Japan's Ryo Ishikawa fired a hole-in-one during a sparkling eight-under-par 63 to grab a share of the lead Thursday at the US PGA Quicken Loans National.
The 23-year-old Asian star also reeled off six birdies in a row to match two-time US Open champion Retief Goosen, a South African twice Ishikawa's age, atop the leaderboard with much of the field still on the course at the 7,385-yard Robert Trent Jones Golf Club.
