Goosen and Ishikawa in front

Japan’s Ryo Ishikawa and Retief Goosen of South Africa carded eight-under-par 63’s to take a one-shot lead following the first round of the Quicken Loans National.

Justin Leonard, Kevin Chappell and Ernie Els trail the leaders by one stroke after firing seven-under-par rounds of 64.

Former world number one Tiger Woods is in a tie for 27th, five shots off the pace after a first round of 68.

Ishikawa started his bogey free 63 at the tenth tee, and after a string of pars made five consecutive birdies from the 14th to 18th hole before picking up a further shot at the first.

The six birdies proved to be just a build-up to a sensational finale as the 23-year-old recorded an unbelievable hole-in-one at the 178-yard par-three fourth hole. It was Ishikawa’s second career hole-in-one, with his first ace coming at the 2013 Puerto Rico Open.

Ishikawa was not the only player to register an ace on the day, as Rickie Fowler, who carded a four under par 67, closed out his round in grand style when he registered an incredible hole-in-one at the 176-yard ninth. It was also the second ace of Fowler’s career, with his first coming at the 2009 Open.

“Made a great swing,” said Fowler on

“Spun to the right…I was trying to cut it. Rolled in with perfect speed.”

Meanwhile, Ishikawa was impressed with his work on the greens ion Virginia.

“It was a great day for my putting,” he said.

“I just putted them perfectly. I just didn’t miss a putt.”

Goosen too enjoyed a bogey free round, making four birdies on both the front and back nine. The South African stayed consistent throughout the day, with one of the highlights of his round an impressive 30 foot birdie putt at the par five eighth.

Leonard, Chappell and Els all had solid rounds at Robert Trent Jones Golf Club on Thursday to sit within striking distance of the leaders.

Chappell produced a bogey free, registering seven birdies, including three in a row from the 12th to 14th hole. Leonard notched up eight birdies, including three on the bounce from the fourth to sixth hole, and a lone bogey, while Els recorded six birdies, a bogey and an eagle at the par five 14th.

Steve Wheatcroft, Jeff Overton, Mark Hubbard and Andy Sullivan all sit two strokes behind Ishikawa and Goosen in a tie for sixth after firing six-under par 65s.

Meanwhile, Woods had a strong showing on Thursday after missing the cut at the Open Championship after rounds of 76 and 75.

The former world number one carded a three under par 68, which consisted of six birdies, including four in a row from the 10th to 13th hole, and three bogeys. As a result, he currently sits in a tie for 27th, five strokes off the lead.
