The Mariners pitching staff wasn't able to stifle the Red Sox offense in the first game in the final leg of the road trip.

Brayan Bello will start for the Boston Red Sox on Tuesday against Randy Arozarena and the Seattle Mariners. First pitch is at 6:45 p.m. ET for this first game in a three-game series. The Red Sox's 4.04 team ERA ranks 15th across all league pitching staffs. Mariners pitchers have a combined ERA of 3.78 ERA this year, which ranks 12th in MLB.

Boston won the series-opener behind five strong innings from Brayan Bello (four hits, one earned run allowed), plus two hits and three RBIs from Alex Bregman. Seattle is 4-3 on this 10-game road trip and has yet to lose back-to-back games on the trip.
