Boston Red Sox vs Seattle Mariners Moneyline

The Red Sox and Mariners are closely matched with their records, but Seattle’s home field advantage could sway the moneyline odds. With Boston missing key players like Alex Bregman, this matchup presents opportunities for bettors to consider the shifting dynamics in play.

Boston Red Sox vs Seattle Mariners Run Line

The Boston Red Sox, with a 36-36 record, face the Seattle Mariners at T-Mobile Park. Given the current run line, Boston could struggle to cover without Alex Bregman, who is out with an injury. Seattle’s home advantage and recent performance might just keep this game close enough to challenge the spread.

Boston Red Sox vs Seattle Mariners Over/Under

The Red Sox and Mariners have combined for an average of 7.8 runs in their last five meetings, indicating a solid offensive matchup.
