Nick Matthew beaten by Amr Shabana in US Open semi-finals
English world champion Nick Matthew lost 3-1 to Egypt's Amr Shabana in the semi-finals of the US Open.
In a repeat of the 2011 final, which Shabana also won 3-1, the 35-year-old four-time world champion triumphed 11-5 11-9 10-12 11-7 in 63 minutes.
"Got outplayed," wrote second seed Matthew, 34, on Twitter. "The lines he was hitting were too good."
In the women's quarter-finals, Laura Massaro,another English world champion, lost 3-2 to Nour El Sherbini.
Massaro, the second seed, led 2-1 against the Egyptian seventh seed but succumbed to an 11-9 4-11 1-11 11-6 11-5 defeat.
Matthew's defeat, meanwhile, helped bring about a change at the top of the men's world rankings.
Egyptian Mohamed Elshorbagy will become the new number one after he beat the current incumbent Gregory Gaultier 11-4 11-9 11-4 in only 40 minutes.
Matthew said a report he had been punished for "continued verbal dissent" during his defeat by Shabana was incorrect.
The Yorkshireman, who won his third world title in four years in November, wrote: "Just to clarify, I got a conduct stroke for asking calmly for an explanation on a no let. There was zero dissent."
