Blue Jays-Red Sox Same Game Parlay Options

If this matchup happened maybe a month ago, then we wouldn’t have thought twice about backing the Blue Jays after winning five of their previous six meetings with the Red Sox this season. However, the Red Sox have completely turned things around, winning 14 straight games to put themselves in the playoff conversation.

Although the offensive exploits of Ceddane Rafaela and Willson Contreras have been steady throughout this winning run, it has been their pitching that has truly laid the foundation for their success. Starting pitcher Sonny Gray in particular, has given the Red Sox a reliable presence on the mound and we’re expecting him to record over 5.5 strikeouts here given his recent performances.

Other than that, we’ll also sprinkle in the Rafaela 2+ hits prop and an outright Red Sox win to complete our BetMGM same-game parlay. As much as we’d like to back the Blue Jays here, it's hard to go against a Red Sox team that has all the momentum at the moment and is quite frankly, playing its best baseball of the season.
