Graham DeLaet is in hot pursuit of a maiden title on the illustrious US tour, with the Canadian tied for third at 16 under overall after a blistering nine-under 62 on Sunday. DeLaet is level with American Steve Stricker, who was similarly on fire in his third round as he signed for an eight-under 63. Another local Jason Dufner continued his clockwork-like week in Massachusetts, as he carded his third consecutive five-under 66 to be four shots from leader Garcia.
