NORTON, Mass. — Vijay Singh made three long birdie putts today and closed with an 8-under 63 at the Deutsche Bank Championship for his second straight victory to build a huge lead in the FedEx Cup playoffs.

Singh, who won The Barclays last week in a three-man playoff, was one shot behind Mike Weir going to the back nine of the TPC Boston when he started making just about everything from everywhere. He made consecutive putts of 35 feet and 60 feet to build a three-shot lead, then rolled in another putt from 35 feet on the 17th.

That gave him his third victory in the past five weeks, and turned the FedEx Cup into a snoozer. Singh has such a large lead that he could clinch the $10 million prize without even playing the season-ending Tour Championship.

Weir fell to 1-9 when he has had at least a share of the 54-hole lead.

Singh finished at 22-under 262 to break the tournament record by two shots in the six years of this event. And the $1.26 million for winning put him atop the PGA Tour money list over Tiger Woods, who has not played since June.
