Upsets continued in Kuala Lumpur today where the top two seeds crashed out of the Royal Lake Club Open, the inaugural PSA World Tour Challenger 10 event at the Malaysian capital's The Royal Lake Club.

Kuwaiti favourite Abdullah Al Muzayen looked to be in control in his quarter-final match against Ravi Dixit after taking a two-game lead.

But the Indian qualifier reduced the deficit after a tie-break third game, and was leading in the fourth when a hamstring injury forced Al Muzayen to concede the match.

Dixit's unexpected success now ensures Indian interest in the final as he will meet compatriot Harinder Pal Sandhu (pictured) in the semis. Fourth seed Sandhu snuffed out Sanjay Singh of Malaysia 8-11, 11-8, 11-3, 11-8.

But there will be home interest in the last four after KL-based third seed Kamran Khan defeated English qualifier Nathan Lake 12-10, 11-6, 11-5.

However, in the day's other major shock, Pakistan's unseeded Nasir Iqbal put paid to an all-Malaysian semi after upsetting Muhd Asyraf Azan, the No2 seed from KL, 11-6, 11-7, 11-7.
