This will mark also Sadom’s debut appearance in a major championship since he turned professional in 2018.
Sadom headed into the final round at the Sentosa Golf Club as co-leaders alongside Sihwan Kim of the United Stastes where the duo enjoyed a three-shot advantage over the chasing packs.
But thanks to Kim bogeying his first two holes of the day, Sadom swiftly secured a two-shot cushion with two pars.
He picked up a pair or birdies on holes sixth and seventh and never looked back since to end the day with a glorious 13-under.
"I’m very excited and happy to have won this tournament.
"There was a lot of pressure on me today, but I did it. A lot of hard work has gone into this victory, and I’m really pleased with myself.
"This is the first time I’ll be playing in a major and I’m really looking forward to be playing against the best players in the world in the home of golf at St Andrews," said Sadom.
