Rule the Day: Jason Day Records 10 Birdies and Leads Deutsche Bank With Johnson

"Taking the putter back more square made a difference I guess," said Aussie Jason Day who couldn't help but blush and smirk at his tournament leading eight-under(-par) 63 at the Deutsche Bank Championship, which got underway Friday morning at TPC Boston.

Day was the story early at the second event of the Fed-Ex Cup Playoffs. The 23-year-old Aussie played nearly flawless golf, hitting 85% of the fairways, 77% of greens in regulation, and needing just 23-putts  for 10 birdies. But Day was not the only player who took advantage of the soft, vulnerable, "lift-clean and place" conditions of the golf course.

Despite the gloomy weather, Zach Johnson shined, sinking almost every putt he faced inside 15-feet and is currently tied for the lead with Day at eight-under. Johnson ranks 10th in Driving Accuracy and sixth in Putting Average on Tour and played without a blemish on his scorecard, making ten pars and eight birdies look like child's play.

The Day One scores of the Deutsche Bank Championship are unbelievably low, with already 40+ players at four-under(-par) or better.

From Geoff Ogilvy (-7), who had two separate stretches of three birdies in a row, to Hunter Mahan (-7), a two-time winner this season, to Rory McIlroy (-6), the ruthless 21-year-old sensation, this field of dogged competitors are putting on a clinic.

After suffering the disqualification for oversleeping his tee-time at last Wednesday's Barclay's Pro-Am, not only did Jim Furyk wake up for his early morning tee time, but he claimed his revenge blistering through TPC with a five-under(-par) 66. Furyk hit every fairway, 94% of the greens in regulation and is currently eighth in Fed-Ex Cup points, meaning he can be in the running to win it all if he can capitalize this week at the Deutsche Bank.

It was a pleasant sign of progress to see Anthony Kim card four-under(-par) 67 in his opening round. This was definitely Kim's best round of golf since returning at Firestone, which hopefully quelled some fears of Ryder Cup Captain Corey Pavin, who must be watching anxiously to see if Kim has healed from his injury.

Don't be surprised if players like Retief Goosen (-three), Ricky Barnes (-3), Rickie Fowler (-4), and Bubba Watson (-4) turn in low scores in Saturday's second round and climb the leaderboard.
