Marlins designated RHP Jon Rauch for assignment. The veteran right-hander's short tenure with the Marlins comes to a close after just 16 2/3 innings. During that time, he compiled a 7.56 ERA, 1.80 WHIP and 15/7 K/BB ratio. Despite the poor start, Rauch should have no problem attracting interest from other teams starved for bullpen depth.
