The 2012 French Open is two days deep, and plenty of exciting action has already ensued.
Let's take a look at most shocking results of the first two days.
Andy Roddick Eliminated
Did Roddick's loss surprise you?
Roddick was defeated by Nicolas Mahut on the tournament's first day. This is not particularly surprising to fans of American tennis, but Roddick is still a prominent tennis name.
It took Mahut four sets to eliminate Roddick from French Open contention. He neutralized Roddick's serve and took advantage of his otherwise-inconsistent game.
Roddick is notorious for choking on the Grand Slam stage, but this upset is a surprise nonetheless.
This upset came on the tournament's first day, but it could be one of the tournament's biggest surprises when all is said and done.
Radek Stepanek Upset
Stepanek was defeated in five sets by David Goffin on Sunday. Stepanek was the No. 23 seed for men's singles.
Stepanek's loss to Goffin is definitely surprising, but not more shocking than Roddick's devastating defeat. He lost in five sets to an above-average defender, but Roddick lost to a lesser talent.
Goffin is not expected to advance past the second round, but his first-round victory is a pleasant surprise for the Belgian player.
Bethanie Mattek-Sands Advances
Mattek-Sands gave American tennis fans something to cheer about with her first-round upset over Sabine Lisicki.
Mattek-Sands won the match in straight sets.
She has never advanced further than the third round in the French Open, so this first-round match is a big boost to her confidence.
Lisicki was a not one of the tournament's top seeds, but she was expected to win this first match. Mattek-Sandds surprised everyone by sending her packing.
