The hunt for golf's biggest reward —
A cool $10 million is on offer for the winner of the PGA Tour's FedEx Cup this week, with only the top five golfers in the playoffs' rankings in control of their own destiny.

1. Chris Kirk —
Chris Kirk leads the pack, having won the Deutsche Bank Championship, the second of the four playoff events. The 29-year-old also claimed January's McGladrey Classic and was runner-up at the Sony Open later that month.

2. Billy Horschel —
Billy Horschel follows in second place, and goes into the Tour Championship finale in hot form after triumphing at last week's BMW Championship last week -- the second title of his PGA Tour career. The 27-year-old American was joint-second the week before at the Deutsche Bank Championship.

3. Bubba Watson —
Third-placed Bubba Watson, who claimed his second U.S. Masters title in three years back in April, is back in form after a recent slump -- the American was second behind Horschel at Cherry Hills.

4. Rory McIlroy —
Fourth-placed Rory McIlroy has had a summer to remember, with the world No. 1 winning major titles at the British Open and U.S. PGA Championship, as well as triumphing at the WGC-Bridgestone Invitational, in the space of a month. His best finish in the three playoff events so far is a tie for fifth place two weeks ago.

5. Hunter Mahan —
The last of the quintet is Hunter Mahan, who claimed the first of the FedEx playoff titles last month with his victory at The Barclays. Along with a seventh placing at the PGA Championship, it earned him a captain's wild-card pick for the U.S. Ryder Cup team.
