ARLINGTON, Texas (AP) The Oakland Athletics lost a chance to clinch their third straight trip to the playoffs before their game in Texas started.
Yet another loss to the last-place Rangers kept the A's from at least getting a little closer to one of those AL wild-card spots.
Adrian Beltre hit a walk-off home run in the ninth inning for Texas' 12th win in 13 games, and Oakland's magic number for clinching the postseason remained at two with a 2-1 loss Thursday night.
The A's (86-73) already knew they were going to have to wait at least another day to celebrate when Seattle won at Toronto 7-5 in an afternoon game shown on the big video board in the Rangers' ballpark.
Their seventh loss in 10 games dropped them out of a tie for the wild-card lead with Kansas City, which beat the Chicago White Sox 6-3. With three games left, the A's still need a combination of Oakland wins and Seattle losses totaling two in order to clinch.
''They're all different, but the common denominator is we're not scoring any runs,'' said Oakland manager Bob Melvin, whose team was swept by Texas at home last week. ''We're getting opportunities to do it and we're still not getting them in.''
Beltre sent a drive just over the wall in right field off Luke Gregerson (5-5) with one out for his team-leading 19th homer of the season and just his second since Aug. 10. It was the first walk-off homer of the season for the Rangers.
Texas closer Neftali Feliz (2-1) pitched a scoreless ninth.
''It's been fun,'' said Beltre, who dodged one dousing during an on-field interview but couldn't avoid a drenching from a second bucket. ''We've been playing very well.''
Oakland's Coco Crisp reached base five times on two singles and three walks, but Josh Reddick went 0 for 5 behind him and never moved him up to second base.
The A's put the leadoff runner on five times in seven innings against Colby Lewis, but he pitched around five walks and six hits with seven strikeouts.
With his season-ending no-decision, the 35-year-old Texas right-hander coming off partial hip replacement surgery ended up tied with Japanese ace Yu Darvish for the team lead with 10 wins.
''We talked all season about how inspirational he is,'' Texas manager Tim Bogar said. ''It was fun to watch Colby go out there and fight through that and get through seven innings.''
Jason Hammel made his first start for Oakland since the birth of his second child over the weekend in Massachusetts. He had a one-hitter in the sixth when Leonys Martin reached on a bunt single with two outs, stole second and scored on Elvis Andrus' single for a 1-1 tie.
The right-hander, just 2-6 since coming over from the Chicago Cubs in a trade at the deadline, was replaced after allowing consecutive singles to Beltre and Jake Smolinski to start the seventh. Dan Otero got two strikeouts to keep the Rangers from taking the lead.
''Sometimes you've got to make one run stand up and I didn't do that, so I'm pretty disappointed,'' Hammel said. ''It just stinks it's two little light hits that end up tying the ball game.''
FACING HIS OLD TEAM
Geovany Soto, playing at Texas for the first time since the Rangers traded him to Oakland a month ago, put the A's up 1-0 with a sacrifice bunt in the sixth. Brandon Moss held up at third until the bunt was down and scored easily.
Athletics: OF Brandon Moss is planning to have surgery following the season after an MRI revealed torn cartilage in his right hip.
Rangers: LHP Martin Perez, who had reconstructive elbow surgery in May, will start a throwing program in November at home in Venezuela. After a couple of trips back and forth, he'll return to Texas in January to get ready for spring training.
Athletics: LHP Scott Kazmir (14-9, 3.63) is 0-4 with an 8.58 ERA over his past six starts and has the second-highest ERA in the majors since the All-Star break.
Rangers: RHP Nick Tepesch (5-10, 4.14) has a 2.96 ERA in four September starts.
