The Red Sox starter Brayan Bello doesn’t always record a quality start every time he gets the ball, but he has been consistent, getting the QS in eight of his last nine starts. He has one career start against the Mariners, and it was a mixed bag allowing just one run over five innings but allowing a season high five walks. The Mariners starter Bryce Miller had a rough out on the road in his latest getting tagged for six runs but has looked really good at home this season with a 2.70 ERA. I couldn’t get a five-inning line at the time of writing which would be my first choice, but there is value in taking the Under 7.5 game total.
