In the first big upset of the 2012 U.S. Open, No. 5 seed Jo Wilfried Tsonga of France was upset in his second round match by Martin Klizan of Slovakia in four sets 6-4, 1-6, 6-4, 6-3.
The 27-year-old Tsonga, one of the most talented and enigmatic players in men's tennis, had seemingly overcome his inconsistency in major tournaments over the last few years, as he regularly advanced deep into the quarterfinals and semifinals of all four majors.
Something was off on Thursday, however, as Tsonga would up going home with his earliest exit in a major since the 2007 Australian Open.
After coming out flat in the first set, he seemingly rebounded in the second, before repeated unforced errors in the third and fourth capsized him.
His loss opens up his side of the bracket and may make the road to a U.S. Open title easier for Andy Murray, the No. 3 seed, who was slated to face Tsonga later in the draw.
