Most Surprising Results From Day 1
Monica Puig Defeats Sara Errani (5)
Those who follow the sport of tennis closely may not have been too shocked to see Errani lose in Round 1 of this year's Wimbledon, but it's always a surprise when a top-ranked player is ousted so soon.
Errani lost in the first round last year, and she's never gotten out of the third round at the All England Club in her six Wimbledon appearances.
Puig dominated her match against Errani. She scored four aces, hit 38 winners to Errani's 13 and had Errani running wild throughout the match.
The Puerto Rican teenager has not yet won a single event on the WTA Tour. This was her first Wimbledon, and thus far she's made the most of it.
Steve Darcis Defeats Rafael Nadal (5)
In the most surprising match of the day—nay, the year—Nadal lost to an unheralded veteran who had only won two matches before this one in 2013.
Darcis—the No. 135-ranked player in the world—looked like Pete Sampras on the grass court at the All England Club on Monday.
The Belgium-born player outplayed Nadal in every facet of the game and punished the King of Clay with powerful serves and a brilliant display of shotmaking from everywhere on the court. He landed 13 aces, blasted 53 winners and won three break points in his improbable victory.
For Nadal, this loss will certainly be a huge disappointment after his stellar return. As ESPN Stats & Info noted, it was Nadal's first career Round 1 loss in a Grand Slam:
For Darcis, his adventure is just getting started. He'll take on Lukasz Kubot in Round 2 to fight for a chance to move on in the brutal bottom half of the men's draw at Wimbledon.
