Wimbledon 2013 has seen its share of shocking upsets, and Agnieszka Radwanska is one of the contenders who will come up short as the tournament moves forward.
No. 4 Radwanska (POL) is one of the few top players left in the field, but not even she will be able to take advantage of the upsets.
Earlier on Monday, No. 1 Serena Williams (USA) was defeated by No. 23 Sabine Lisicki (GER) in three sets (recap courtesy of Wimbledon's official website).
Williams joins Victoria Azarenka (BLR), Maria Sharapova (RUS) and Sara Errani (ITA) as favorites who have been knocked out early.
This tournament has been as unpredictable as ever, so nobody should be shocked if an underdog wins the title.
Here are some contenders who will fail to win Wimbledon this year.
No. 4 Agnieszka Radwanska (POL)
Radwanska will have a tough matchup against Na in the quarterfinals, so it's looking like Radwanska will be exiting the tournament soon.
It will be an intense match, but Na will have the edge.
Na currently owns a 6-4 edge in her career against Radwanska, and she has done very well in recent meetings. She won the most recent meeting and has won four of the last five meetings.
The two players have met twice at Wimbledon, and Na won the most recent match. They have played only three times on grass, but Radwanska has won two of those meetings.
They haven't played on grass in three years, so Radwanska hasn't been able to prove that she can dominate Na on the surface.
Playing on grass is the only chance that Radwanska has. The recent meetings favor Na, so it would be a surprise if Radwanska could get past her rival.
No. 15 Marion Bartoli (FRA)
Marion Bartoli has not lost a set at Wimbledon this year, but she is going to suffer a disappointing exit.
Bartoli defeated Sloane Stephens, her opponent in the upcoming quarterfinals, in their only previous meeting. She would also have to get past No. 8 Petra Kvitova in the semifinals, so the road is not easy for Bartoli.
She does hold the edge over her next two opponents throughout her career, but that's not going to matter. This year's Wimbledon has been shocking.
With Bartoli cruising through first four rounds, she could be poised to fall to Stephens in the quarterfinals. If she gets past the rising star, Bartoli would have to find a way past Kvitova and Na.
No. 23 Sabine Lisicki (GER)
Lisicki had the biggest win of the tournament when she knocked off Williams 6-2, 1-6, 6-4. That win put her in the mix as a contender.
She has defeated No. 1 Williams and No. 14 Samantha Stosur (AUS) in back-to-back matches. Unfortunately she won't be able to carry the momentum throughout the rest of the tournament.
The 23-year-old has come out of nowhere in this tournament. She has never made it out of the semifinals of any Grand Slam tournament. She has made the quarterfinals at Wimbledon in three out of four years, including the semifinals in 2011.
Lisicki has had a great run in this year's Wimbledon. She has lost only two sets, one to each Williams and Stosur, but she has gotten past some tough competition.
After a pair of big wins, she is done sneaking up on her competition.
