Through his first 25 holes of the 2015 Memorial Tournament, Jason Dufner made four eagles, including back-to-back eagles with a 3 on the par-5 15th, then a hole-in-one on the par-3 16th in Round 2 at Muirfield Village Golf Club.
That puts Dufner within one of the PGA Tour record for most eagles made in a 72-hole event, which is five.
Dufner could also tie the PGA Tour mark of most eagles in a single round with three. Dustin Johnson already made three in a round this year, becoming the first player in Masters history to accomplish the feat by making eagle 3 on the second and 15th holes and a hole-out eagle on the par-4 fifth. The last player to make three eagles in a round and go on to win the event that week was Will MacKenzie at the 2006 Reno-Tahoe Open.
The last player to make a hole-in-one in a tournament and go on to win is Dustin Johnson, who made an ace on No. 8 at TPC Blue Monster en route to winning the WGC-Cadillac Championship.
