It has been another pulsating PGA Tour season, but as with everything in life all good things must come to an end. And the best way to cap a campaign that has more ups and downs than your average soap opera is with the FedEx Cup.

This tournament essentially confirms who has been the most consistent player on Tour all season, although with the vast amount of points available in the final four events of the campaign there is still plenty of time for an outsider to work their way into contention. The top prize is $10 million, so there is certainly a lot to play for!

How the FedEx Cup Works

Initially, players earn FedEx Cup points throughout the season, and these are carried forward to determine the top 125 players in the world, who now go on to do battle in these play offs.

There are four more tournaments to play, and with big points tallies on offer the rankings of this 125 can change markedly. The four remaining events are The Barclays, the Deutsche Bank Championship, the BMW Championship and the Tour Championship.

After the BMW Championship, the field of 125 will have been whittled down to just 30 – and the points reset relative to the tallies of that top 30. This ensures that any of these players have a shot at lifting the trophy, but ultimately favours the top 5 or so.

This system can create ‘outsider’ winners. Last year Billy Horschel entered into a hot streak at the start of the final four tournaments and surged up the rankings from a starting position of 69th. However, and punters should be aware of this, five of the last eight winners were ranked in the top ten prior to the start of the final four events.

The Contenders

Two-time major winner and golfing wonderkid Jordan Spieth heads the way in the current rankings after a phenomenal season, and he is being chased by Jason Day, whose fine recent showings – as predicted in the betting odds at the 2015 PGA Golf Championship – have catapulted him up to number two. The left-handed Bubba Watson makes up the top three.

Tiger Woods, Jim Furyk and Brandt Snedeker are the most decorated players in FedEx Cup history, and whilst Woods misses out this year after only being able to finish in 10th at the last qualifying event, the Wyndham Championship, both Snedeker and Furyk are very much in the mix.

It will be well worth keeping an eye on the standings from these last four events to see if Spieth romps away to win the title, if Day or Watson can chase him down, or a complete outsider shoots through the pack to complete a surprise victory.
