Gregory Gaultier stunned in New York

Colombian Miguel Angel Rodriguez shocked Gregory Gaultier on Wednesday to reach the last four of the Tournament of Champions in New York.

Rodriguez, unseeded, won a thriller against 2014 runner-up Gaultier of France 11-13 14-12 8-11 11-8 11-9 in 88 minutes.

The second seed had his chances but Rodriguez - who said he adapted his game for the challenge of Gaultier - stormed home on the back of support from the American crowd.

"I'm really happy to be in the semi-finals and I'm going to enjoy it," Rodriguez told the Professional Squash Association's official website afterwards.

"I was ready to play against Greg tonight and the strategy that I prepared with my coach David [Palmer] paid off.

"I knew if I was going to play long rallies against Greg, I wasn't going to win.

"So I tried to volley more I'm very happy with the way I played."

Rodriguez will play third seed Nick Matthew for a berth in the final.

Matthew defeated Germany's Simon Rosner earlier, 10-12 11-4 11-7 11-6.

The Englishman recovered well from a slow start and, despite Rodriguez's breakthrough win, will be a big favourite.

Thursday's other semi-final will see world number one Mohamed Elshorbagy face fellow Egyptian Amr Shabana.

Shabana, seeded fourth, won the event last year.
