In this article, we will formulate a Mariners vs Red Sox prediction for this MLB game on Monday, June 16, at T-Mobile Park in Seattle, Washington. Let’s take a look at the prediction for this MLB matchup.
Boston Red Sox Betting Preview
The Boston Red Sox (37-36, 15-19 Away) defeated the arch-rivals New York Yankees twice in ten days, and they swept them in three games at home, thanks to Sunday’s 2-0 win. In between those series with the Yanks, the Red Sox beat the Rays. In Game 3, a 2-0 victory over New York, Rafael Devers scored a solo homer, which turned out to be his last for the Red Sox, as he was traded to San Francisco shortly after the game. Brayan Bello got the win after allowing no runs on three hits with eight strikeouts and three walks across 7.0 innings of work.
This year, the Red Sox average 4.84 runs per game (5th in the MLB) on a .253/.328/.422 triple-slash. When it comes to pitching, the Red Sox’s staff has a 3.96 ERA (17th) and 1.31 WHIP (21st). Jarren Duran leads the Red Sox with a .264 batting average, five home runs, and 38 RBI this season.
The projected starting pitcher for the Red Sox is Lucas Giolito, who is 2-1 in eight starts this season, with a 5.45 ERA and 1.54 WHIP in 39.2 innings.
Seattle Mariners Betting Preview
The Seattle Mariners (36-34, 19-17 Home) were on a three-series losing streak after falling to the Orioles, Angels, and Diamondbacks, winning just one of nine games and suffering two sweeps. However, the M’s responded with a sweep of the Cleveland Guardians. Seattle completed that sweep with a 6-0 victory on Sunday. J.P. Crawford blasted a grand slam off Luis Ortiz to lead his team, while Emerson Hancock got the win after allowing no runs on two hits with four strikeouts and one walk in 7.0 innings.
This season, the Mariners’ average 4.40 runs per game (12th in the MLB) on a .243/.323/.398 triple-slash. When it comes to pitching, the Mariners’ staff has a 3.96 ERA (18th) and 1.31 WHIP (19th). Cal Raleigh leads the Mariners with a .263 batting average, 26 home runs, and 54 RBI this season.
Logan Gilbert will take the mound for the Mariners on Monday. The 28-year-old right-hander has a 1-1 record in six starts this year with a 2.37 ERA and 0.79 WHIP in 30.1 innings.

Mariners vs Red Sox Prediction
The teams have traded victories in the past couple of years, each recording five in the previous ten H2H encounters. Seattle won two out of three games played in Boston earlier this season. Each of the Red Sox’s last five games went Under, as they significantly improved their defense. I expect another low-scoring affair on Monday, and the main reason for that is the return of Seattle’s ace, Logan Gilbert. Prior to his injury, Gilbert allowed more than two runs just once this season. Lucas Giolito, on the other hand, kept the opponents to below two runs in three of his previous four starts, and although he had one off game against the Angels, when he surrendered seven runs, I think Giolito will do just fine here. Go with Under.
