Red Sox-Mets Same Game Parlay Options

For all the flak they have been getting this season, the Red Sox have been actually solid when it comes to pitching with an Earned Run Average of 3.79 and that could be the foundation that keeps them competitive versus the Mets here. Although we expect Ceddane Rafaela and Willson Contreras to make their presence felt offensively here, the focus should be on starting pitcher Sonny Gray who has been giving opposing teams the work as of late.

Across 10 games pitched this season, the 36-year old Gray has won nine games and what’s even more impressive is the fact that he has recorded an ERA of 2.69 in those appearances. With the Mets being prone to swing-and-misses in stretches, the 5+ strikeouts contract on Gray is something worth considering for your Kalshi same-game parlay.

Other than that, we are also liking the Contreras RBI contract here although the Rafela hits contract is something worth considering given how he brings a more consistent at-bat profile that isn’t as dependent on runners in scoring position. What we are confident though is the Red Sox should walk away with a solid road win here even if the game doesn’t fully open up offensively, especially when you consider how the Mets have struggled against top pitching teams.
