Scotland’s Colin Montgomerie shot an even par 71 to finish at 6-under par after two rounds and keep his lead at the U.S. Senior Open at Oak Tree National in Edmond.

Montgomerie leads Scott Dunlap by one stroke going in the third round on Saturday.

At several points Friday, Montgomerie and Dunlap were tied for the lead with Bernhard Langer, but the German bogeyed three of his final four holes to finish at 4-under par with a 69.

Langer is tied with Gene Sauers at 4-under par.  

Sauers shot a 69 as well on Friday.

It was another tough day for golfers with Oklahoma ties.

None of the nine with ties to Oklahoma shot under par, and several missed the cut.

Former Oral Roberts University golfer and current Stillwater resident Bill Glasson is the best of the Oklahomans at 4-over par after a 73 on Friday.

Oak Tree golfers Willie Wood and Bob Tway are both at 5-over par, both shooting 73 in the second round.

Gil Morgan is 6-over par after a 76.

Scott Verplank missed the cut by one shot, shooting his second straight 75 to finish at 8-over par.

Other Oklahoma-related golfers who missed the cut included former OSU golfer Dave Eichelberger at 11-over, Oklahoma City qualifer Rocky Walcher at 12-over, and former OSU golfer and ex-Oak Tree resident Danny Edwards at 20-over.
