Two Rangers Minor League right-handers, Orlando Caraballo and Miguel Munoz, were suspended on Wednesday after testing positive for performance-enhancing substances under the Minor League Drug Prevention and Treatment Program.

Both players, members of the organization's Rookie Dominican Summer League team, tested positive for Boldenone and the suspensions are effective immediately. Caraballo, 19, received a 50-game suspension. Munoz, a 21-year-old who was also suspended on Sept. 17 of last year, received a 100-game suspension for a second violation.

Caraballo was 2-1 with a 1.56 ERA in eight relief appearances this summer. Munoz was 3-2 with a 3.62 ERA in eight games (four starts).
