Jake Mangum went 4-for-6 with two RBIs for the Tampa Bay Rays, who scored twice in the 11th inning to upend the host Boston Red Sox 10-8 in the opener of a three-game series on Monday night.

Red Sox starter Brayan Bello was later victimized by some sloppy defense in the fifth. Brandon Lowe drove in a run on a single that Jarren Duran dropped in left field, and the next batter up Diaz hit his liner under Anthony’s glove, putting the Rays up 3-0.

The Boston Red Sox called up Roman Anthony, baseball's consensus No. 1 prospect, Monday before beginning a six-game homestand.
