Toledo, OH (Sports Network) - Olin Browne had five birdies on the back nine on Saturday en route to a six-under 65 and a two-stroke lead after three rounds of the U.S. Senior Open.

Browne finished 54 holes at 15-under-par 198 and set a couple of records along the way.

The 52-year-old became the first player in U.S. Senior Open history to post 29 for nine holes. Browne had five birdies on the back nine to card that 29 at Inverness Club.

Browne also set a new 54-hole scoring record with his total of 198. Simon Hobday owned the old record of 199, which he posted in 1994 when he won the U.S. Senior Open at Pinehurst No. 2.

He was not alone in his stellar play on the back nine.

Mark O'Meara, who played alongside Browne, fired a five-under 66. He finished three rounds at 13-under-par 200. The duo will play together again on Sunday. O'Meara birdied three of the last four holes, but picked up just one stroke in that span as Browne birdied the final two holes himself.

Jeff Sluman matched Browne for low round of the day with his 65. Sluman moved into a share of third place at nine-under-par 204. He was joined there by Mark Calcavecchia (69), Joey Sindelar (69) and Peter Senior (68).
