Mickelson tops leaderboard
Phil Mickelson shot to the top of the Deutsche Bank Championship leaderboard at the halfway stage of day one following an eight-under-par 63.
The reigning Open champion, fourth in the FedEx Cup standings, was well on course to card a magical 59 after opening his round on the back nine with seven birdies to reach the turn on 28.
While the left-hander, who opened with a round of 60 at the Waste Management Phoenix Open earlier this year, bogeyed the first, he then eagled the next after landing his second shot to two feet from the pin.
However, a run of pars followed before the American finished his round birdie-bogey at TPC in Boston.
It was still enough for a one-shot clubhouse lead over compatriot Kevin Stadler, who made eight birdies and a solitary bogey on the 12th in his round of 64.
World number one Tiger Woods and Barclays winner and Masters champion Adam Scott were in the same playing group as Mickelson although they failed to take inspiration from the 43-year-old.
Woods, who on Thursday told reporters his back problem is not as bad as first feared, struck a 68 although Scott was well off the pace and is currently tied for 86th following a two-over-par round.
Hunter Mahan is currently just behind countrymen Mickelson and Stadler after a six-under-par round, while England's Lee Westwood is in a group of nine players one shot further back.
