The Boston Red Sox scored six runs in the top of the 10th inning to defeat the host Seattle Mariners 9-4 Wednesday afternoon and keep pace in the American League wild-card chase.

The Mariners (78-68) dropped four games back in their bid for their first postseason appearance since 2001.

Boston's Jack Lopez, who started the 10th as the runner at second base, advanced to third on a single by Alex Verdugo and broke a 3-3 tie by scoring on a passed ball.

With one out and the bases loaded, J.D. Martinez hit a run-scoring single off the glove of diving shortstop J.P. Crawford, Kyle Schwarber lined a two-run single to right field and Christian Vazquez blooped a two-run double down the first-base line.
