For the first time since April 3, the A's are under .500. And the defending AL West champions aren't pleased. "I just think we're playing bad in all areas of the game," third baseman Josh Donaldson said after Oakland's 6-3 loss to the Mariners. "We've got to get our fight back, our confidence." The A's have dropped five games in a row, a new season high, and they are five games behind first-place Texas, with Seattle just a half-game behind Oakland. The A's blazed out to an early division lead by winning 12 of the first 16 games, but have gone 6-15 since. Three outfielders (Coco Crisp, Josh Reddick and Chris Young) and No. 1 starter Brett Anderson are on the disabled list. "Offensively, we're not as good as we were early," A's manager Bob Melvin said. "We're getting behind early, putting the team in a hole. "Everybody has to pick everybody up and we're not doing that right now. We're struggling." Donaldson was involved in one of those early defensive plays, crossing in front of shortstop Jed Lowrie in the first inning on a big chopper by Kendrys Morales, what looked to be a potential inning-ending double-play ball. Donaldson stopped short when, he said, he saw Lowrie out of the corner of his eye. Lowrie, briefly blocked, said he lost sight of the ball for an instant. He couldn't react to the high hop and the ball got by him for a hit. "I'm not sure if it's a double-play ball, but it's definitely an out," Melvin said, adding of Donaldson, "If he goes to get it, he should. ... The last thing you want to do is block the shortstop out on the play." "I tried to stop and let him take over. That's definitely on me," Donaldson said. That put two men on for Michael Morse, and he singled up the middle to send in one run, and Justin Smoak doubled in the other. "It doesn't matter what happens behind me, it's my job to make pitches," starter Dan Straily said of the botched double-play ball.
