The 2012 US Open has provided everything that a Grand Slam should provide—fascinating matchups, heart-stirring victories and unpredictable upsets.
We've already seen plenty of all of those so far at Flushing Meadows this year—particularly upsets, which have both shocked and surprised both because of who was eliminated and who sent them packing.
Here are the most surprising results that have blown the field open so far at the 2012 US Open.
Former World No. 1 Caroline Wozniacki is always a tough competitor in Grand Slam tournaments—even if she cannot seem to claim the overall victory—and was expected to wipe the floor against her unknown Romanian opponent in the first round.
It wasn't even close.
Irina-Camelia Begu wins 6-2, 6-2
Currently ranked 88th in the world and having never made it past the second round at a Grand Slam tournament in three years, Great Britain's Laura Robson had already achieved a personal best when she progressed through to the third round at the 2012 US Open.
She was up against Li Na—a Grand Slam champion—and current ninth seed for this tournament, and in a long, tough match, Robson prevailed in the third set to book her place in the final 16 of the competition.
Laura Robson wins 6-4, 6-7, 6-2
Florian Mayer entered the tournament with somewhat of an outside chance at success, but as the 22nd seed, was still expected to be around in the third and fourth rounds of the competition.
Especially when he drew the World No. 243 in the first round, Jack Sock.
Mayer retired injured halfway through the third set, after the American had clinched the first two sets.
Jack Sock wins 6-3, 6-2, 3-2 ret.
Guillermo Garcia-Lopez has been ranked as high as 23rd in the world before, but came into the 2012 US Open ranked outside of the top 60 players and was supposed to be an easy-beat for the No. 10 seed, Juan Monaco.
After taking the first two sets, Monaco looked in complete control and should have clinched the match, but he allowed his Spanish opponent back into the match—failing to win 20 break point opportunities—and would eventually lose in five sets.
Guillermo Garcia-Lopez def. Juan Monaco: 3-6, 1-6, 6-4, 7-6, 7-6
Considered by many to be the man most likely to break up the Big Four in the men's field—Novak Djokovic, Roger Federer, Rafael Nadal and Andy Murray—Tsonga is always a genuine threat in Grand Slam tournaments.
The absence of Rafael Nadal confirmed that status, and heading into his second round match against Slovakian Martin Klizsan, the Frenchman was expected to simply wipe the floor with his opponent.
Martin Kliszan def. Jo-Wilfried Tsonga 6-4, 1-6 ,6-1, 6-3
