Jason Day has made his 2015 intentions clear with a stunning final round to come within a whisker of a playoff at the Tournament of Champions in Hawaii.

Day, who confessed to making too many simple errors during
the first three rounds, made up for his mistakes with a course record tying
11-under-par 62 in the final round to finish 20-under par for the week and
within one shot of the eventual playoff score.

The Queenslander, one of five Australians in the winner’s
only field at the Plantation Course at Kapalua, expressed frustration after the
second round at his poor play on the course’s par-5 holes.

"It’s so frustrating," Day told AAP after his
second round. "I have scoring clubs in my hands and I’m just not putting
the ball in good positions.

"On top of that, I’m not finishing off the chips if I
am in trouble and it is really annoying because otherwise I am playing really
well.

"At a bare minimum I should be four under on those
holes through two days, especially with my length, but I am just not
capitalising on it."

Despite the frustration the 27-year-old correctly predicted
he would right the ship over the final two rounds.

"If I can put it together the next two days I feel like
I’m certainly still within striking distance," he said.

The prediction proved prophetic. Although a third round 71
was disappointing Day never gave up and came out strong in the final round.

Four straight birdies from the 5th hole had him looking a
slim chance to contend but the fireworks began on the final nine holes where a
7-under-par 30 gave the leaders plenty to think about.

Day’s efforts ensured a thrilling finish to the tournament
where Jimmy Walker and Patrick Reed eventually played off for the title, Reed
victorious on the first extra hole.

Matt Jones, suffering a debilitating virus much of the week,
was the next best Australian finishing 14-under for the week and T11with Steven
Bowditch (T22), John Senden (T25) and Geoff Ogilvy (T27) rounding out the
Australian challenge.
