Sure, it was nothing on the monetary scale which resulted in the American losing a major after a rules violation, but Bellamy (23) also had his moment of horror which led to a loss, a loss which meant a lot to him in his short career.
Thompson (22) was this week hit with a four-stroke penalty in the ANA Inspiration tournament in California after she was found to have marked her ball and then replaced it in the wrong place on a green.
It was discovered by a television viewer who emailed in the observation to tournament organisers.
Thompson was docked four strokes five holes from home on the final day and eventually lost the tournament in a playoff, making waves right around the world.
Bellamy had his hole of woe in the St Clair championships final late last month.
Lining up in the final against Stephen Hitchcox, the duo played 36 holes to decide the title and, after 35 holes, were all square.
The 18th at St Clair is never the easiest of finishing holes and Hitchcox landed on the apron of the green while Bellamy was in the better position on the green.
But his ball was in line with the line of Hitchcox's ball to the hole. So Bellamy marked his ball, using his putter to get off the line and then waited for Hitchcox to hit his ball.
Hitchcox could not find the hole so Bellamy swiftly stepped up and holed his putt for what he thought was the win.
But, and this is the big but, he had failed to mark the ball back in the original place, not remembering he had moved it to accommodate Hitchcox's line.
So the elation of winning lasted about 10 seconds when an alert member of the public watching the match pointed out Bellamy's mistake.
Bellamy quickly realised what he had done and it quickly sank in - he had lost the hole and with it the chance of going back to back as club champion.
''It was pretty annoying to be honest but the rules are the rules. I just had to hand over the title,'' he said.
''It was just one of those heat-of-the-moment type of things. I don't know what happened. I was just thinking about the putt and did not think about the placement.''
He said he had a pretty good idea who had alerted the officials to his faux pas but it was his mistake first and foremost.
He had the same disappointment as Thompson but the penalty was not as harsh, Bellamy said.
''I missed out on something like $50. She's probably lost hundreds of thousands worth of prize money and the chance of not winning a major. The most disappointing thing for me was not being able to go back to back.''
Hitchcox was a reluctant winner but, under the rules of golf, won the last hole and with it the title.
Bellamy, a scratch golfer, has quickly got over his disappointment, and is now aiming to get into this year's Otago interprovincial team.
He was a reserve for the team last year when it was the bridesmaid at the national tournament in Taranaki.
Bellamy was brought up in Dunedin and still plays pennants golf for the St Clair Blue team.
An aluminum window installer, he works in and around Christchurch for the week but such is his dedication to Otago he comes back every week to play in Dunedin.
