ST. PETERSBURG, Fla. (AP) — The sliding Tampa Bay Rays couldn't recover from an early eight-run deficit. Rookie Mookie Betts hit his first career grand slam, Anthony Ranaudo pitched six effective innings and the Boston Red Sox beat the Rays 8-4 Friday night. The Rays have lost nine of 13. After Yoenis Cespedes drove in his second run of the game with a double, Betts connected off Chris Archer (8-7) to cap a five-run second inning that made it 8-0. "I didn't execute many pitches," Archer said.
