## Playing style

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.

## Sponsorships

Between 2006 and 2016, Cîrstea was sponsored for clothing, apparel, and footwear by Adidas; since 2016, she has been sponsored by New Balance. Cîrstea has used numerous racquets throughout her professional career – until 2014, Cîrstea used Wilson racquets, specifically endorsing the Wilson Blade range of racquets. In 2015, Cîrstea used the Babolat Pure Strike racquet, before switching to the Pure Aero model between 2016 and 2019. Cîrstea later switched to the Yonex EZONE 100 racquet in 2019, and is still using this racquet currently.
