After San Francisco’s Mike Yastrzemski hit an RBI double with two outs in the second, Myers hit a solo homer with one out in the second, his 12th.

Tim Hill (3-0) pitched a perfect fifth for the win. Trevor Rosenthal pitched the seventh for his 10th save in as many chances.

Giants starter Logan Webb held the Padres to one run and four hits in four innings. San Diego’s Garrett Richards, coming off his best start of the season, allowed one run and two hits and left with two outs in the fourth and the score tied at one.

Clevinger said he didn’t have a good session warming up, but then he came out and struck out leadoff batter Yastrzemski on a 98 mph fastball.

“Surprisingly enough, that’s usually how it works when your bullpen’s not good,” he said. “I had a not-so-excellent bullpen before this day and the second I’m on the mound, I felt like everything was there.

“I felt like I got in a good rhythm,” said Clevinger, who was making his third start since coming over from Cleveland in a blockbuster trade on Aug. 31. “This was kind of the the first time I was on back-to-back five-day schedules in a while so it was good to feel that pattern. It’s easier to find my patterns and my delivery by staying on routine.”

Clevinger (3-2) struck out seven and walked one in seven innings for his second career complete game.
