The Dodgers have designated lefty Zac Rosscup for assignment, per a club announcement. Taking his active roster spot is fellow reliever Casey Sadler. The swap clears a 40-man opening for the Los Angeles org.

Rosscup, 31, has traveled far and wide over the past several seasons. This year alone, he has appeared in the majors with three clubs. While he’s getting loads of swinging strikes, Rosscup is walking batters with alarming frequency (19 in 18 innings).

Sadler was added in a recent swap with the Rays that followed his own DFA. He has only made two appearances with the Dodgers’ top affiliate, allowing four earned runs in six innings but compiling nine strikeouts against one walk in that stretch.
