Rising star Tom Kim says he's just getting started after matching Tiger Woods PGA Tour record

Kim became the first player since Tiger Woods to claim two wins on the US-based circuit before his 21st birthday by winning the Shriners Children's Open in Las Vegas on Sunday.

The 20-year-old from South Korea posted a tournament record-equalling total of 24 under par and was the first player to manage a bogey-free 72 holes on the PGA Tour for three years.

Kim had no status on the PGA Tour when he finished third in the co-sanctioned Scottish Open in July, but won the Wyndham Championship a month later and was hailed a potential "global superstar" by captain Trevor Immelman following his performance in the Presidents Cup.

Speaking about his success ahead of the ZOZO Championship at Narashino Country Club, Kim told a pre-tournament press conference: "It's crazy.

"The second one (victory) is a little bit more special because you have a lot of people where you can do it once, but can you do it twice? I feel like doing it twice has definitely a big meaning to it.

"But beating Tiger is, I mean, it's amazing for me. I've just got to keep playing well and hopefully I'll have a lot more in the bag.

"I haven't achieved the goals that I've wanted yet. The two wins and playing on the PGA Tour is just one of those steps. There's always alternate goals that you want to achieve and I'm just working towards that and these are just stepping stones.

"I'm grateful for what I have now, but I still have a lot what I want to do and I want to accomplish."

Asked to explain his rapid rise on the PGA Tour, Kim added: "I think it's (because) I had the opportunity to go out there a lot before I made it out on Tour.

"Qualifying for major championships and having a few exemptions here and there, I had some time to adjust a little bit. I had no idea if I was going to win or not, but I've just been very fortunate to do so."
