The Baseline

- Diatchenko is into the second round of a Grand Slam for just the third time in her career and for the first time ever at Wimbledon. She lost in the first round in each of her previous two trips to London in 2011 and 2015. Her two wins at majors both came on the red clay of Roland Garros, in 2015 against Stefanie Voegele and in 2009 against Mathilde Johansson. 

- The Russian came through three rounds of qualifying to reach the main draw. After dropping just two games to Britain's Samantha Murray in the first round, she needed three tough sets and almost two-and-a-half hours to beat Ankita Raina of India in the second round. Diatchenko earned her place in the 128-player field with a win over another Russian, Sofya Zhuk, 6-2, 6-2, last Friday.

- The victory over Sharapova was just Diatchenko's second against a Top-50 player. In 2014, she defeated world No. 14 Dominika Cibulkova at a hard-court tournament in Moscow. 

- Diatchenko has won one career WTA tour singles title, at a 125K in Taipei in 2014, and one doubles title, at Tashkent with Eleni Daniilidou in 2011.

- The right-hander was ranked as high as No. 71 in the world in November 2014. An accomplished doubles player, she was once the No. 60-ranked doubles player in the world in February 2011. She came into Wimbledon at No. 132 in the world, having started the season at No. 188. At the end of 2016, Diatchenko was as low as No. 553.

- The 27-year-old played three grass-court tuneup matches heading into Wimbledon after losing in the second round of the French Open qualifying tournament. She beat American Jennifer Brady in the first round of an ITF-level tournament in Manchester, England, before losing to Marie Bouzkova. The following week, she was forced to retire in the second set of her first-round qualifying match in Mallorca, Spain.
