In this Angels vs Mariners Prediction, the Mariners are coming as -210 home favorites. I like the Mariners in this one with Kirby on the mound, as he has been the far better option than Ryan Johnson, who sits on an 8.84 ERA and 1.71 WHIP. Seattle also has a superior bullpen, ranking 7th in bullpen ERA, while the Angels are just 24th and have been bad on the road. Take the Mariners on the runline in this one.
