Seattle Mariners vs Boston Red Sox Prediction & Picks - MLB

Prediction published on 6/16/25, 6:23 PM  by Carlos Zabala | Modified on 2/11/26 at 8:28 AM in MLB Picks

Without a break, the Red Sox head to T-Mobile Park for another week of MLB action in a new series against the Mariners. They've done so on a very high note in recent games, having won 5 of 6 against their bitter rivals, the Yankees, in New York and at Fenway Park. In between those two series, they also won another one against the Rays.

The Red Sox won Sunday's game 2-0 behind a superb performance by Brayan Bello, who pitched 7 scoreless innings and struck out 8. Devers hit his 15th home run of the season off a Max Fried pitch, and that RBI, along with another by Story, was enough to give the Yankees left-hander his second loss of the season.

The Red Sox have won five straight, but the Mariners have a three-game winning streak after sweeping the Guardians, atoning for their loss to the Diamondbacks in Arizona.

The tentative pitching matchup is Lucas Giolito for the Red Sox against Logan Gilbert for the Mariners.
