Boston Red Sox place third baseman Pablo Sandoval on disabled list

Boston Red Sox third baseman Pablo Sandoval is back on the 10-day disabled list with a left inner ear infection after the former two-time All-Star and World Series MVP missed 31 games earlier this season with a right knee sprain.

Sandoval, 30, has been in and out of the lineup since he returned from his knee injury on May 31. Sandoval is batting just .212 with four home runs and 12 RBIs over 32 games this season.

In corresponding moves, the Red Sox recalled infielder Deven Marerro and first baseman Sam Travis from Triple-A Pawtucket. Right-handed relief pitcher Austin Maddox was also optioned to Pawtucket after Monday's game.

Marrero, 26, hit .157 with three homers and 11 RBIs in 33 prior games with the Red Sox this season. Travis, 23, made his major league debut with Boston on May 24 and is 8-for-17 (.471) at the plate in six big league games this year.

Maddox, 26, allowed one hit and struck out one over two innings in two relief appearances with Boston.
