This was exactly the type of game the Mariners needed: one that was pretty much over in the first inning.

The Mariners scored four in the first on homers by Jason Bay and a three-run blast by Michael Morse. And that enabled Aaron Harang to cruise to a complete-game shutout against the kind of NL club he got used to facing the majority of his career. It was his seventh career shutout and his first since April 12, 2009.

So, a 9-0 rout by the Mariners, who are now seven games under .500. They’ll take it for now, but they’ll have to keep on going after digging themselves a massive hole this past week.

Kelly Shoppach added a solo homer in the fourth inning — also off Padres starter Clayton Richard — and then the Mariners poured it on late off relief pitcher Anthony Bass in the eighth.

Nick Franklin got to make his MLB debut in the eighth inning at second base and immediate handled a leadoff grounder for a routine 4-3 out. Franklin then drew a leadoff walk in the bottom of the inning, the first Mariners rookie to do that in his debut plate appearance since Mike Carp in 2009.
