Simona Halep strengthened her position as women’s world number one following her latest tournament triumph, according to the WTA rankings released Monday.

The 26-year-old from Romania leads her nearest rival, Caroline Wozniacki of Denmark, by a margin of more than 1,000 points following her win on Sunday in Montreal.

The French Open champion beat world number three Sloane Stephens 7-6 (8/6), 3-6, 6-4 in a gruelling 2 hour 41 minute battle.

Greek 20-year-old Stefanos Tsitsipas broke into the world top 20 on Monday following his giant-killing run at the Toronto Masters.

The beaten finalist who lost out to world number one Rafael Nadal on Sunday vaulted into 15th place a day after his 20th birthday.

Tsitsipas, ranked 159th in the world one year ago, reached the final after eliminating four seeds along the way – Dominic Thiem, Novak Djokovic, Alexander Zverev and Kevin Anderson.
