Maria Sharapova at the U.S. Open

Maria Sharapova enters the 2014 U.S. Open as the No. 5 seed in the women's draw. Her first-round opponent will be countrywoman Maria Kirilenko of Russia. Sharapova is in the opposite end of the bracket as No. 1 seed Serena Williams. 

Here is a look back at Sharapova's past performances at the U.S. Open.

Last year, Sharapova withdrew from the 2013 U.S. Open just before the start of the tournament, citing shoulder bursitis, but others believed it may have been the result of a lingering hip injury that occurred in Wimbledon earlier in the summer. 

Sharapova reached the semifinals of the 2012 U.S. Open for only the second time in her career, before falling to Victoria Azarenka.

Prior to the semifinals finish in the 2012 U.S. Open, Sharapova won the silver medal in the London Summer Olympics. 

The best finish for Sharapova in a U.S. Open tournament came in 2006, when she defeated Justine Henin-Hardenne in straight sets to win the tournament. It was the only time that Sharapova won the U.S. Open. 

On her way to the victory, Sharapova won Henin-Hardenne, No. 1 seed Amélie Mauresmo in the semifinals and Tatiana Golovin in the quarters. Sharapova entered the tournament as the No. 3 seed.

Sharapova's all-time record at the U.S. Open is 29-8. 

Since turning pro in 2001, Sharapova has missed just four U.S. Open tournaments. 

In her last five U.S. Open performances, Sharapova has made it out of the third-round just once, and that was in her 2012 semifinal appearance. Her worst finish in the past five years came back in 2010, when Sharapova fell to Caroline Wozniacki in the fourth round of the tournament.
