Orioles 3, Yankees 2: Kelly Johnson delivered a walk-off RBI double in the bottom of the ninth inning as Baltimore stunned New York, which took a 2-1 lead on Brian McCann's homer in the top of the frame.

Nelson Cruz and Steve Pearce delivered back-to-back doubles to begin the ninth against closer David Robinson (2-5) and after J.J. Hardy flew out, Johnson ripped the first pitch he saw into the right-center gap. Chris Tillman allowed one run in 6 2/3 frames and hasn't lost in 12 starts since the All-Star break while going 5-0 with a 2.01 ERA during that span for the Orioles, who reduced the magic number to win their first American League East title since 1997 to three.

Martin Prado also homered while Hiroki Kuroda yielded one run in seven innings for the Yankees, who fell five games behind Kansas City for the final AL wild card spot with 14 to play. Darren O'Day (5-1) was credited with the victory despite yielding McCann's 20th home run of the season with one out in the ninth.

Prado drove a 1-2 offering out to left - just over the glove of Alejandro De Aza - leading off the second for his 12th homer of the season and seventh since joining New York on Aug. 1. Baltimore tied it in the sixth when De Aza singled with one out and scored as Adam Jones' double that glanced off the glove of Prado at third.

Yankees captain Derek Jeter, who is retiring after the season, went 0-for-4 and is hitless in his last six games and 24 at-bats - the second-longest streak of his career. Jeter, who received a bushel of crabs among his gifts during a pregame ceremony, finished with a .309 batting average in 140 games at Camden Yards, and his 184 hits are the most by an opposing player there.

GAME NOTEBOOK: Jeter's longest drought was an 0-for-32 spell in 2004. ... New York RHP Dellin Betances struck out two in a perfect eighth inning and has 130 this season, tying the franchise record for a reliever set by Mariano Rivera in 1996. ...
