But Perez and his caddie executed a near-perfect chest bump after his ace on Friday. Almost like they've practiced their celebrations as much as their shots. Well have to deduct a few points from Perez on the landing, but credit to him for keeping his a balance and staying upright.

Oakmont Country Club doesn’t yield much, especially holes-in-one. Prior to Friday, just one competitor in nine previous U.S. Opens at Oakmont had recorded an ace. That was Scott Simpson on the par-3 16th hole during the first round in 1983.
