Rapid Reaction: A's 5, Yankees 4

WHAT IT MEANS: The Yankees played one of their sloppiest games of the season and paid for it.

The team committed three errors -- one short of its season-high -- in a 5-4 loss to the A’s on Sunday afternoon at the Stadium.

The Yankees, who came in having won seven in a row, kept their one-game lead in the AL East, though, because the Orioles lost to the Red Sox, 2-1.

NUNEEEEEEEEE: Eduardo Nunez committed two errors: a throwing error in the fifth and a fielding error in the seventh. He now has nine miscues this season. Nunez also went 0-for-4 at the plate and struck out with the tying run aboard at second in the eighth.

NOT A HIRO TODAY: Hiroki Kuroda has been the most reliable starter in the Yankees’ rotation this season. He just wasn’t on Sunday. Kuroda labored through 5 2/3 innings, allowing five runs (four earned) on seven hits and throwing 102 pitches. Three of those runs came in the first two frames -- the lowlight being when Cliff Pennington got a hold of a hanging slider from the 37-year-old Japanese right-hander and parked it for a two-run home run to right in the second.

BIG DADDY KANE: Nick Swisher seemed to stand there and admire his two-run homer in the fourth -- No. 22 on the season -- a little longer than usual. Perhaps it had something to do with Eric Chavez’s critical comments Saturday?

K-ROD: Alex Rodriguez struck out three times, grounded to third and flied to deep right -- just shy of the wall -- in the ninth.

GOING STREAKING: Derek Jeter extended his hitting streak to 17 games with a third-inning single to right.

WIZARD WATCH: Ichiro, who came in 14 for his previous 20, singled in four at-bats and added a stolen base.

BAD CALL: Prior to Pennington’s homer, Josh Donaldson was called safe by first base umpire Larry Vanover on a leadoff infield hit to short, but replays showed that he was out.

SO COOL: Following up on his big day Saturday, Raul Ibanez had two hits on Sunday -- including an RBI double.

UP NEXT: Andy Pettitte (4-3, 2.97 ERA) makes his second start since coming off the disabled list on Monday night in Minnesota. Check out Andrew Marchand’s First Pitch blog on Pettitte in the morning.
