The Marlins designated reliever Jon Rauch for assignment following Friday's loss and called up left-handed pitcher Duane Below from Triple A New Orleans.
Rauch entered Friday's game in the eighth inning, but failed to retire any of the four batters he faced in the ninth before being taken out for Ryan Webb. In 15 appearances for the Marlins, Rauch went 1-2 with a 7.56 ERA. Rauch was charged with two runs in the 9-2 loss.
Below, a left-hander, was claimed not long ago by the Marlins from the Detroit Tigers, where he spent parts of two seasons, going 2-3 with a 4.06 ERA in 41 appearances, including three starts.
Below had been starting at New Orleans, where he was 2-2 with 3.38 ERA in four starts.
