Two unstoppable forces collided in this 2008 match-up at New York's Madison Square Garden. While a sold-out crowd watched in awe, two of tennis's biggest champs--Pete Sampras and Roger Federer--battled it out for victory. Though a decade may have separated them in age, the older Sampras still showed he could deliver the goods on the court. The tense game may have ultimately ended in Sampras's defeat, but it nevertheless showed he wasn't willing to give ground without a fight. This historic game is presented here in every second of its glory.
