Whatley, the PGA Professional at Morley Hayes, Derbyshire, won the event in 2012 after negotiating two rounds of the Northamptonshire course in seven-under-par.
This time, in what was the tournament’s tenth anniversary, he had to hold his nerve in a sudden death play-off to claim the £1,050 winner’s cheque and become the first leader of the region’s Order of Merit.
In doing so he had to repel the challenge of former Ryder Cup star Paul Broadhurst and Jak Hamblett of Handsworth Golf Club.
Hamblett (below) had set the pace in the first round by posting a seven-under-par total of 65 to establish a three-stroke lead over Whatley and the rest of the 78-strong field.
Broadhurst, meanwhile, looked out of contention after reaching the tournament’s halfway stage in two-over. As he did come the turn in the second round despite posting two birdies to go into the back nine on level par.
However, a birdie bonanza as he headed for home saw him finish level with Hamblett, who dropped two strokes in the second round and Whatley, who completed it in one-under.
In total Broadhurst posted six birdies in nine holes and had he not bogeyed the par three 17th there would have been no need for a play-off.
That blip left him needing a birdie at the last to finish level to join the play-off and he obliged courtesy of an approach that was just six foot distant from being immaculate.
Such is golf's ability to bite its participants on their rear ends that, faced with a similar approach shot in the first play-off hole – the par four 18th – Broadhurst dunked his ball into a pond and incurred a penalty stroke that proved terminal.
All of which left Hamblett and Whatley as the last men standing, a scenario that, having negotiated the par four first in regulation, remained until the latter delivered the coup de grace with a birdie at the 18th.
It was the 39th hole Whatley had played and, having been presented with the trophy by Glazerite founder and owner John Hewitt (above), he said: "Today was very much about patience.
"I said to myself at the beginning of the day I was going to miss some putts and I had to stay patient. My big thing was to accept anything that happens and go again on the next hole. That was the case in the play-off. Go again on the next hole and it worked.”
Almost as satisfying for Whatley was repelling the challenge of Broadhurst in the play-off.
"It’s brilliant to be able to say I beat Broady,” he added, "but at the same time I was just concentrating on hitting one shot at a time. Jak had a couple of chances to get in there before me and birdie so you just have to go through your routine and hit the putt.”
While Whatley has become the first player to win the Glazerite Trophy twice, finishing top of the Order of Merit has eluded him. However, he hopes this win will be the launch pad to rectify the omission from his golfing CV.
"I’ve not won the Order of Merit before so I’ve got off on the right foot,” he said. "But it’s the first of four events so we’ll see how things go in the remaining three.”
