Tony Finau carded a blistering 8-under 64 in Round 3 at Augusta to grab the clubhouse lead at 11-under par.
Finau's 64 marked the third 8-under turned in on Saturday, breaking the previous record of only one 8-under-or-better round in any single Masters tournament.
Additionally, from 1934 to 2018, there had only been two instances in which a player carded a 64 or lower in the third round.
Patrick Cantlay fired the first 64 of the day, which Webb Simpson later matched.
