Cameron Smith believes he will inevitably win The Masters, after his charge for the green jacket unravelled on Sunday.

The Australian went into the final round three strokes behind eventual winner Scottie Scheffler, and he was still in contention with seven holes remaining, before misfortune struck on the 12th hole.

Smith's weekend came undone from there, finishing the round with a one-over 73 and tied for third with Shane Lowry at five-under-par for the tournament.

After winning the Player's Championship in March, the world number six does not view the weekend and eventual faltering of his chances at Augusta National as a learning experience, holding the belief he will eventually put on golf's most coveted prize.

"I don't know really," Smith said. "I feel like I've played some of my best golf around here, it just hasn't quite been my time yet. A couple of lucky breaks here and there, and I'll be putting the green jacket on, I'm sure, one day.

"I feel really comfortable around this place. I feel like it's a place that really suits my game, and I look forward to coming back every year and playing good golf."

After birdieing the 11th hole, the world number six tried to capitalise on momentum and went straight for the pin on the notorious par-three 12th, a hole that leaves little margin of error for the aggressive.

Instead of heading for the safety of the middle of the green, Smith aimed for the narrow strip of green closer to the pin, only for Augusta's Amen Corner to claim another victim.

While his scuffed tee shot and triple bogey on the 12th might take all the headlines, consecutive bogeys after birdieing the opening two holes proved just as consequential, according to Smith.

"Just too many mistakes," he said. "I feel like maybe my two bogeys on the front nine weren't quite deserved – it kind of, I guess, halted my momentum a little bit. I got off to a really good start, birdieing the first two, and then two bogeys to follow that really slowed me down. A poor shot on 12, and there's the tournament.

"It was all fine, it was just a perfect nine iron, it was just a really bad swing. Probably one of the worst swings of the week, and at the worst time of the week. Just unfortunate, but I'll grow from this and be stronger for it."
