El Sherbini Downs Compatriot Adel
World No.1 Nour El Sherbini became the first player to secure a semi-final place at the U.S. Open after she downed compatriot Yathreb Adel in straight-games.
The two Egyptians, who are the same age, had only faced each other once previously on the PSA Tour with El Sherbini winning that one back in 2010.
El Sherbini, who has not dropped a game this week, continued her strong run of form as she put ‘giant killer’ Adel – who knocked out World No.7 Nouran Gohar and World No.15 Salma Hany in previous rounds – to the sword in just 23 minutes.
“I think I played really well,” said World No.1 El Sherbini.
“She has been playing really well all week, she beat Nouran [Gohar] and has been in good form. No-one knows how long we have been playing against each other, we are the same age and have been playing since we were five-years-old. She is really tough to play against and I’m really happy with my performance today.
“The game plan was to be confident and I think I did that today and played my game.”
 Nour El Sherbini (EGY) bt Yathreb Adel (EGY) 3-0: 11-3, 11-3, 11-8 (23m)
Masterclass from Serme Sends Her into Semis
France’s World No.4 Camille Serme put on a masterclass performance to send out home hope Amanda Sobhy and reach the semi-finals in Philadelphia.
Sobhy had enjoyed a huge win over defending champion Nour El Tayeb in round three, however, with the head-to-head heavily weighted in the Frenchwoman’s favour, she put in a flawless display to her reach fourth U.S. Open semi-final.
Serme raced into a 7-0 lead in the first game and from then on just proved too much to handle for World No.18 Sobhy as she claimed an impressive 11-5, 11-8, 11-7 victory in 30 minutes.

She will now take on World No.1 Nour El Sherbini in a repeat of the 2016 final, which Serme won.
“The crowd were cheering a lot for Amanda today,” said the 2016 U.S. Open champion.
“I just tried to stay focused and I’m even surprised with my game today. I hit really good targets and I’m just really happy.
“I knew we had tough matches in the past and I won really close battles, so I knew it was going to be tough and she obviously beat the World No.3 Nour El Tayeb. I just tried to forget about all that and focus on what I needed to do on court and it seemed to work.
“Playing against Nour [El Sherbini] was the final two years ago. I’m just very happy to be back in the semis after losing in the second-round last year. I’m just enjoying my squash and that’s the most important thing.”
 Camille Serme (FRA) bt Amanda Sobhy (USA) 3-0: 11-5, 11-8, 11-7 (30m)
ElShorbagy Prevails in Battle with Abouelghar
Egypt’s World No.1 Mohamed ElShorbagy showed his experience after he knocked out compatriot and World No.9 Mohamed Abouelghar in the quarter-finals.
Abouelghar has enjoyed an impressive start to the season, with the young Egyptian claiming his biggest ever PSA Tour title at the J.P. Morgan China Squash Open. However, the 25-year-old struggled to contain the ‘Beast from Alexandria’ ElShorbagy.

It was a tight opening two games between the two Egyptians as Abouelghar continued to test ElShorbagy. In the third game, however, the reigning World Champion utilised all of his experience to take full advantage of Abouelghar’s errors.
“The way he has been playing, he hasn’t lost a match this season,” said ElShorbagy.
“He’s a great player but I just wanted to go on court with him today and I wanted to show him that how he won the last tournament, he needed to do a 100 times better today. That’s what I always try to do with any opponent I play against, I try to make them feel that they have to do it 100 times better, every time they play against me.
“I have so much respect for him – I know how great a player he is and I knew I couldn’t take him lightly. He has matured this season and I had to treat it like a final today.
“When it comes to those end games you have to be fearless and you have to show your metal and I showed that at the end of the second game when he came back at me. I’m really happy and proud of my performance today.
“Me and David [Palmer] studied that match a lot before today and we had to prepare differently and we got our tactics right but I know he is going to go back and learn from this and come back stronger.”
 Mohamed ElShorbagy (EGY) bt Mohamed Abouelghar (EGY) 3-0: 11-9, 11-9, 11-4 (46m)
Coll Produces on Big Stage to Reach Semis
New Zealand’s World No.8 Paul Coll produced one of the biggest performances of his career after he knocked out World No.4 Tarek Momen in a tight 3-2 battle to become the first male Kiwi to reach the semi-finals of a major PSA event in over 20 years.
Momen took the opening game after he found his accuracy the quickest, however, ‘Superman’ Coll came back in the second to level the scores and turn the contest into a real battle.
The lead continued to exchange hands as both Momen and Coll went toe-to-toe inside Philadelphia’s Drexel University, however, it was the New Zealander – who is renowned as being one of the fittest players on Tour – who prevailed in 96 minutes of attritional squash.
The final game proved to be the toughest on the two players, with both holding matchball at points. However, it was the New Zealander who held his nerve to convert on his second attempt and book a place in the semi-finals of the PSA Platinum event.
He will now take on World No.1 Mohamed ElShorbagy for a place in the final.
“It feels amazing,” said 26-year-old Coll.
“I put a lot of work in over the summer, changing my game and working on a lot of things and it’s feeling really good out there.
“Tarek is a great player and he’s so fast, but I felt that I really found my game more in the fourth and fifth.
“I wasn’t really hitting the ball in the first, I was just patting round and waiting and that’s what I was trying to get out of my game all summer. I focused on that, to hit the ball with more purpose, going into the front and back. Just trying to push up and volley more, I was just trying to get into myself more and push.
“I’ve been working hard on my game, so I’m just excited to see where I am against the best in the world and I’m ready to give it everything I have got and really take it to him and leave it all out there.”
 Paul Coll (NZL) bt  Tarek Momen (EGY) 3-2: 6-11, 11-8, 5-11, 11-7, 13-11 (96m)
