Sorana Mihaela Cîrstea (Romanian pronunciation: [soˈrana ˈkɨrste̯a]; born 7 April 1990) is a Romanian tennis player. In singles, she achieved a career-high ranking of world No. 21, on 12 August 2013. In doubles, her career-high ranking is No. 35, which she reached on 9 March 2009. Her biggest achievements: reaching the quarterfinals at the 2009 French Open and the final at the 2013 Rogers Cup. Over her career, Cîrstea has defeated 13 Top 10 players: Anna Chakvetadze, Sara Errani, Jelena Janković, Angelique Kerber, Petra Kvitová, Li Na, Karolína Plíšková, Francesca Schiavone, Samantha Stosur, Caroline Wozniacki, Vera Zvonareva, Johanna Konta and Venus Williams. Cîrstea is an aggressive baseliner, whose game centers around her quick, flat, and powerful groundstrokes. As a result of her high-risk game style, she typically accumulates high numbers of both winners and unforced errors. Her backhand is her most reliable groundstroke, and she consistently hits winners with this shot, and, even when she does not aim specifically for the lines, her backhand penetrates deep into the court, allowing her to dictate play. Her forehand is hit very flat, allowing her to hit deep into the court with regularity, generate consistent power, and hit a large numbers of winners; her forehand is somewhat erratic, however, meaning that unforced errors do accumulate from this wing. Cîrstea is capable of generating sharp angles off both sides, producing winners. According to the Tennis Spy, her long stride means she covers ground while not appearing to move particularly quickly, allowing her to execute her game style excellently. As a doubles player, she is also a very solid volleyer, and likes to attack short balls with powerful swinging volleys. Her first serve is powerful, peaking at 109 mph (175 km/h), allowing her to serve aces and dictate play from the first stroke, however a tendency to take risks on her second serve does lead to an accumulation of double faults when nervous.

Martincová has won four singles titles on the ITF Circuit. On 1 November 2021, she reached her best singles ranking of world No. 48. On 27 September 2021, she peaked at No. 188 in the WTA doubles rankings. In June 2013, Martincová made her WTA Tour main-draw debut at the Nürnberger Versicherungscup. After coming through all three qualifying rounds, she lost to Estrella Cabeza Candela in round one. One month later, Martincová once again came through qualifying at the Baku Cup, defeating Oksana Kalashnikova in the first round, but losing to Tadeja Majerič in the second.
