Cameron Smith feels he could win a couple of Masters titles if he replicates his history-making Augusta performance.

Smith became the first player in Masters history to card all four rounds in the 60s at the major tournament after going 67-68-69-69, but he still finished runner-up on Sunday.

The unheralded Australian ended the rescheduled event 15 under, level with Sung-jae Im, but still five strokes adrift of record-breaking champion Dustin Johnson in Georgia.

It was Smith's best major performance, having tied for fourth at the 2015 U.S. Open.

After achieving a first in The Masters' 84 years, Smith told reporters: "I had no idea starting today that I needed to do that. That's really cool. 

"I honestly can't believe it, but just got to put it down ‑‑ myself, just got to put it down to just scrambling and digging deep. There were a few times throughout week where I could have let it slip away, and it didn't."

Reflecting on his bittersweet display, Smith – winner of two PGA Tour titles and as many on the European Tour – added: "It would have been cool to do that and win. I was actually saying before, you know, I'd take 15‑under around here the rest of my career and I might win a couple. 

"It's just the way it is. I felt as though I didn't quite have my longest stuff, like I said, this week, but my scrambling was what kept me in it."

"I felt like I got away with a lot this week, a bit of skewwhiff shots into the green, something I might need to tidy up if we're coming back here and it's firm and fast," continued the 27-year-old, who was tied for fifth at the 2018 Masters.

"But I love the place. I want to win here really badly, and I feel like it brings the best out of my game."
