manager and the GM, to put the best lineup to win, everybody has to be on board with that decision.”

Manager Torey Lovullo said he spoke on May 12 with Perdomo and second baseman Ketel Marte about the possibility of Lawlar getting starts at their positions in the coming weeks. He said he had yet to find time to chat with third baseman Eugenio Suarez but plans to do so.

“Everybody’s receptive to it,” Lovullo said. “I think they all know they can’t play every day. And eventually they will. I’m not saying this is something that’s going to go all the way through August and September because things change. I want guys to be as fresh as possible at the most meaningful time of the year.”

Lawlar is hitting eighth against the Giants, one day after getting recalled following a scorching hot start at Triple-A Reno.

Both Lovullo and general manager Mike Hazen have said Perdomo, Marte and Suarez remain the club’s everyday players, adding that they expect Lawlar to get “three or four” starts a week bouncing around the infield.

Perdomo said the Diamondbacks “don’t have any egos in here,” adding that he was glad to see Lawlar back with the team.

“He deserves to play,” Perdomo said. “He’s a great player. I don’t care if he plays shortstop, second, center field — if he is in the lineup and he’s going to help us to win, then it’s the best decision and I’m going to agree with that. I don’t care if I’m hitting good or bad, there’s no ego. He’s my brother and I’m going to support whatever decision they make for the team.”

Perdomo said the uncertainty about Lawlar’s long-term position doesn’t change how he views him going forward.

“I feel like he’s going to be a big part of this thing,” Perdomo said. “Unfortunately, he got hurt last year, but he’s been here since 2023. He deserves to play. He’s a good player. There was a reason he was the sixth overall pick (in 2021). He deserves to play.

“If the manager feels like he needs to play, no one can be mad. I don’t care if it’s me, I don’t care if it’s Suarez, I don’t care if it’s Marte — no one can be mad. If he’s going to help this team to win, then it’s a good decision.”

Banister back with team after health scare

Bench coach Jeff Banister was back with the Diamondbacks on May 13 and feeling good after missing the previous night’s game due to a health scare.

Banister, 61, said he experienced an episode of what doctors determined was transient global amnesia, a condition in which a person is unable to form new memories for a period of time.

“When I woke up yesterday morning, I obviously felt worn out,” Banister said. “I talked to Karen (his wife) on the phone. I told her I was going to go lay back down and take a nap. Next thing I knew I found myself here at the clubhouse and didn’t know how I got here.”

He said he went through a battery of tests that determined he did not have a stroke or any heart issues, adding that his “body is good, mind is still good.”

Banister believes he hasn’t been taking good enough care of his body in the sense of eating right, drinking enough water and getting enough sleep.

“I’ve been a guy that pushes hard for the last 40 years,” he said. “I’ll still be that guy, but paying attention to making sure we take care of ourselves is paramount.”

Banister said he was thankful to be surrounded by good people with the club who pushed him to get checked out “when I probably didn’t want to.”

“I feel great today,” he said. “I woke up this morning a clear head, clear eyes. Body feels good. It’s nice to have great people around you to take care of you. I feel tremendous today.”
