Yankees closer Mariano Rivera is suffering from some shoulder soreness and was not available for Sunday's game against the Angels, according to The New York Daily News. He felt spasms and soreness between his shoulder blades after pitching against Los Angeles on Friday night, and the issue flared up on Sunday again. "I felt it on Friday and I really didn't pay attention to it," Rivera said. "(Sunday), I was stretching and I felt discomfort there and they decided to shut me down." Rivera's status for the start of New York's series against Texas on Monday is not yet known.
