Cubs' Mateo exits with injury

SURPRISE, Ariz. -- Chicago Cubs relief pitcher Marcos Mateo left Thursday’s game with apparent arm pain after facing one batter in the sixth inning. The Cubs said Thursday night that Mateo will have an MRI arthrogram on the arm.

Mateo was injured July 4 of last season, leaving a game against the Washington Nationals with right elbow soreness. He missed the rest of the season with the injury.

The Cubs’ coaching staff was questioned about their use of the young pitcher after they had Mateo throw 80 pitches in a five-inning relief outing on June 30. Mateo suffered the elbow injury his next time on the mound.
