Rafael Nadal's early exit in the 2013 Wimbledon Championships headlines a group of shocking developments in the early going at the All England Club.
The two-time Wimbledon champion's first-round loss was something nobody saw coming, but it wasn't the only huge surprise in the first two days of action.
Major upsets occur every year during every Grand Slam event, but due to the extreme disparity between high- and low-seeded players, we're always caught off guard when it happens.
With this in mind, here's a closer look at the biggest eye-opening results from the early action at the All England Club.
Rafael Nadal Ousted in Straight Sets by Steve Darcis
Darcis is a career sub-.500 player who has won just two tournaments and is ranked No. 135 in the world—hardly someone you'd expect to knock off one of the world's premier players in a Grand Slam.
Yet that's exactly what Darcis did on Monday when he beat Nadal in straight sets, 7-6(4), 7-6(8), 6-4, on No. 1 Court at the All England Club.
For Nadal, it was his first career Round 1 loss in a Grand Slam event, as noted by ESPN Stats & Info, which also reported that it was the first time a French Open champ lost in Round 1 at Wimbledon in the same year:
Shock doesn't even begin to cut it—Nadal's early exit was something nobody saw coming, and it was the biggest surprise thus far at the All England Club.
Sara Errani Suffers Blowout Loss to Monica Puig
While Errani's loss wasn't quite as unexpected as Nadal's, it was certainly surprising.
The No. 5-seeded Errani was overmatched from the get go by Puig. The Puerto Rican teenager looked like she was the seasoned veteran and top-ranked player.
Puig broke Errani four times, smashing four aces and 38 winners in the process. Errani was helpless to stop the onslaught and lost in straight sets, 3-6, 2-6 to Puig, who won her first career Wimbledon match, as noted by the WTA:
Up next for Puig will be Silvia Soler-Espinosa, who got past Misaki Doi in three sets in Round 1.
Other Top-Seeded Players To Lose in Round 1
Nadal and Errani weren't the only top players to lose early. That said, they were the only ones whose losses were truly shocking.
On the men's side, Stanislas Wawrinka (11) lost to Lleyton Hewitt and Janko Tipsarevic (14) lost to Viktor Troicki.
On the women's side, Maria Kirilenko (10) was ousted by Laura Robson.
While all three of these results certainly fall into the "upset" category, it's not really a surprise at all that these higher-seeded players lost in the first round—all three have historically fared poorly at the Wimbledon Championships.
