Birdied the final two holes for a 4-under 68 and T2 finish at the Masters Tournament with Adam Scott, two strokes behind champion Charl Schwartzel. The two joined fellow Aussies Bruce Crampton, Jack Newton and Greg Norman who have come painfully close to winning a green jacket. It was quite a week for Day, who equaled the lowest score (64) in any round by a first-year participant (Lloyd Mangrum, first round, 1940, Mike Donald, first round, 1990 and David Toms, fourth round, 1998) with an 8-under 64 in the second round, marking the lowest second-round score by any player in Masters history (Miller Barber, 1979 and Jay Haas, 1995). Fell just one stroke shy of the course record, held by Nick Price and Greg Norman. His T2 comes in just his third start in a major championship: 2011 Masters (T2), 2010 PGA Championship (T10), 2010 British Open (T60).

Survived a ball in water hazard on the final hole to win his first PGA TOUR title at the HP Byron Nelson Championship. At 22 years, 6 months and 11, youngest winner at TPC Las Colinas since Tiger Woods' victory in 1997 at the age of 21. Nearly withdrew Thursday morning because he felt ill due to medication for a lingering sinus infection but finished with a final-round 72 to win at age 22. Held a two-stroke lead over Blake Adams entering the final round. But thought he might have blown it when, holding a one-stroke lead, his approach to the final hole went into the water (for the third time on the week on that hole). But he got a reprieve when playing partner Adams—who said he didn't see where Day's ball went—knocked his ball into the water, too. Day salvaged a bogey to finish at 10-under 270, while Adams took a double bogey and dropped into a tie for second at 8-under with Brian Gay and Jeff Overton.

At the conclusion of the season, he had sinus surgery. 2009: Finished T2 at the Puerto Rico Open, one stroke behind winner Michael Bradley.
