Final-round play was called at 3:17 p.m. (ET) Sunday and will resume Monday morning at 8:00 a.m. Play was delayed for nearly four hours Sunday morning due to overnight rain.
Hale Irwin, who completed his third round of 2-under 69 Sunday, stands in first place at 7-under par after a bogey on the first hole of the final round at Valhalla Golf Club. Irwin is a three-time winner of this event, having won three straight from 1996 through 1998.
Dave Barr and Jay Haas share second place at 6 under par through two holes of their final rounds. Tom Watson (two holes) and John Harris (one hole) are one stroke further back at minus-5.
'Our hope right now is for the final round to resume Monday at 8:00 a.m.,' said Kerry Haigh, the PGA of America's Managing Director of Tournaments. 'Our hope is that we do not get too much more rain. We were unlucky and lucky today. The morning rain cells really set us back.'
The last Monday finish for the Champions Tour came at the 2001 SBC Senior Open. The 2000 Senior PGA Championship, played in Florida, was last shortened to 54 holes. That was due to seven weather delays throughout the event.
Craig Stadler stands alone in sixth place at 3 under par through two holes of the final round. Raymond Floyd (10 holes), Vicente Fernandez (five) and Walter Hall (three) are one stroke further back at minus-2.
Tom Jenkins and Gil Morgan share 10th place at 1 under par through two holes.
Because of the weather delays, Mike McCullough and Jack Nicklaus withdrew from the event on Sunday. Nicklaus is off to his home course of Muirfield Village as he is set to host the PGA's Memorial next week.
