Chris Young is 7-3 at home this season with a 2.42 ERA. He is one of the most underrated pitchers in baseball as proven again by being a short home favorite against southpaw J.A. Happ, who has an ERA above 4.00. The Mariners are 25-15 versus lefties.

Toronto has lost 7 of its last 10 and Happ is coming off a 125-pitch effort in his last start. Seattle has the superior bullpen and its rested. The Mariners are swinging hot bats, too, averaging 6.2 runs in their last seven games. Toronto, by contrast, has scored two runs or less during each of its last 4 road games.

The Blue Jays are missing three of their top hitters as Edward Encarnacion, Bret Lawrie and Adam Lind are all out.
