The dashing Indian ended a 12-year barren run when he claimed his maiden Asian Tour victory by producing a grandstand finish with a 12-foot birdie putt on the last hole to pip Bangladesh's Siddikur and compatriot, Gaganjeet Bhullar to the title by two shots.
Memories of his career breakthrough are still etched firmly in Singh's mind and he is hoping he can revive them as he chases his second Asian Tour win at the Delhi Golf Club.
"It'll be my first time defending a big tournament, so I'm taking positives from last year and we shall see what happens. I just hope to go out there and enjoy myself."
Singh insists age is not a factor when chasing for glory on the golf course.
"In this game, age is not a factor. Peter Senior won (the Australian Open) at 53, Tom Watson almost won (the British Open) at 59. Age is not a barrier, it's how you conduct yourself over four rounds of golf," said the 41-year-old.
