You might not have paid attention to the first three rounds, but we've got a quick recap and prep for what you need to know going into the final round of the Humana Challenge.

TV: Golf Channel at 2 p.m. ET

Leader: Scott Stallings (-22)

1st prize: $1 million

Round of the tournament: Brian Stuard (62) -- he needed to go birdie-birdie on the last two holes Saturday for a 59 but went par-bogey.

Favorite: Stallings is a 4-7 favorite with his five-shot lead. Given his 66-65-62 start it's pretty hard to see him blowing it.

Darkhorse: James Hahn is 125-1 and currently eight back of the lead. We know he can go low, though (63 on Thursday), so keep an eye on him if he gets off to a hot start.

Three storylines

1. Stallings is trying to join the "best young American golfer" conversation -- a convincing win Sunday would get him within striking distance.

2. Is this the year Charles Howell III breaks through with a monster season? He's arguably been the most consistent golfer over the first few weeks of the PGA Tour season, and a top-five finish (he was five back overnight) would only solidify that notion.

3. Russell Henley is trying to back up his win at the Sony Open with a top-10 finish in the desert. He started the day 10 shots back but only four back of the top 10. A big day for him would definitely catch some attention.
