Brian Henninger, winless on the PGA Tour since 1994, carved out a 6-under-par 64 in yesterday's third round for a three-stroke lead after three rounds of the John Deere Classic in Coal Valley, Ill.

Rain overnight made the greens accessible and the players took advantage with 299 birdies.

Henninger, one of 31 players called off the course because of threatening weather Friday night, came back early this morning and completed a second-round 63 to trail leader Mike Brisky by one stroke. His 64 yesterday afternoon allowed him to tie the tournament's 54-hole record of 193 set by Blaine McCallister in 1987. The 72-hole record is 21 under by David Frost in 1993.

Henninger dropped three strokes behind with a bogey at the par-4 fourth hole, then strung together three birdies and an eagle over a five-hole stretch beginning at the par-4 seventh, where he made a three-foot putt for birdie.

SENIORS: Hale Irwin shot a 68 and held a one-stroke lead over fast-closing David Graham after two rounds of the Burnet Senior Classic in Coon Rapids, Minn.

Irwin led by six strokes after 15 holes, but bogeyed two of the last three holes. Graham birdied three of the last four holes for a 68 that left him at 11-under-par 133 for two rounds over the 7,030-yard Bunker Hills Golf Club course. . . .

In the Senior British Open, Bob Charles and Christy O'Connor Jr. made charges in Portrush, Northern Ireland, to the top of the leader board.

Charles took the lead by shooting a 5-under-par 67. He has a 212 total for the 54 holes. O'Connor shot a 68 and moved into second place, one stroke back.

LPGA: Marnie McGuire shot a 7-under-par 65 to take the lead after the second round of the Giant Eagle LPGA Classic in Howland, Ohio.

McGuire is one stroke ahead of Jackie Gallagher-Smith, Missie McGeorge and Michele Redman.

McGuire shot a 6-under 30 on the back nine, tying a tournament record for nine holes.
