D.A. Weibring, the first man off the tee, shot rounds of 69 and 68, then watched and waited as PGA champion Larry Nelson's challenge fell short, enabling him to win the rain-shortened $800,000 Western Open yesterday in Oak Brook, Ill.

Weibring was in the clubhouse with a 54-hole total of 9-under-par 207 two hours before Nelson came to his 36th hole of the day with a chance to tie. But Nelson missed a 15-foot birdie putt and tied Greg Norman for second.

Weibring, 34, collected $144,000 for his first victory since 1979. The biggest check of his 11-year PGA Tour career pushed Weibring's earnings to $329,391 for the season.

LPGA: At Galloway Township, N.J., Betsy King rolled in six birdie putts on the front nine and won the $225,000 Atlantic City Classic, her fourth victory of the year, by three strokes over Nancy Lopez. With the win, King took over the lead on the money list from Jane Geddes.

King, who started the final round three shots behind Lopez and Beth Daniel, had a final-round 5-under-par 66 at Marriott's Seaview Country Club and finished the 54-hole event at 6-under 207.

Lopez (72) finished at 211 and Daniel (74) was another shot back, along with defending champion Juli Inkster.

Senior Tour: Chi Chi Rodriguez won his seventh title of the year, shooting a 10-under-par 206 to take the $300,000 Northwest Classic by a stroke over Butch Baird. The $45,000 first prize increased his winnings for the year to more than $408,000.

Women's Amateur: Kay Cockerill became only the second player in 47 years to successfully defend the U.S. Women's Amateur championship, defeating Tracy Kerdyk, 3 and 2, in the 36-hole title match at Rhode Island Country Club in Barrington. Juli Inkster won the title in 1980-82.
