Ryan Moore and James Hahn fired six-under-par 65s to grab a one-shot lead after a low-scoring first round at the Deutsche Bank Championship at TPC Boston. Hahn drained an eight-foot birdie putt on his final hole while Moore saved par on his last to inch clear of the chasing pack in the $8.5 million tournament, the second event in the FedExCup playoff series. Brian Stuard, England's Paul Casey, Argentina's Fabian Gomez and Venezuela's Jhonattan Vegas were locked in a four-way tie for third at five under after carding 66s.
