Jimmy Walker won this event a year ago by one shot over Chris Kirk. Here are 10 players to watch in Honolulu:

1. Jason Day: The top-ranked player in this week's field, Day enters off a course record-tying 62 in the final round at Kapalua. He hasn't played this event since 2011, when he finished T-20, but Day now has top-five finishes in each of his last three starts in the U.S. dating back to the Tour Championship.

2. Chris Kirk: Like Day, Kirk arrives in Oahu on the heels of a Monday 62 in Maui and has some unfinished business at Waialae, where he finished runner-up a year ago. Kirk also finished T-5 at this event in 2013 and he boasts a 67.3 stroke average in four career trips to Honolulu.

3. Zach Johnson: Johnson appeared in contention to defend his Hyundai title, but despite a disappointing third round he still finished seventh. Now he heads to a course that suits his short-but-accurate style of play, and one where Johnson won in 2009 and finished T-8 last year.

4. Jimmy Walker: The defending champ appeared in line for a win at Kapalua before folding down the stretch. He certainly knows his way around Waialae and now has nine straight rounds there in the 60s, but it remains to be seen how much Monday's playoff loss to Patrick Reed will linger.

5. Russell Henley: Henley set the 72-hole tournament record en route to victory in 2013, and he returns to Oahu after a T-3 finish in Maui where he birdied each of his final five holes. Henley is among the game's best putters, and if he continues to hole putts at the pace he did last week at Kapalua, he'll surely be in contention once again.

6. Matt Kuchar: Kuchar surprisingly struggled over the weekend on the Plantation Course, but his track record at this week's event can't be ignored: T-5, T-5, T-8 in his last three starts dating back to 2011. Kuchar was one of the most consistent players last season, and he'll likely return to that billing sooner rather than later.

7. Hideki Matsuyama: The Japanese phenom held a share of the 54-hole lead last week before ultimately falling one shot short of the playoff, but it was still a strong start and his third top-10 finish on the young season. He hasn't had much success at this week's venue, though, with missed cuts in each of his prior three appearances (2011-13).

8. Tim Clark: Clark withdrew from this event last year because of injury, but his four other appearances all yielded top-25 finishes at Sony, including runner-up showings in 2011 and 2013. Clark isn't long off the tee, but he's certainly accurate with his approaches - he led the Tour last season in proximity to hole. That will come in handy amid the cozy confines of Waialae.

9. Charles Howell III: While he hasn't won, Howell is among the all-time leading money winners at this event after eight top-10 finishes including five in the last six years. Howell has slipped all the way to No. 137 in the world rankings, but Waialae seems to bring out the best in him each year.

10. Marc Leishman: The Aussie is another player with a strong track record at Waialae, having finished no worse than T-27 in five prior appearances. He has cracked the top-10 in each of the past two years, including a fifth-place finish in 2014 after closing with a 65.
