Seattle is in near must-win territory here at home trailing by three games for a wild-card berth. I see value to the Mariners opening as underdogs with Hisahi Iwakuma pitching.

Iwakuma had a solid first four months before an August slump. He's back on track now allowing three earned runs in his last two starts spanning 13 innings. Seattle is 8-2 in his last 10 starts at Safeco Park and 15-7 in his last 22 overall starts. Iwakuma is 4-1 career-wise versus Toronto with a 2.50 ERA.

The Mariners have won 13 of 16 times as a home 'dog this season.

Toronto is favored because J.A. Happ is on the mound. He's having a career-year, but regression is due. He's also 0-2 in his starts at Seattle. Current Mariners are batting .330 against Happ.
