Andy Murray put his hands over his face when it was over, then crouched down as Center Court roared. He quickly popped back up and went to the net to shake Roger Federer's hand.

One month after anguish at Wimbledon, it was elation in the Olympics — all in the same spot.

Roger Federer has "been around the block," as he puts it. He knows how to handle the big moments, playing for major titles, for the record books, for an exalted place in tennis history.

Sunday's Olympic gold medal singles match is something new even for him.
