US Open Moments: Sept. 14, 2009

On Sept. 14, 2009, Juan Martin del Potro, a 20-year-old from Argentina playing in his first Grand Slam final, came back from two-sets-to-one down to defeat five-time defending champion Roger Federer, 3-6, 7-6(5), 4-6, 7-6(4), 6-2, in a riveting final that lasted four hours, six minutes.

It marked the first five-set final since 1999 and the first to run longer than four hours since 1988. The loss snapped Federer’s 40-match US Open winning streak and denied the Swiss, who was two points from victory at one juncture, the honor of becoming the first man in the Open era to win the same Grand Slam event six consecutive times.

With the win, the 6-foot-6 del Potro became the tallest man ever to win a Grand Slam tournament.
