After facing a four-shot deficit to begin the third round, Tiger Woods moved to the top of the leaderboard on the heels of a 6-under 66 Saturday. Here's the skinny heading into the final round, where Woods holds a two-shot lead over three players as he looks for his eighth career API title:
What it means: Rose distanced himself from the pack early, beginning his round 4 under through four holes, but his back-nine stumbles combined with Woods' rally gave the lead to the defending champion. Woods now holds a 54-hole lead, a position he rarely relinquishes, on a course where he has dominated in the past.
Round of the day: Olesen began his round on fire Saturday, carding birdies on each of the first four holes and five out of the first six. The young Dane dropped his only shot of the day at 15, but more than made up for it with birdies at both 16 and 18, as the 23-year-old was one of four players to card a 6-under 66 in the third round.
Best of the rest: Beginning the day eight shots off the pace, Keegan Bradley played his way back into contention by matching Woods, Olesen and Matt Every for round-of-the-day honors. Bradley made eight birdies on the day, more than any other player, including five on the back nine en route to a 6-under 66. Despite opening with a 2-over 74 Thursday, the former PGA champion will now begin the final round tied for 10th, four shots behind Woods.
Biggest disappointment: After beginning his round with two straight birdies, Haas appeared ready to go toe-to-toe with co-leader Rose. When a double bogey on the fifth was followed by another on the par-4 10th, though, Haas fell back to the pack and was ultimately the only player among the top 19 to shoot over par Saturday, carding a 1-over 73 to drop back into a tie for fifth at 8 under.
Main storyline heading into Sunday: Are we 24 hours away from a new world No. 1? With a win, Woods will supplant Rory McIlroy atop the world rankings, a position he last held in October 2010. It would be his third win of the young 2013 season, giving the 14-time major champ even more momentum heading into the season's first major.
Shot of the day: Playing alongside Woods, Fernandez-Castano went just over the green with his second shot at the par-5 sixth. Facing a downhill shot with water looming just past the pin, the Spaniard hit a deft chip that rolled gently into the hole for an eagle 3, helping him to a 4-under 68 Saturday.
Quote of the day: 'Generally our schedules are such that once we figure out what golf courses we like, we tend to play them ... there have been a few events over the course of my career where I've played well, and this is one of them.' – Woods
