BOSTON — Rusney Castillo and Christian Vazquez each hit his first major league homer, and Allen Webster pitched seven solid innings to carry the Boston Red Sox to an 11-1 win over the Tampa Bay Rays on Thursday night.

Vazquez finished with a career-best four hits and drove in three runs, and Mookie Betts had three of Boston’s 16 hits. The Red Sox won for the fourth time in six games.

Evan Longoria had two singles for the Rays, who lost for the fifth time in seven games.

Webster (5-3) was charged with one run and seven hits in his best start since he joined the rotation in late July. The 24-year old rookie right-hander struck out five and walked one.

Leading 3-1 in the third, the Red Sox broke it open by scoring four times while chasing Jeremy Hellickson (1-5).

Yoenis Cespedes and Allen Craig had one-out singles before Garin Cecchini reached on first baseman James Loney’s error, with Cespedes scoring on the play. Steve Geltz then came in and Castillo drove the reliever’s first pitch into the front row of Green Monster seats for a three-run shot.

Hellickson lasted just 2 1-3 innings, getting tagged for six runs – five earned – and eight hits.

Vazquez’s two-run homer bounced off a billboard above the Monster, lifting the Red Sox to a 3-1 lead in the second.

Daniel Nava’s sacrifice fly gave Boston a 1-0 edge in the first before Ben Zobrist’s RBI single in the second tied it.
