Marc Leishman maintained his lead Friday over a star-studded field at the 2017 BMW Championship, carding a 7-under 64 to take a three-shot lead into the weekend at Conway Farms Golf Club in Lake Forest, Illinois.

The 33-year-old Aussie followed up a 10-birdie performance on Thursday with eight more on Friday to remain atop a leaderboard that also includes 2015 BMW Championship winner Jason Day and American star Rickie Fowler.

“Hopefully I can keep this going, birdieing half the holes,” Leishman said. “I’m happy with the first two days, obviously. I made lots of birdies, and the game feels in a really good spot in all aspects.”

Leishman’s best finish at the BMW Championship came in 2009 at Cog Hill when he finished tied for second, eight shots behind eventual winner Tiger Woods.

He will be paired in the final group Saturday with fellow Aussie Jason Day, who shot 6-under 65 – a round that included a hole-in-one on the 188-yard par 3 17th.

Day’s ace, his second career hole-in-one, not only helped him stay within shouting distance of the red-hot Leishman, it also resulted in a $100,000 donation from BMW to the Evans Scholars Foundation, the event’s sole charity.

Day said he’s confident with the state of his game going into the weekend.

“I’m driving a lot better this week, and the iron shots are a lot cleaner,” Day said. “My putting is coming around too, which is nice. I’ve got to focus on trying to see if I can do that over the next few days as well.

The third round begins tomorrow at 7 a.m.
