NEW YORK -- New York Mets left-hander Steven Matz has righted his ship since a disastrous season debut in which he allowed seven runs and recorded only five outs against the Miami Marlins.

Staked to a huge lead thanks to a record-setting third inning, Matz tossed six scoreless innings in an eventual 13-1 victory against the San Francisco Giants on Friday at Citi Field.

Matz (3-1) earned his third straight win. He has a 0.93 ERA in his past three starts.

Matz allowed seven hits and three walks and struck out four in six innings on Friday. He tossed 110 pitches, matching the career high set last year in his major league debut.

Before the Mets exploded for a dozen runs in the third inning, Matz had to wriggle free of multiple jams in a scoreless game as his pitch count rapidly climbed. He stranded two runners in a 24-pitch first inning by coaxing a hard-hit groundout from Hunter Pence. Matz then stranded runners on the corners in the third by retiring Buster Posey on a flyout.

Matz's performance after being staked to a 12-0 lead also impressed manager Terry Collins.

“You see a lot of young guys that go out there with that big lead and say, ‘I’m just going to throw my fastball,’” Collins said. “He didn’t do that. He tried to work both sides of the plate and he tried to pitch. That’s what impressed me about him.”

Matz was largely unaffected by the Mets’ 40-minute half-inning during which they scored the dozen runs. He threw some baseballs in the cage up the tunnel from the dugout during the 12-run explosion. He also loosened his arm using a massage machine.

“I felt really good coming back out,” Matz said. “I made a couple of stupid walks there, but I felt ready and felt like I was able to keep my rhythm.”

Said Collins: “It was a tough night to pitch. But our starting pitching is starting to get on a roll. We can ride that starting pitching a long time. And even if you fall into those situations where you’re not scoring, they’re tough to score off of.”
