Tiger Woods came into last year's Bridgestone Invitational on a roll. He'd won three out of five PGA Tour events, and went on to win at Firestone for the fourth straight time.
This year, Woods enters the tournament riding a five-tournament winless streak.
Will he be able to snap out of it this week in the final WGC event of the year?
And what about the added element of "bubble" players, who need to cash a decent check to put themselves in a position to play in the PGA Tour's FedEx Playoffs, which start in only four weeks?
Our experts make their predictions.
Stewart Cink lost in a playoff to Tiger Woods last year and won the tournament in 2004.
Tiger Woods' record at this event: Win, Win, T-2, T-4, 4, Win, Win, Win. Guess that's what happens when you get free drops from the clubhouse roof.

Get a look at Tiger Woods' record at Firestone. Since 1997 he has won there five times and has been second once, fourth twice and fifth once. Enough said.

No one averages more birdies than a guy whose name says it all -- Jonathan Byrd. He should continue building on his win at the John Deere.

Andres Romero was third at the British Open and then won his first event on the European Tour in Germany. This will be his first World Golf Championship event.

Did I mention Tiger Woods is a lock for his first fatherhood victory?
Phil Mickelson's season has been one of ups and downs. He won at Pebble then struggled for a while. He won the Players then missed the cut at the U.S. Open.
