BOSTON (AP) — Brayan Bello allowed one run over five innings in his season debut, Triston Casas hit a three-run homer in the seventh and the Boston Red Sox beat the Seattle Mariners 8-3 on Tuesday night for their sixth win in seven games.
Alex Bregman hit a pair of RBI doubles for the Red Sox.
Jorge Polanco hit a solo homer in the first for Seattle and J.P. Crawford hit a two-run single in the sixth as Seattle closed to 4-3.
Bello (1-0), who had been sidelined by a strained right shoulder, followed Polanco's homer with a walk and two hit batters before Rowdy Tellez grounded into a 3-6-1 double play.
