Kansas City Royals vs. Seattle Mariners Prediction
I’m on the Mariners in this one. I just think that this is a nice bounce back spot for Seattle as Hancock’s been solid this season and the Royals, while improved, just haven’t been able to back up Lugo in the majority of his starts this year, although they did in his last outing when Lugo gave up 7 runs. I think this will be a pretty good matchup but I like Seattle for the bounce back here. Give me the Mariners.
