History was made at the National Bank Open in Toronto, as Jessica Pegula became the first woman to win the event back-to-back since Martina Hingis in 2000. The American star defeated her compatriot Amanda Anisimova in a thrilling three-set final, after overcoming two former college players, Peyton Stearns and Diana Shnaider, in the quarterfinals and semifinals respectively. Pegula, who has reached a career-high ranking of No. 3 in the world, has an impressive 17-2 record at the Canadian tournament.

But what were the key factors that propelled Pegula to her second consecutive title in Toronto? How did she dominate her opponents from the quarterfinals onwards? Here are some of the data points that reveal her success story.

Serve & Return

Pegula’s serve was a formidable weapon throughout the tournament, but especially in the last three matches. She held 88% of her service games, while breaking her opponents 33% of the time. She faced only 10 break points in three matches. She also won 74% of her first serve points, and 64% of her second serve points. Her opponents were not getting very many chances to play their way into return games, and when they did put some pressure on her service games, Pegula came up with the quality serves.  Under pressure, she was even more effective on defending her second serve, winning 70% of those points. Her opponents had no answer to the power and placement of her serve, which gave her a huge advantage in the matches.

Rallies

Pegula also controlled the rallies with her aggressive play and smart decision-making. 90%  of the points lasted 8 shots or less, with Pegula winning 55% of those points. She also excelled in the longer rallies, winning 69% of the points that lasted 9 shots or more. She was able to dictate with depth &  pace on her rally balls, keeping her opponents in the corners and playing defense.
