Collin Morikawa's caddie aces 'Island Green' at TPC Sawgrass - ESPN

As a caddie, you can be sure JJ Jakovac had a pretty good idea as to the yardage and club to be used while standing on the tee box at the famed par-3 «Island Green» hole at TPC Sawgrass on Wednesday.

It's not often, however, that it's the caddie — and not the professional — making the hole-in-one in front of a raucous crowd.

But Jakovac, who is the caddie for world No. 4 Collin Morikawa, did just that. Using a pitching wedge from 131 yards, his ball landed on the downslope of the green and rolled back into the hole for a memorable ace.

«It had to ride the wind to get there,» Jakovac said, according to Golfweek. Right as it came off, I was like, that's a perfect line if it lands the right distance. It started spinning, and I was like, 'This has a heckuva chance.'"
