Only the leading 70 players at the completion of this week will advance to the BMW Championship at Cherry Hills in Colorado so in addition to the significant purse this week one of the last chances for several still with Ryder Cup hopes there is also a battle for survival.
Henrik Stenson will look to defend the title he won in the middle of a stunning run of form last year which swept him to the FedEx Cup Championship. He won by two shots over Steve Stricker.
Stenson may not be at quite the same level this year but his 3rd place finish at the PGA Championship suggest he is not far short of it and if he was to successfully defend there would be no surprise.
Other recent winners include Rory McIlroy, Webb Simpson, Charley Hoffman and Steve Stricker.
The TPC Boston layout was an original Arnold Palmer designed layout although reworked in 2007 by Gil Hanse who has also been given the responsibility of creating the layout for the 2016 Olympics.
After three consecutive victories Rory McIlroy was below his best last week in New Jersey but as a previous winner and with so much residual form at present he is the man to beat. Even when he has not won this event McIlroy has found a way to produce a good round at the TPC Boston and clearly has a liking for the layout.
Adam Scott won this event back in 2003 and then finished runner-up the following year and although his results have been mixed since then he has also recorded three other top tens so he too has a liking for the TPC Boston. Scott seems to contend or be on the edge of contention in everything he plays now and this week should provide no exception.
Jason Day again displayed last week that despite his struggles with injury this year he can contend at the highest level. Day finished runner-up in 2010, 3rd in 2011 and 13th last year. His great runner-up finish last week gives an indication he is ready to win his t4th PGA Tour title to go with his Byron Nelson, World Cup and Accenture titles.
Despite not winning this event, Jim Furyk has done well enough to be a consideration especially given his great form this season. Three runner-up finishes this season and plenty of other top tens tell the story of a man playing close to his best.
With Ryder Cup selection perhaps hinging on results this week there is perhaps no better time for Brandt Snedeker to stake a claim. Despite being currently 20th in the points standing Snedeker is no doubt still in Tom Watson's mind for one of this three wild card spots and a big week this week might help sway his decision making process.
Although missing the cut last week, Snedeker has generally played solidly in recent events. He does have some good form in this event and certainly has the motivation.
Matt Kuchar finished 4th last year and continues to play well nearly every week he tees it up. He was 5th last week, 12th in Ohio and 4th at the Canadian Open.
Webb Simpson is in a very similar situation to Snedeker and although a little inconsistent of late, missing good form with bad, that he has won here improves his chances.
The Australian chances appear likely to rest with Scott and Day although Geoff Ogilvy has shown some improvement of late and did finish runner-up here a few years ago.
Others in the field are Marc Leishman, Matt Jones, Steve Bowditch, John Sendenand Stuart Appleby who will be joined by New Zealander Danny Lee.
