Tennis fans on Monday night were shocked as five-time US Open champion Roger Federer was ousted from the final Grand Slam of the year by Tommy Robredo.
The Swiss tennis ace has won a title every year since he won his first Grand Slam in 2003 and boasts of the most individual Grand Slam titles in the men's game with 17 titles.
The year 2013 has been dismal for Federer who has failed to make the finals of all four Grand Slams. Federer and old rival Rafael Nadal were set to renew their rivalry as they were set to clash in the quarter-finals of the US Open.
Federer's 7-6, 6-3, 6-4 loss in the third round means Nadal who faced a first set hiccup against German Philipp Kohlschreiber and then came back strong to win the match 6-7(4) 6-4 6-3 6-1 will now face compatriot and Federer-slayer Robredo for a place in the semi-final.
Nadal is seeking his second US Open title and is so far unbeaten on the hard court this season.
Roger Federer's loss means he is not ensured an ATP Finals place and may not feature in the season ender. Though in 2011 he didn't win any slams, the Swiss ace won the ATP Tour ender and made Grand Slam finals.
Since Juan Martin del Potro fell before him the former World No1 will rise to World No6 from 7 this week.
The 17-time-Grand Slam winner will need to reassess his career after this season that sees him have zero Grand Slam titles. The decision to hang his racquet or play on will depend on Federer's hunger for more wins and fitness.
