Mariano Rivera’s appearance on Thursday in The Bronx was the last of his career. “I’m done” Rivera said before the Yankees faced the Astros Saturday at Minute Maid Park. Manager Joe Girardi said earlier he would give Rivera the option to change his mind and play Sunday but Rivera erased any doubt. “I gave everything that I have” Rivera said adding he didn’t want to pitch in a game that had no bearing on the standings. “I was playing for something. I’m not going to play just to play.” That also includes the possibility of him playing in center field something Rivera and Girardi had hinted at before the trip but Rivera didn’t want to take a risk with his surgically-repaired right knee. “I did consider it strongly” Rivera said. “If it would have been a few years earlier then I would have done it. But now my knee is not cooperating. I’m not going to make a fool of myself out there. I respect the game too much for me to do something that I’m not supposed to be doing.” So the emotional sendoff at Yankee Stadium when Rivera was taken out of the game by Andy Pettitte and Derek Jeter will be his final outing of his career. “I think Thursday was the day that I left everything on the field” Rivera said. “I was I won’t say hurt but sore. I was pitching with a tremendous soreness in my arm.” When pressed about how his arm felt Rivera said he had been dealing with a forearm issue.
