Australia Tennis Open, 2005, final match - Courier and Sampras
De TENNIS; Brawn, Sweat and Tears: Sampras Storms Back (The New York Times):
Sampras had worn himself into an emotional frazzle worrying about the health of his coach and best friend, Tim Gullikson, who spent the weekend undergoing tests in a private hospital after apparently suffering the latest in a series of strokes linked to a congenital heart ailment, which was first diagnosed in December.
It wasn't until Sampras took his first lead of the match by holding serve to start the fifth set that his emotions floored him. He sat down for the change-over and, with his shoulders heaving and his face buried in his towel, he burst into uncontrollable tears. He struggled through the next two games, then called the trainer over to help talk him through his distress.
Sampras had appeared on the verge of giving up the match, but instead he soldiered on, broke Courier in the eighth game, and converted his first match point when Courier's forehand return soared long.
