OAKLAND -- The ball isn't supposed to fly on cool nights in the Coliseum, but you wouldn't know that from Monday's 14-8 Texas Rangers win over the A's in the first of a three-game series.

The temperature was 57 degrees at first pitch and fell from there, but that didn't slow the offense any. Texas hit four of the six homers that left the Coliseum en route to getting back to .500 at 35-35.

The American League West-leading A's (42-28) tried hard to rally after falling into a 10-2 hole, but the closest they got was 11-8 before back-to-back homers by Donnie Murphy (his second of the night) and Robinson Chirinos in the ninth put it away for Texas.

The A's scored two in the first, then had the bases loaded in the second in a 2-2 game and had a chance to put the hurt on the Rangers.

"We had some opportunities there in the second," manager Bob Melvin said. "After that, we didn't play very good baseball."

Not only did the pitchers, starting with Drew Pomeranz and ending with Fernando Abad, allow a dozen runs from the fourth through ninth innings, but the defense did more than its share of damage with three errors. Oakland now has 52 errors, the third-worst total in the American League.

Pomeranz gave up eight runs in just 32/3 innings after having allowed more than two runs in a start just once. His 1.90 ERA jumped to 2.91.

"He wasn't as sharp as we've seen him," Melvin said.

Few of the A's were, although new father Alberto Callaspo had a four-hit night and Yoenis Cespedes drove in four runs with a sacrifice fly and a three-run homer.

Two of the A's three biggest losses of the season in terms of run differential have come in the last four days, a 7-0 loss Friday to the Yankees and the six-run loss Monday. The A's also had a 7-1 loss to the Red Sox on May 2.

The A's got out of the gate quickly against Colby Lewis, with Coco Crisp's double and John Jaso's single producing a run before Lewis had recorded an out. Later in the first inning, a wild pitch got Jaso to third base, and from there he scored on Cespedes' sacrifice fly.

For the next four innings, however, the game completely belonged to the Rangers.

The real damage came in the fourth, starting when Murphy cracked a two-run homer. One out later, Daniel Robertson singled home a run, Elvis Andrus got another in with a grounder, and Shin-Soo Choo finished Pomeranz off by walking.

Reliever Ryan Cook, himself struggling this month, saw Adrian Beltre line a shot to right that Stephen Vogt simply couldn't handle. That double chased both of Pomeranz's runners home, making the Rangers' lead 8-2.

An inning later former A's outfielder Michael Choice, traded this winter for Craig Gentry, ended an 0-for-16 skid with a two-run homer for 10-2.

Oakland finally countered when Brandon Moss hit his 17th homer, a solo shot, in the fifth, but Texas got that run back on a sacrifice fly by Beltre.

  • Matt Chapman, the third baseman from Cal State Fullerton taken as their first pick in the draft two weeks ago, finally signed his contract Monday and took batting practice with the team. "It's awesome to be here and meet these guys," Chapman said. He will go to the A's facility in Phoenix for a few days to get acclimated, then will make the jump to Oakland's Class-A team in Beloit, Wisconsin. "It still doesn't seem real. My dream has always been to play professional baseball." He's getting a $1.75 million signing bonus.

  • Josh Reddick could be back in the A's starting lineup a week from Tuesday when the A's open a two-game series in New York against the Mets. Reddick, who did a full set of running drills Monday to test his hyperextended right knee, came through with the knee holding together. He will join the A's Triple-A Sacramento team in Round Rock, Texas, on Tuesday.
