SEATTLE (AP) — Kyle Seager slapped an opposite-field, bases clearing double for the big blow in Seattle’s seven-run sixth inning, and the Mariners avoided a sweep with an 8-4 win over the Chicago White Sox. Seager had three hits and his two-out liner down the left field line cleared the bases as the Mariners posted their highest scoring inning of the young season. Taylor Trammell, J.P. Crawford and Jose Marmolejos all had RBI singles in the inning and Mitch Haniger added a sacrifice fly.  Chicago starter Dallas Keuchel pitched into the sixth before being replaced. Seattle starter Justin Dunn walked eight batters and failed to finish the fifth.
