Woods is off and running this week at the BMW Championship, shooting a six-under 29 during his first round today.
Woods, whose 79 PGA titles are three shy of Sam Snead's record, began on the back nine and opened with a 20-foot birdie putt at the par-4 10th hole, then added back-to-back birdie putts from 13 feet at 12 and 10 feet at the 13th hole.
Woods had ignited thoughts of his career first 59 after an outward nine that produced a seventh hole eagle and four birdies in a six-under par 29.
Woods birdied the first hole to get to seven under through 10 holes, then made five straight pars before feathering a wedge to inside a foot on No. 7.
They led by one stroke from American Xander Schauffele in the third of four playoff events on tour. He hit 16 of 18 greens and was bombing drives, missing just five fairways.
"It felt nice", Woods said of having the Scotty back in the bag.
"I know the release point and I know how it swings and my body morphed into a position where it understands where it needs to be to release the putter".
Not on a course with generous fairways and greens so soft that Woods hit a 3-iron from 242 yards that landed 8 feet in front of the hole and stopped 5 feet away next to the pin.
But 42-year-old Woods bounced back with a birdie at the par-5 ninth to post his lowest opening round at a US Tour event in 19 years.
With temperatures in the upper 90s making Aronimink play short, Woods had an 8-under 62 that included a bogey on his next-to-last hole. "Disappointed I didn't play in the pro-am but also it was the best thing for me".
"Got off to a better start than I have most of the season".
McIlroy pared his 15th but three-putted for bogey both his seventh and eighth holes before a consolation birdie at the last.
His only bogey came at the par-three eighth, where he misjudged his tee shot and sent an eight-iron over the back into punishing rough.
"I made a few putts today, right out of the gate at 10 and 11", Woods said.
Woods will hold a share of the first-round lead for the first time since the 2013 WGC-Cadillac Championship, a tournament he went on to win.
