Brooks Koepka took advantage of prime playing conditions at Augusta National on Friday morning, shooting a bogey-free round of 67 leaving him 12-under through 36 holes and five shots ahead of the field. Several golfers still have yet to tee off, including first round co-leader Jon Rahm, who is 7 under. The other first round co-leader Viktor Hovland just took the course. But they will have some serious work to do to catch Koepka. He played particularly well on the par 5s. On those four holes he was 5-under par on Friday. Koepka has won the U.S. Open and PGA Championship twice but is zeroing in on a first Masters win after finishing second in 2019. He shot 65 on Thursday to tie for the first round lead and has only one bogey in 36 holes.
