New Zealander Kashif Shuja edged out home favourite Mike Corren in the final of the Chateau Tanunda South Australian Open to win the PSA World Tour Challenger 5 squash event at the South Adelaide Squash Centre in Adelaide.

Corren, the South Australian-born second seed in his fourth final in five years, was looking for his third successive title as he celebrated his 51st appearance in a PSA Tour final - and his fourth this year.

Shuja and Corren entertained the big crowd with some squash of the highest quality before the Kiwi claimed the fifth game in a tiebreak to take the title 11-7, 4-11, 13-15, 11-5, 12-10 after 75 minutes.

"I knew it was going to be very, very hard, even though Mike had a tough semi-final yesterday," said Shuja, the 31-year-old top seed from Auckland.

"He worked so hard today, it was hard physically and I was just pleased to get home - there was nothing between us."

It was Shuja's 10th title on the men's tour, achieving a goal he set himself when he quit his job at the University of Auckland six years ago to go on the tour full time.

"It was very special for me to win my 10th tournament," added Shuja after extending his unbeaten record against the 37-year-old Australian.

"It's also special for me to win here. I've been coming to Australia for many years now and I really appreciate the great squash history in this country."
