Manager’s Remarks

“That’s kind of when he’s at his best,” Giants manager Bob Melvin said of Webb. “It’s never really about strikeouts with him. It’s about early-count weak contact, and that’s what we saw basically the entire game. … I’m just glad I’m on his team.”

Added Webb: “It felt really good. I feel like me and (catcher Patrick Bailey) are getting really dialed in with the sequences and what we’re trying to do. It’s been fun working with him. And also, the defense played unbelievable.”

Mike Yastrzemski, Thairo Estrada, and Michael Conforto each had two hits for San Francisco. Yastrzemski had three RBIs, and Estrada and LaMonte Wade Jr. drove in the other runs.

Starling Marte had three hits for New York, which lost its third straight game after a six-game winning streak.

Game Highlights

Mets starter Luis Severino carried a perfect game into the fifth inning before Conforto led off with a bloop single to left field and Matt Chapman followed with a sharp single to right.

After a flyout by Bailey, Estrada drove in the game’s first run with a single to left. Chapman advanced to third and Estrada took second on Jeff McNeil’s throw home.

Yastrzemski’s single to center scored two runs and the Giants led 3-0.

Severino (2-2) allowed three runs and five hits in six innings, striking out five.

Estrada led off the seventh with a triple and scored on a single by Yastrzemski. Wade added an RBI double to make it 5-0.

New York tried to rally against Giants reliever Tyler Rogers in the ninth, scoring a run on DJ Stewart’s RBI fielder’s choice.

Camilo Doval came in with two runners on and recorded the final two outs for his fourth save.

“We’re playing better now,” Melvin said. “We’re getting some big hits when we need to, we’re playing solid defense, we’re getting better pitching across the board.”

San Francisco improved to 8-0 when scoring at least five runs.

Trainer’s Room

Mets catcher Francisco Alvarez underwent surgery on his sprained left thumb and is expected to miss approximately eight weeks. … Veteran slugger J.D. Martinez, who signed a $12 million, one-year contract late last month, reported to Triple-A Syracuse and went 1 for 4 with an RBI single.
