IMG Academy alum Cheng-Tsung Pan has the chance to do something that no amateur golfer has done since the 1930s.
That's win the United States Open.
The University of Washington rising junior put himself in contention when play was suspended due to darkness for a second consecutive day at Merion Golf Club outside Philadelphia.
Pan sits even-par for the tournament through nine holes in his second round, which is one off the lead shared by Phil Mickelson and Billy Horschel.
But unlike Pan, those two players completed their second rounds Friday. Pan must finish his second round Saturday morning, and should he remain under the projected cut line he'll continue play in the final two rounds Saturday and Sunday.
Pan doesn't have any bogeys on his card in the second round and has two birdies. They came on the par-5 second hole and par-4 fifth.
Pan's final hole Friday was the par-3 ninth, and he lagged a lengthy first putt close to the cup and tapped in for par to close the day.
