ARLINGTON -- Khris Davis and Coco Crisp each belted two-run homers off Rangers reliever Matt Bush in the eighth inning to send the A's to a 6-4 win in the rubber match of a three-game set on Wednesday night at Globe Life Park.
The A's, who totaled three homers for the second straight night, have won all four of their series since the All-Star break, while the American League West-leading Rangers have won just one.
"Just a lot more confidence in our at-bats and as a team," A's manager Bob Melvin said. "Since we've come back for the second half, we really feel like we have a chance up and down the lineup until we're beat. It's been a good feeling."
The Rangers entered the eighth with a 3-2 lead, thanks to a two-run homer from Ian Desmond in the fifth. But with one out, Crisp lined a 99-mph fastball from Bush into the right-field seats to give the A's a 4-3 lead. Davis followed three batters later with his second homer of the night.
Davis' first home run was a solo shot in the first inning against Yu Darvish. The Rangers' starter gave up two runs in the first but allowed just two hits while striking out six for the rest of his six innings.
"It's tough. I felt like I let my team down today," Bush said. "Darvish had a great start. We were in great position to win a ballgame there and get us rolling."
A's starter Sean Manaea was on the hook for a loss after allowing the home run to Desmond in an otherwise solid performance. The rookie left-hander struck a career-high nine batters in 6 2/3 innings. He gave up a career-high 11 hits total, but an Adrian Beltre RBI single in the third was the only other blemish on his line.
"He gave up some hits, but he was like a boxer, he hung in there," Melvin said. "He got some big outs when he had to. He kept us in the game. Even though when he came out he was down, he pitched another really good game."
MOMENTS THAT MATTERED Davis getting it done: Davis has six homers and 14 RBIs in his last 18 games. He needs two more home runs to match the career high of 27 he set last season with the Brewers, and his 67 RBIs have already passed the 66 he posted last season. He had 69 RBIs the year before. Davis is clearly adjusting just fine to the AL, particularly the West. In nine games against the Rangers this season, he has seven home runs and 19 RBIs. More >
Desmond reaches 20 homers: Desmond's home run gave him his fourth 20-homer season in his eight-year career, and he is the first Rangers hitter to reach that mark this season. The outfielder had 19 home runs last season while playing shortstop for the Nationals. His career high for a season is 25, which he set in 2012.
Manaea limits the damage: Manaea came within one out of completing seven innings for the third time this month. The left-hander didn't issue a single walk, extending his streak to 27 innings without one, but he was bit by a handful of two-out hits, including Beltre's run-scoring single and Desmond's home run.
"It's been all about me refining my mechanics," Manaea said. "Early in the season, I thought I had a really good feeling, but there were still some timing issues. It's taken a couple months, but things are finally starting to pay off and everything is feeling really good."
Wrong place, wrong time for Rua: Trailing 2-0 with one out in the second, Ryan Rua got the Rangers' first hit of the game with a single to right field. They looked to have something going when Elvis Andrus hit a line drive that was headed for right field when it clipped Rua in the leg on his way to second base and the Rangers first baseman was ruled out. Nomar Mazara added a third consecutive single before Bobby Wilson struck out to end the inning.
"I've been on the opposite side, where I've hit it and someone else got hit a couple of times, but that was the first time that's happened to me," Rua said. "He inside-outed a pitch pretty hard the other way. You try to get out of the way, but there's nothing you can really do."
"It was one of those nights where everything goes the other team's way and they get to you. I don't want to look too deep into it, just keep my head up and be ready for tomorrow. " -- Bush, on giving up four runs in the eighth inning
