There's a class difference between these two teams. Given that and the starting pitching matchup, I'm going to back Tampa Bay at this short lay price.
The Rays' Ryan Yarbrough is a dependable starter. The Red Sox are likely to use this matchup as a bullpen game. That's fine if you have a good bullpen. The Red Sox don't.
Tampa Bay is 8-2 the past 10 times facing Boston. The Rays have won during each of their last four games in Boston.
