Colin Montgomerie remains in front after the second day of action at the U.S. Senior Open.
The Scotsman had an even-par 71 on Friday and is 6 under for the tournament, good for a one-stroke lead over Scott Dunlap.
A few golfers remained on the course as of 8 p.m. EDT, but the leaders had finished.
Dunlap had a 68 in the second round. He birdied Nos. 2, 5 and 7 on his way to a 3-under 32 on the front nine.
Bernhard Langer took sole possession of the lead with a birdie on 14, but netted bogeys on 15, 16 and 18 to finish tied for third at 4 under. He is tied with Gene Sauers, who shot 69 on both the first two days.
