Marlins promote prospect Joe Mack in catching shakeup

The Miami Marlins called up top catching prospect Joe Mack on Monday and optioned fellow backstop Agustin Ramirez to Triple-A Jacksonville.

Mack hit .244 with three home runs and nine RBIs in 24 games at Triple-A, while Ramirez, 24, was batting .230 with two homers and 14 RBIs in 31 games this season with the Marlins.
