Romanian world number one Simona Halep beat American Sloane Stephens in three sets to win the Rogers Cup in Montreal.

Halep, who beat Stephens in the French Open final in June, eventually came out on top 7-6 (8-6) 3-6 6-2.

Halep took a dramatic first set in a tie-break after three breaks of service apiece, but lost the second before recovering in the decider.

Meanwhile, unseeded Stefanos Tsitsipas, on his 20th birthday, is playing Rafael Nadal in the men’s final in Toronto.

Halep, who also won the Rogers Cup in 2016, emerged victorious after a marathon encounter lasting two hours and 41 minutes in sweltering conditions.

Both players were regularly doubled up, struggling for breath, amid some punishing rallies in the gruelling heat.

“I just didn’t give up during the tournament, I fought until the end,” said Halep.
