Career
Olaru was a successful junior player. She was the runner–up in both singles and doubles at the 2005 French Open, and captured the 2006 United States Open doubles title along with Mihaela Buzărnescu. Her best professional grand slam result so far has been the third round of the 2007 French Open, when she defeated the 30th seed Julia Vakulenko in straight sets and lost to eventual runner–up, the 7th seed Ana Ivanovic.
Olaru reached her highest singles ranking, World Number.
53, on 27 July 2009, and her highest doubles ranking, Number. 44, on 28 September 2015.
Olaru considers being a fighter as her biggest asset. She cites clay as her favourite surface and backhand down the line as favourite shot, but she can play well on all surfaces and she likes mixing up her game with drop shots.
Olaru is currently coached by former player Michael Schapers.
