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 Friday. 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. Australia's Adam Scott — winner of the inaugural Deutsche Bank crown in 2003 — was amongst a bunch of 13 players tied for seventh, two strokes off the pace. Moore and Hahn opened up their slender advantage after recording bogey-free rounds with six birdies apiece on the demanding 7,207-yard layout. World No. 43 Moore is chasing his sixth PGA Tour title, just a month after winning the John Deere Classic by two shots. The 33-year-old is 11th in the lucrative FedExCup standings could climb to second overall with a victory this weekend. Hahn enjoyed a near flawless round, hitting every fairway in regulation for the first time in his professional career. The 34-year-old Korean-born world No. 65 is seeking the third win of his PGA Tour career, with the most recent victory coming at the Wells Fargo Championship in May. Casey and Gomez had set the early pace in the morning flights, although Stuard briefly went to six under before faltering with back-to-back bogeys before finishing with a birdie. World No. 2 Dustin Johnson, No. 3 Jordan Spieth, Sweden's No. 4 Henrik Stenson, Patrick Reed and Olympic champion Justin Rose of England are all three shots adrift. Reed is well-positioned for a charge over the weekend as he looks to build on last week's victory at The Barclays. Defending Deutsche Bank champion and world No. 8 Rickie Fowler is four off the lead, tied for 38th, after carding four birdies and a pair of bogeys. World No. 1 Jason Day of Australia is also in touch at one under after an eventful day which saw his wife Ellie and children escape injury in a traffic accident. Ellie Day was taken to hospital as a precaution but later released. "Thankfully everyone is now resting comfortably," said Day, who is tied for 48th with Fiji's Vijay Singh and 2014 Deutsche Bank winner Chris Kirk among others. Northern Ireland's world No. 5 Rory McIlroy and Bubba Watson are tied for 67th six shots back. But it was a miserable day for Phil Mickelson, who ended up carding a quadruple bogey at the 439-yard par four sixth hole. Mickelson finally finished 10 strokes off the lead, tied for 93rd.
