Adrian Beltre hit a walk-off homer in the ninth inning, and the Texas Rangers kept Oakland from getting closer to clinching an AL wild-card spot with a 2-1 victory against the Athletics on Thursday night.
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.
The A's (86-73) lost a chance to clinch a wild-card spot when Seattle won at Toronto 7-5 earlier in the day in a game shown on the big video board in the Rangers' ballpark.
The last-place Rangers won for the 12th time in 13 games. The A's, who were swept by Texas in Oakland last week and started the day tied with Kansas City for the wild-card lead, have lost seven of 10.
Texas closer Neftali Feliz (2-1) pitched a scoreless ninth as the Rangers kept Oakland's magic number for clinching a third straight playoff spot at two.
