OAKLAND, Calif. -- On Throwback Thursday at O.co Coliseum, Yu Darvish had a flashback to his first inning as a major-league starting pitcher.
And that's not a good thing.
The right-hander struggled to throw strikes two months ago against Seattle, and when he did, the ball found its way into the outfield. Four runs later, he had recorded his first three big-league outs.
Darvish hadn't experienced another inning like that until the fourth inning Thursday. Unlike April, though, the Rangers' offense was in no position to bail him out.
Coco Crisp had a three-run triple in a four-run fourth against a wild Darvish, and Brandon McCarthy allowed one run in seven innings as Oakland cruised past the Rangers 7-1 for its third win in the four-game series.
Darvish established career-highs for runs allowed with six, surpassing the five-spot he allowed in his debut, and has lost three of his past four starts.
His ever-changing mechanics were the issue Thursday.
"Mechanically in that inning, it was very awful," Darvish said. "After the game I looked at the video and figured out what I was doing wrong. Even until the end, I couldn't really fix it today."
Crisp also homered in the third as the Rangers lost a half-game off their lead in the American League West. The margin over Anaheim is four games as the Rangers ahead across the bay for a three-game series at AT&T Park, where they are 0-11 all time.
Oakland scored once on three hits in the first and again as Crisp found the empty seats in right field. But the Rangers quickly countered with an RBI single from Adrian Beltre in the fourth, and the Rangers were down 2-1 when Darvish went back out.
He retired Seth Smith on the first pitch of the inning, but walked Brandon Inge and Brandon Moss. Darvish was ahead 1-2 on Kurt Suzuki before plunking him to load the bases.
"After the Brandon Inge at-bat, it went south," Darvish said.
Cliff Pennington lifted a sacrifice fly for the second out, but Darvish walked Jemile Weeks to extend the inning. After falling behind Crisp 2-0 in the count, the outfielder ripped a ball over Nelson Cruz's head in right field to clear the bases.
Crisp entered the game hitting .158 and with six RBIs.
"He looked like our Hamilton today," Darvish said.
With Scott Feldman and Alexi Ogando scheduled to start Saturday and Sunday, Darvish lingered into the sixth inning as manager Ron Washington tried to save the bullpen from a heavy weekend workload.
Darvish (7-4) threw 110 pitches but only 61 strikes as he matched his career-high with six walks. He now leads the majors in walks allowed, at 44.
"It was the walks that hurt him," Washington said. "You start putting that many guys on the bags, something bad will happen. And it did."
The offense, meanwhile, had no answer for McCarthy and was largely inept for this week at O.co Coliseum. They scored only eight runs in four games, and six of those came in Tuesday's victory.
McCarthy (5-3) retired the final 11 batters he faced after surrendering the Beltre single that scored Josh Hamilton, who had doubled.
"Over the last three years, this is out of the ordinary," Hamilton said. "What's made us so good is, when two or three guys are struggling, somebody else is getting it done. Right now, nobody is.
"It's not like this was never going to happen. We don't panic. We don't stress. We just go out and play."
