Simon Rösner became Germany's first-ever Professional Squash Association (PSA) World Series finalist by defeating France's Grégory Gaultier at the Tournament of Champions in New York City.

Number one seed Gaultier had looked to be in control from the start of the semi-final against an opponent he had beaten in 16 out of their last 17 meetings, as he went 11-9 up in the first game at Grand Central Terminal.

Rösner, however, recovered brilliantly to take the next two games 12-10, 11-8 before thrashing his opponent 11-1 in the fourth and final game to complete a 3-1 win.

After his win, Rösner said: "It's definitely the biggest win of my career.

"To beat him at this stage and reach the final is amazing.

"I think I've lost to Greg more than 16 times, I think I've lost to him about 30 times including the Europeans and World [Team] Championships.

"I know I've beaten him before, but that was a best-of-three format [during the 2013 PSA World Series Finals] so beating him in a best-of-five is unbelievable.

"I don't know how to describe it, it's the best feeling in the world."

The world number eight will face Egypt's Tarek Momen in the final after he came through a five-game thriller against compatriot Ali Farag.

The gruelling 80-minute affair ended in a 3-2 win for number seven seed Momen after he came through 11-3, 2-11, 14-12, 6-11, 11-9.

Momen and Rösner's appearances in the final means there will be a new name etched onto the trophy tomorrow (January 26).

The strength in depth in Egyptian squash at the moment is demonstrated by the women's draw with Nour El Sherbini and Nour El Tayeb set to contest the final.

World number one and recent PSA Saudi Masters title winner El Sherbini recovered from a game down against England's Laura Massaro to eventually win 3-1.

Massaro, however, will feel disappointed she squandered a game ball in the second game, giving the momentum to her Egyptian opponent.

Following her win, 2016 Tournament of Champions winner El Sherbini said: "At the beginning, she was killing everything.

"Even though I was sure I was going to lose the first game, I just wanted to get some points and play until the last point.

"I think the second game was very crucial and I think that's what made the difference."

The other semi-final saw number eight seed El Tayeb get past world number three Camille Serme of France by a 3-0 scoreline in just 36 minutes.

Both finals will take place tomorrow.
