Nancy Lopez sank a five-foot birdie putt on the first playoff hole for her first victory of the year as she defended her title in the MBS LPGA Classic yesterday in Buena Park, Calif.

The playoff victory over Cathy Gerring capped a late charge by the LPGA Hall-of-Famer. After two holes of the final round, Lopez was eight shots behind leader Caroline Keggi.

But she stormed into contention with five birdies en route to a 4-under 68 over the 6,351-yard Los Coyotes Country Club course, winning her 43rd career title. Gerring, who had a final-round 72, missed a 30-foot birdie try on the first playoff hole. They finished 72 holes at 281, 7 under par.

Keggi struggled to a 75 that left her one shot behind Lopez and Gerring at the end of regulation.

World Matchplay: Ian Woosnam beat Mark McNulty, 4 and 2, in Virginia Water, England, to win his second World Matchplay title in four years. Runner-up to Nick Faldo last year and a winner in 1987, Woosnam had McNulty chasing him almost all the way round the Wentworth course.

The match for third place between Chip Beck and Greg Norman was halved after the two remained tied through 38 holes.

PGA: In Endicott, N.Y., Nolan Henke shot a 3-under-par 68 to outlast Barry Jaeckel and hold off Mark Wiebe and take his first PGA Tour victory in the B.C. Open.

Henke, who never trailed after sharing the first-round lead with Jim Hallet, finished four trips around the En-Joie Golf Course in 268, 16 under par, three strokes better than Wiebe, who overtook Jaeckel for second when he birdied No. 18 for a final-round 64.

Jaeckel, who started the day in second and three strokes behind Henke, pulled within a stroke of the lead on the 10th hole, but lost any chance of overtaking Henke when he suffered bogeys on 14 and 15.

Seniors: In Richmond, Jim Dent came from six shots behind with a 7-under-par 65 to win the Crestar PGA Senior Classic with a 54-hole total of 202, tying the tournament record of 14 under par.

Dent, who had equaled the course record of 64 Saturday, had seven birdies in a bogey-free round yesterday that tied the record set two years ago by Arnold Palmer.

The victory was worth $52,500 and moved Dent into second place on this year's money list with more than $583,000.

The leading money-winner, Lee Trevino, shot a closing-round 67 and finished second at 203 over the 6,644 Hermitage Country Club course. That earned Trevino $28,000 and pushed his total for the year to $740,102.

South African Gary Player, who led after two rounds, had a 73 yesterday and finished third at 204.
