Cleavinger will play in the Arizona Fall League this year, Corey Seidman of CSN Philadelphia reports.
Cleavinger was acquired from the Orioles in the Jeremy Hellickson trade last month. He is 2-5 with a 6.18 ERA and a 58:30 K:BB in 51 innings between Double-A Bowie and Double-A Reading this season. The 2015 third-round pick needs to reduce his walks to become a more effective pitcher.
