The Welsh golfer aced the sixth hole during Thursday's opening round. He becomes the fifth golfer to make a 1 at the 180-yard hole known as Juniper. And it's the first since Chris DiMarco in 2004.
Overall, it was the 24th ace in Masters history. Last year, Bo Van Pelt and Adam Scott made holes-in-one at No. 16.
Donaldson's brilliant shot left him at 1 under for the tournament, three strokes behind the leader, David Lynn of England.
