Jason Day hit a stunning hole-in-one at the BMW Championship on Friday to stay in touch with runaway leader and compatriot Marc Leishman.
Leishman started the day two shots ahead of Day and shot a superb seven-under-par round of 64 to follow up his opening 62 and finish 16-under at the halfway stage, three ahead of Day and Rickie Fowler (64).
Australian Leishman carded eight birdies and a bogey as he tore up the Conway Farms course in Chicago for a second successive day.
World number nine Day had earlier aced the par-3 17th, the spectacular tee shot came just minutes after a chip-in eagle at the par-5 14th.
“My last hole-in-one was at Turning Stone in 2008, so I’ve had a bit of a dry spell,” Day said after his round.
The generous Day then donated the BMW M760i he won for the ace to the Evans Scholar foundation which provides college scholarships to caddies..
Day’s spectacular finish helped him to bounce back from a poor start that saw him hit two bogeys in his first four holes.
America’s Patrick Cantlay is in fourth position at 10-under par after a 65, while Francesco Molinari (65) of Italy lies a shot further back at nine-under.
