Robertson day-to-day, not available Sunday
NEW YORK -- Dave Robertson will not be available for the Yankees on Sunday, one day after he had to leave an appearance with tightness in his lower back.
"He's down today. He's day-to-day," Yankees manager Joe Girardi said. "He doesn't feel terrible today, but I won't use him and see how he is tomorrow."
Robertson said that he never had a bruise from the hard liner that Joe Mauer smoked off his back on Wednesday, saying that his belt -- which still has the seams from where the ball impacted it -- took the brunt of the damage.
"It's right above that, so I'm guessing that ball he hit off me probably had a little something to do with it," said Robertson, who is wearing a heat pack on his back to keep it loose.
