Singh has one eye on Boston challengers

NORTON, Massachusetts: FedExCup points leader Vijay Singh will be keeping one eye on his closest rivals when he bids for a third PGA Tour title in five starts at this week's Deutsche Bank Championship outside Boston.

Fresh from victory at the Barclays Classic on Sunday, Fijian Singh is in pole position with three playoff events remaining but accepts much can change before the series ends.

"I'm just going to go out there and play hard for the next few weeks," Singh told reporters after beating Spaniard Sergio Garcia and American Kevin Sutherland in a playoff for the Barclays title.
