The Mariners have been playing well lately but they always seem to struggle behind Yusei Kikuchi. He is 1-3 with a 6.35 ERA in his last 7 games and he is worse at home going 2-4 with a 4.65 ERA. Brad Keller has been pitching much better lately having pitched quality starts in 6 of his last 8 games. Both these teams have actually won 7 of their last 10 games, so I think this should be much closer to a toss up. Take the value in the Royals.
