NEW YORK (AP) - The Boston Red Sox lost yet again, with A.J. Burnett making his most impressive start in nearly three months and Jorge Posada hitting a two-run homer that led the New York Yankees to a 6-2 victory in the opener of Sunday's day-night doubleheader.
Boston's AL wild-card lead was cut to a half-game over Tampa Bay. What was a runaway nine-game advantage heading into play on Sept 4 would be completely gone by the end of the night if the Yankees swept.
The Red Sox have lost four straight and at 5-18 (.217) are on track for their worst September since going 4-18 (.182) in 1926, according to STATS LLC. Tim Wakefield (7-8) dropped to 1-5 in his last 10 starts.
Derek Jeter had three hits to lift his average to .300 at the end of the game for the first time since April 2. Burnett (11-11) allowed two runs and five hits in 7 2-3 innings.
Rays 5, Blue Jays 2
ST. PETERSBURG, Fla. (AP) _ B.J. Upton and Ben Zobrist homered in the first inning to back Wade Davis, (11-10).
Evan Longoria and Kelly Shoppach also homered for the Rays, who have closed the gap with Boston despite going 14-10 in September. Joel Peralta finished for his sixth save in eight chances.
Tampa Bay closes at home against the Yankees, while the Red Sox play at Baltimore.
Athletics 6, Angels 5
ANAHEIM, Calif. (AP) _ Rookie closer Jordan Walden (5-3) wasted a 5-2 lead in the ninth inning, throwing away a potential game-ending grounder. The defeat left the Angels 2 1-2 games behind Boston and two games back of Tampa Bay.
But Josh Willingham homered leading off the ninth and, after a pair of singles, Walden threw Adam Rosales' comebacker past shortstop Erick Aybar and into center. Kurt Suzuki followed with a tying double, and Coco Crisp's second sacrifice fly put the A's ahead.
Fautino De Los Santos (3-2) allowed Peter Bourjos' two-run single in the eighth, and Andrew Bailey pitched a hitless ninth for his 23rd save.
Rangers 12, Mariners 5
ARLINGTON, Texas (AP) _ Yorvit Torrealba homered in consecutive innings, including a grand slam, after Derek Holland (16-5) pitched his scheduled five innings in a postseason tuneup.
Adrian Beltre and Ian Kinsler also homered for the Rangers, who matched a franchise record with their 52nd win at home.
Texas stayed a game ahead of Detroit for the second-best record in the AL and homefield advantage in the first round. Charlie Furbush (4-10) was the loser.
Tigers 10, Orioles 6
DETROIT (AP) _ Miguel Cabrera homered and singled to raise his average to .341 in his push for the AL batting title, then left because of lightheadedness.
Brad Penny (11-11) allowed three runs and five hits in 5 1-3 innings for the win.
Brian Matusz (1-9) gave up six runs and seven hits in five innings. Assuming he doesn't pitch again this year, Matusz will finish with a 10.69 ERA, a record high for a pitcher with at least 40 innings in a season, according to STATS.
Twins 6, Indians 4
CLEVELAND (AP) _ Rene Tosoni led off the 10th inning with a home run off Tony Sipp (6-3) to give Kyle Waldrop (1-0) his first career win. Chris Parmelee added an RBI single later in the inning.
Cleveland had a four-game winning streak snapped. The crowd got a surprise in the ninth when 41-year-old Jim Thome made what could be his last appearance at Progressive Field _ as a third baseman, a position he had not played since 1996.
Royals 2, White Sox 1
CHICAGO (AP) _ Luis Mendoza (2-0) allowed one run and five hits in 7 2-3 innings, Jarrod Dyson hit a two-run double and Kansas City sent Chicago to its 11th loss in 15 games, ensuring the third losing record for the White Sox in eight seasons under manager Ozzie Guillen.
