NORTON: Ryan Palmer rolled in nine birdies en route to a 63 to grab a one-shot lead after the first round of the Deutsche Bank Championship, the second leg of the FedEx Cup playoffs. The 37-year-old American is aiming for his fourth career US PGA Tour win. He finished runner-up earlier this year at the Honda Classic and the Humana Challenge. Palmer’s American compatriot Keegan Bradley is in sole possession of second after firing a bogey-free 65 at the TPC Boston. Australia’s Jason Day, runner-up four years ago, has a share of third at five-under.
