Australia's Lleyton Hewitt won an absorbing late-night thriller against sixth seed Juan Martin Del Potro at the US Open on Friday to move into the third round.
In a battle between the two former US Open champions, the veteran Australian came out on top after more than four hours, winning 6-4 5-7 3-6 7-6 (2) 6-1, in one of the biggest upsets of the tournament.
Del Potro, who stunned Roger Federer to win the 2009 US Open, was one of the favourites to win the men's singles title but the towering Argentine was unable to find an answer to Hewitt's counter-punches as the pair slugged it out like two heavyweight boxers.
''It was a hell of a lot of fun, I cherish every match I get,'' said the 32-year-old Hewitt, who won the US Open in 2001.
''This is why I still play, to have moments like this.''
