After scripting several successes as a junior, this was Kush Kumar's first title as a senior pro in a PSA world tour event.
Kush, who has been with the Indian Squash Academy in Chennai since the age of 14, has had a dream run in the tournament. He defeated Rohan Toole of Australia in the first round 11-4, 11-13, 11-2, 11-0, then edged out eighth seeded Thomas Calver (Aus) 11-3, 11-6, 11-7 for a semi-final entry.
