After defeating his elder brother Mohamed, the world number one, in the quarter-finals yesterday, Elshorbagy regrouped and came through a last four encounter with his compatriot Ali Farag 11-8, 11-9, 8-11, 11-9 at the University Club of Chicago.

He will now take on Frenchman Gregory Gaultier, the world number three, in tomorrow's final.

"It was very hard to back up what happened yesterday - emotionally, mentally and physically," said Elshorbagy.

"I didn't sleep very well last night and I tried to stay away from my phone - there was a lot of messages on social media.

"But my brother called me before the match today and helped prepare me for it - he gave me the game plan and told me that these opportunities, once you get them you have to take them.

"I've had some good wins so far to reach the final but I want to keep it going.

"I really want that title and I'll give it everything that I have tomorrow."

Gaultier, the winner of this tournament in 2014, secured his place in the final by defeating unseeded Spaniard Borja Golan in straight games.

Golan scored an impressive victory over Egypt's reigning world champion Karim Abdel Gawad yesterday and frustrated Gaultier in the opening stages.

But the former world number one found a way through, saving four game balls in a mammoth 28 minute second game on the way to a 11-6, 15-13, 11-8 win.

"It was a really intense match - we were both playing well," said Gaultier.

"It's great to see Borja back in good shape after his injuries and the second game was unbelievable.

"It could have gone either way but I took the momentum with me into the third.

"I'm feeling like I'm in great shape and I'm looking forward to tomorrow."

In the women's competition, Egypt's Raneem El Welily won a lengthy battle with her compatriot, 19-year-old Nouran Gohar.

El Welily was forced to come from behind twice to take the match 7-11, 11-6, 9-11, 11-5, 11-9 in 62 minutes.

"Today at the end, there was so much relief - it was so intense," said El Welily.

"She played fantastic.

"I'm just very happy to be through.

"It's amazing to be in the final for a fourth time - there's no pressure tomorrow but it would be fantastic to win here for the third time."

El Welily will now face another Egyptian, world number one Nour El Sherbini, in a repeat of last year's final.

The 21-year-old signalled a return to top form with an impressive 3-1 win over Camille Serme, ending the Frenchwoman's 12 match winning streak in the process.

El Sherbini lost the opening game 8-11 but rallied to take the next through 11-3, 11-6, 11-4 to secure her place in the final.

"It feels like things are coming together this week - I regrouped and trained very hard the past few weeks," said El Sherbini.

"I feel like I'm playing well again and I'm trying to enjoy being out there. 

"I'm happy more with the fact I'm playing well than with the win.

"There are no expectations for me tomorrow - I'll do my best to win."
