For several hours before Rivera took the ball Saturday afternoon in that tie game, he’d suffered with a stomach ailment that brought aches and repeated vomiting, according to one Yankee. Rivera had rolled off the trainer’s table, where he’d hoped to sleep it off, and into the bullpen in the eighth inning, when he began to warm up. ...

“He was so upset afterward,” the teammate said.

And yet, Rivera did not mention it after the game, and he did not reveal it late Sunday afternoon, when it would have played less like an excuse than, in victory, the simple retelling of a trying 30 hours. He did not hang those hittable fastballs or that loss on his illness. He did not blame manager Joe Girardi for asking him to pitch in a tie game when a healthier body might have – and probably should have – done.
