In this Red Sox vs Royals Prediction, the Red Sox are coming as -115 road favorites. I like Sonny Gray more in this matchup, as he has given up just two runs across his last three starts, while on the other hand, Seth Lugo has given up 9 runs in his last two starts for the Royals. On top of that, the Red Sox have the 4th-best bullpen ERA to come after Gray, so everything points towards a win for the road team in this matchup. Take the Red Sox on the moneyline in a very good price.
