Sam Burns leads the U.S. Open at Oakmont after a stellar second round 65, putting him on pace for a record-breaking strokes gained total. Only three players are under par after a challenging two days where the course proved brutally difficult. Many prominent players missed the cut, including Bryson DeChambeau and Phil Mickelson. The extremely tough conditions resulted in a record-breaking scoring spread between the best and worst rounds. Play was suspended due to lightning, resuming Saturday morning.
