Aaron Harang threw a four-hitter, Jason Bay hit his first career leadoff homer and Michael Morse added a three-run shot as part of Seattle's four-run first inning as the Mariners beat the San Diego Padres 9-0 on Monday.

Harang (2-5) rebounded from a poor last start against the Angels, allowing a leadoff bloop double to Everth Cabrera and then retiring 18 of the next 19 batters. It was his first complete game since June 4, 2009 and first shutout since April 12, 2009. He struck out a season-high eight and threw 122 pitches.

A day after getting the game-winning hit in the 13th inning against Texas that snapped the Mariners' eight-game losing streak, Bay got Seattle started against San Diego lefty Clayton Richard (0-5).
