The 24-year-old Jazz, who sealed the 2019 Asian Tour Order of Merit crown last week, signed for a closing seven-under-par 65 and a four-day total of 23-under-par 265 to win by five shots over countryman Gunn Charoenkul at the Royale Jakarta Golf Club.

With a total of 20 Official World Golf Ranking (OWGR) points on offer at the Indonesian Masters, which is the flagship event of the Asian Tour, Jazz is set to break into the world’s top-50 ranked players following his victory and secure a coveted berth at the Masters next April.

“It’s been a very fulfilling year so I am excited about what lies ahead in 2020. A lot of people say I'm going to be a busy man next year but I think this is good to be busy in golf, so I'm looking forward to it,” Janewattananond said.

Starting the day with a one-shot lead, Jazz reeled in five straight pars before sinking three birdies to turn in 33. He would pull four shots clear after striking a brilliant approach shot to three feet en route to a second straight eagle on the 574-yard par-5 12th hole.

Jazz would seal the deal with three birdies against one bogey in his closing five holes to become the second Thai following Poom Saksansin to triumph in the US$750,000 event, which forms the third leg of the 2019/20 Panasonic Swing.

At the age of 24, Jazz is also the youngest player to achieve five victories on the Asian Tour. He will be the third Thai, following Thongchai Jaidee in 2009 and Kiradech Aphibarnrat in 2015, to break into the world’s top-50.

Jazz will take home a winner’s prize purse of US$135,000 and bring his season’s haul to US$968,524 and break the US$2million mark in his career earnings on the Asian Tour, where he started playing as a full member in 2012.

He has also secured a coveted berth at the World Golf Championships – FedEx St. Jude Invitational in 2020, thanks to his victory at the Indonesian showpiece, which celebrated its ninth consecutive edition on the Asian Tour this week.

Gunn posted a 69 to finish second while Korea’s Taewoo Kim and Australian Josh Younger carded respective rounds of 65 and 66 to share third place on 271. Kim and Younger would break into the top-60 on the Merit rankings, giving themselves a chance to secure their cards for the 2020 season.

Danny Masrin wrote a slice of history by becoming the best local finisher in the tournament. He ended his campaign in style with an eagle on the 18 to sign for a 66 and grab a share of fifth place on 273. The record was previously held by Rory Hie when he finished tied-ninth in 2011.
