The Cubs claimed right-handed pitcher Cory Mazzoni off waivers from the Padres on Monday and assigned outfielder Leonys Martin outright to Class AAA Iowa.
Martin was a member of the Cubs postseason roster.
Mazzoni spent most of the 2017 season in the minors, combining for a 2-0 record with one save and a 0.59 ERA in 23 relief appearance. The 28 year old also spent a short amount of time in the big leagues. Mazzoni made six relief appearances for the Padres, posting a 13.50 ERA (12 ER/8.0 IP).
The Cubs acquired Martin from the Mariners on Aug. 31, 2017. He batted .154 (2-for-13) with one double and one RBI in 15 games with the Cubs.
The Cubs 40-man roster now stands at 34 players.
