Mariners 9, Padres 0: Aaron Harang threw his first complete game shutout since 2009 to lead host Seattle to a win in the first of four straight against interleague opponent San Diego.

Harang (2-5) recovered from a miserable outing at Anaheim on Tuesday by yielding just four hits and striking out a season-high eight. He gave up a double to leadoff batter Everth Cabrera before retiring 11 in a row and holding San Diego without another hit until the seventh.

Jason Bay homered to lead off the bottom of the first and Michael Morse added a three-run shot later in the frame as the Mariners jumped all over Padres starter Clayton Richard (0-5). Kendrys Morales finished with three hits, including a two-run single in the seventh that made it 7-0.

Kelly Shoppach also homered and Raul Ibanez chipped in an RBI double for Seattle, which has won two straight since ending an eight-game slide.

Richard, who was reinstated from the 15-day disabled list for this start after an intestinal virus put him on the shelf, gave up five runs in six innings. He is winless in nine starts dating to Sept. 20.
