HOUSTON (AP) — Nick Franklin hit his first career grand slam in Seattle's big second inning to back up a scoreless start by Felix Hernandez, and the Mariners rolled past the Houston Astros 12-5 on Sunday for their season-best sixth straight victory.
Franklin's slam, Seattle's fifth this season, came off Jordan Lyles (4-4) in a seven-run second.
Hernandez (11-4) scattered four hits with seven strikeouts over six innings to lower his AL-leading ERA to 2.43. He is 6-0 in his last 10 starts and hasn't lost since May 25.
Brad Miller, Dustin Ackley and Michael Saunders drove in two runs each to help the Mariners wrap up a three-game sweep.
Lyles yielded eight hits and 10 runs, with a career-high nine earned, in four-plus innings to lose his third straight decision.
