Blanton simply outpitched and overshadowed the 19-year-old right-hander.
Blanton threw eight sharp innings of two-hit ball, leading the Oakland Athletics to a 5-0 win Friday night that snapped the Mariners’ three-game winning streak.
While Hernandez pitched like an inconsistent teenager making his 13th major league start, Blanton (1-0) was outstanding. He allowed only a groundball single by Jeremy Reed in the third and an infield hit by Raul Ibanez in the fourth. The right-hander struck out six, walked one and did not allow a runner to reach second.
“It’s one of those where the other pitcher is getting a lot of attention, but I’m not facing him. I’m pitching against their lineup,” Blanton said. “He doesn’t have anything to do with the way I approach the game.”
Blanton retired 10 straight batters during one stretch, but wasn’t allowed to go for the complete game despite throwing only 98 pitches. Justin Duchscherer struck out two in a hitless ninth to finish the shutout.
“That’s about as good a stuff as he’s had, the total package,” Oakland manager Ken Macha said. “The curveball was excellent, the slider had good depth on it, the changeup was excellent. He threw a lot of strikes.”
Meanwhile, Hernandez (0-1) struggled for stretches on the eve of his 20th birthday, and yet was barely hittable. He allowed one run and two hits in five innings, but walked four and threw 100 pitches.
“I didn’t have control of any of my pitches,” he said through a translator. “I was trying to gain control and when I finally did I was able to do a little better, but not much.”
Oakland managed just five hits but took advantage of 11 walks, six by Mateo. The A’s didn’t need much offense thanks to Blanton’s performance.
“We were fortunate to get the two hits we got,” Seattle manager Mike Hargrove said.
The A’s were extremely patient at the plate against Hernandez, and his pitch count grew quickly. He threw 25 pitches in the first inning and was at 50 after three. Nick Swisher was the only batter to swing at the first pitch in both plate appearances against Hernandez.
“Obviously, we know he’s got electric stuff. We wanted to work him and get his pitch count up, and we were successful at that,” Kotsay said.
The right-hander was pitching in a game for the first time since March 23, skipping his last spring training start to rest some shin splints. At times, he flashed the talent that has many proclaiming him as the best young arm in baseball, but the layoff was noticeable to Hernandez and his manager.
“I think we saw the result of not pitching in a game,” Hargrove said. “Even at that, they only got two hits off him. But he was behind a lot of hitters and threw a lot of pitches.”
Hernandez again showed resolve in the fifth as his pitch count inched toward the century mark. After Kotsay’s double, he hit Mark Ellis with a 1-2 fastball, but rebounded to strike out Chavez looking on three pitches, the last his 100th of the game.
Hernandez threw 56 strikes and reached 96 mph on the stadium’s radar gun. He gave up one run and two hits in five innings, striking out four and walking four.
“I did everything I could,” he said. “It was a battle.”
Mateo replaced Hernandez in the sixth and walked the bases loaded with two outs. Swisher then lined a shot off the wall in center. Thomas scored, but Bradley stopped and went back to third, appearing to have missed the base.
Reed quickly relayed the ball from center to Willie Bloomquist, who threw home. Catcher Kenji Johjima threw to Adrian Beltre at third, who tagged Bradley halfway between third and home to end the inning.
Seattle got a scare in the eighth when Beltre was hit on the right wrist sliding into second as Scutaro attempted to turn a double play. X-rays on Beltre’s wrist were negative.
Macha plans to play SS Bobby Crosby on Saturday. Crosby hasn’t played since opening day after injuring the index finger on his left hand. … Hernandez was the only teenager to make an opening day roster. … Beltre was 0-for-2 with a walk on his 27th birthday.
