Ken Brown, playing in the kind of rainy weather common to his native Scotland, saved par on the final hole to preserve a no-bogey 69 and hold a one-stroke lead yesterday after the third round of the $300,000 Pensacola Open golf tournament.

Brown, a former Ryder Cup player for Britain, completed 54 holes in 203, 10 shots under par on the course at the Perdido Bay Inn and Resort.

Tied for second were former PGA champion John Mahaffey, Bill Kratzert and rookie Joey Sindelar, who closed with a 66. Mahaffey had a 70 and Kratzert matched par 71 in the difficult conditions.

Danny Edwards, with a 71, and Ralph Landrum were at 205. Landrum, the leader through the first two rounds, slipped to a 73.

In the race for player-of-the-year honors, which will be determined at the close of this season-ending event, the absent Tom Watson was the beneficiary of some poor play by Bruce Lietzke and Hal Sutton and, with one round to go, moved into the lead on the points list that will determine the winner.

Lietzke and Sutton, who were eighth and ninth in scoring average going into the day's play, had 74s, which dropped them behind Watson, who moved from 10th to eighth . . .

In Narita, Japan, Seve Ballesteros shot a three-over-par 73 to keep the lead after three rounds of the $500,000 World Championship of Golf tournament. One stroke behind Ballesteros, who had a 54-hole total of 201, in the chase for the $82,000 first prize was Chen Tze-min, who shot 69.

Tom Watson shot 66 for a share of third place with Nick Price and Lanny Wadkins at 203 . . .

In Inashiki, Japan, the U.S. team took a 28-26 lead after two rounds of play in the $154,000 U.S.- Japan women's championship.
