SEATTLE (AP) -- After eight innings, Felix Hernandez said he was done. The Milwaukee Brewers certainly had seen enough, too.
Hernandez left after pitching four-hit ball, leading the Seattle Mariners over the Brewers 2-0 Sunday.
Hernandez (12-5) struck out nine and walked one in his first career appearance against Milwaukee. The 2010 AL Cy Young winner leads the league with a 2.28 ERA and is second with 178 strikeouts.
This was the eighth time this year that he pitched at least eight innings. He was on track for his possible 10th career shutout, but a 20-pitch eighth inning pushed his pitch count to 108.
Acting Mariners manager Robby Thompson visited with Hernandez between innings and determined "he was at the end of his rope."
Said Hernandez: "I'm just being honest. I don't want to go out there, tired and lose the game."
Hernandez improved to 16-7 with a 2.63 in 30 career interleague starts, including 3-0 with a 1.16 ERA in four starts this season.
Danny Farquhar worked the ninth for his fourth save.
Wily Peralta (8-12) pitched a complete game and allowed four hits. He walked none and struck out four.
Justin Smoak hit a solo home run in the fifth, his 13th.
Hernandez allowed just one hit over his first five innings, a second-inning double by Juan Francisco. He was left stranded at third.
The Brewers had two hits in the sixth but still sent only three batters to the plate.
Martin Maldonado opened with a bunt single but was eliminated on a double play. Jean Segura then singled to deep short, but 41-year-old catcher Henry Blanco threw him out at second on steal attempt.
"He still throws them out," Hernandez said. "Unbelievable."
The Mariners, who lost the first two games in the series, ended a 12-inning scoreless streak with a gift run in the third.
Dustin Ackley opened with a double to left and moved to third on Brendan Ryan's right-side groundout.
On a 1-0 pitch to Blanco, Peralta bounced a fastball in front of the plate. The wild pitch caromed off catcher Martin Maldonado's shoulder and rolled several feet away. Ackley sprinted home for a 1-0 score.
Brewers manager Ron Roenicke added that Hernandez "is one of the best pitchers in the game for the few years now."
"Wily was really good. Really should have given up one run," he said.
