M.J. Smith, rebounding from a poor start and an electrical storm that suspended play for one hour, shot 72 yesterday and took the sole lead, at 208, after three rounds at the $300,000 Ladies PGA Peter Jackson Classic on the Beaconsfield course outside Montreal.

In her ninth year on the LPGA tour and yet to win an event, Smith has led or shared first place since play started on the 6,033-yard layout. At eight under par, she stands one stroke better than Hollis Stacy, Sandra Spuzich, Donna White and Jan Stephenson.

Smith is happy over a late starting time in today's final 18 so she can watch fellow New Zealander Chris Lewis play John McEnroe on TV from Wimbledon.

She bogeyed three of the first four holes, but birdied three of the last five on the front nine and got another on the 10th, then parred in. She was on the 13th hole when the lightning came . . .

Gay Brewer staged a little back-nine charge with three birdies in four holes to move into a first-place tie with Miller Barber in the third round of the Marlboro (Mass.) Senior Classic, at 208, five under par . . .

In Oak Brook, Ill., more rain, a flooding creek and a second consecutive day's washout of Western Open play at Butler National have set up another Monday finish on the PGA Tour--the sixth this year.

Overnight storms, pouring more than two inches of rain on an already saturated course, led officials to reschedule to Sunday the second round, with 36 holes Monday. Tom Watson leads at 67 . . .

In Stockholm, Craig Stadler held a one-shot lead in the Scandinavian Enterprise Open, though he bogeyed two of the last three holes. He had 70--209, seven under par...

At Windsor, Ontario, Canadian Jim Nelford excited a partisan gallery, shooting one-under-par 69 for a three-round total of 204 and a one-stroke lead over Grier Jones in the $200,000 Essex International, part of the satellite tour . . .

Scott Inman of Springfield won two matches in the Virginia Amateur and gained Sunday's quarterfinals at Blacksburg Country Club.

LSU senior Inman beat 1970 Virginia Open titlist Rick Bendall of Lynchburg in 20 holes, then won the last two holes for a 1-up victory over ex-pro J.P. Leigh of Portsmouth.

Washington-area players eliminated in the opening round were Brian Lehnhard, George Andre, Gary Reedy and Gill FitzHugh. Glen Barrett of Manassas won his opening match, but lost his second one.
