In the fifth inning, second baseman Adam Kennedy booted a potential inning-ending groundout off the bat of Rafael Furcal. The next batter, Orlando Hudson, singled to drive in the first run of the game for the Dodgers.
In the sixth, Casey Blake reached on a throwing error by Orlando Cabrera, and Blake later scored in the inning.
Then in the seventh inning, things got a little strange. After a leadoff walk, right fielder Jack Cust dropped an easy popup to put runners at first and second.
"That's the first one in a long time," manager Bob Geren said of Cust's miscue. "He just dropped the ball. I don't know what happened."
The next batter, James Loney, lifted an easy popup to short, but Cabrera dropped it, and suddenly, the A's looked more like the Bad News Bears than a Major League ballclub.
Fortunately for the A's, Cabrera's gaffe didn't matter. Loney was out via the infield fly rule. But Cust's seventh-inning error did lead to two runs. After Blake singled, Andre Ethier followed with a two-run hit.
In all, the A's committed three errors, not including Cabrera's drop.
"It was a poor defensive performance by us," Geren said. "We've been a real solid pitching and defense team. Our defense let us down today and fortunately we held on to win."
