Koepka’s 63 on Thursday and Friday 65 start is like a football team (American football) taking a 28-0 lead to the half. A little comeback is expected, but four touchdowns is typically an insurmountable lead. Koepka’s hot start was enough to hang on–even after bogeying five of the last eight holes.

Two factors made it tough for Koepka to hang on: it’s difficult to keep the foot on the throat with a huge lead (seven shots) and it’s hard to play with someone that shoots 81 (Harold Varner III).
Jordan Spieth’s game continues to veer for the light–he finished T3 for $575,500. Koepka’s first place finish was good for $1,980,000.

The two-time U.S. Open defending champion goes for a third on June 13 at Pebble Beach Golf Links.
