Austrian Sepp Straka soared to the top of the leaderboard at the Hero World Challenge in the Bahamas on Saturday, firing two eagles and four birdies in an eight-under-par 64 to take a one-shot lead over two-time defending champion Scottie Scheffler.

Straka’s round at Albany Golf Club in Nassau was the day’s best, giving him a 54-hole total of 17-under 199 heading into Sunday’s final round of the unofficial 20-man tournament hosted by Tiger Woods.

World number one Scheffler held the solo lead through 15 holes but stumbled with two bogeys in the final three, carding a 65 for a total of 200.

“I played pretty nicely,” Straka said. “On the front nine, I didn’t make many putts early on, but the putter felt good around the turn. My iron play was really solid, though I struggled a bit with the driver.”

Straka, a two-time PGA Tour winner this year and a member of Europe’s Ryder Cup-winning team in September, had withdrawn from two European Tour playoff events to spend time at home in Georgia with his wife Paige when their premature two-month-old son was discharged from the hospital in August.

Both Straka and Scheffler began the day one stroke behind a group of five tied at 10-under. Straka birdied the par-five third, chipped in for eagle at the sixth, and added birdies at the seventh, ninth, and 11th holes, including a 19-foot putt. He capped his charge with a 17-foot eagle at the 15th.
