Marcus Semien lined a game-ending single into the left field corner to score Leody Taveras as the Texas Rangers rallied from a five-run deficit for a 6-5 win Sunday that kept the playoff-chasing Seattle Mariners from gaining ground in the AL wild card race.

The Mariners blew a five-run lead and, worse yet, blew a prime opportunity to gain traction in the American League playoff chase with a 6-5 loss to the Rangers.

Texas rallied with two runs in the bottom of the inning to pull to within 5-4, but the Mariners pulled away with three runs in the ninth against Walter Pennington, who allowed a double, a triple and a hit a batter left with two outs and two on before Rodriguez's two-run single against Gerson Garabito made it 8-4.
