The play occurred in the sixth inning of Wednesday's 1-0 victory over the Twins, the resumed contest from the previous night's rain suspension. Joe Mauer scorched a line drive back through the middle, and the ball struck Robertson and shot right to A-Rod, who caught it on the fly for an out.
"It was scary at first, then it was funny," Yankees shortstop Derek Jeter said. "He didn't know Al caught it. He was looking all over the place. I mean, it wasn't funny until you saw he was OK."
Yankees manager Joe Girardi said that he was not planning on using Robertson in Wednesday's second game anyway. Robertson hurled 1 2/3 innings before yielding to Joba Chamberlain with a runner aboard in the seventh.
"He actually took the line drive off his back," Girardi said. "I've got to imagine, as the day goes on, he's going to stiffen up. I probably wouldn't use him anyway tomorrow. But he's OK."
