Three-time defending LPGA champions Juli Inkster and Dottie Pepper defeated Grace Park and Kelli Kuehne 4-and-3. Jack Nicklaus and Tom Watson birdied five of their final six holes to better Gary McCord and John Jacobs 4-and-2 in the Senior Tour division, while Fred Couples and Mark Calcavecchia topped Jean Van de Velde and Steve Flesch 4-and-3 in the PGA Tour division.
Inkster and Pepper will now face Annika Sorenstam and Lorie Kane in the finals. Sorenstam and Kane defeated Meg Mallon and Beth Daniel 2-up.
Inkster and Pepper won this event - formerly known as the Diners Club Matches - in 1996, '97 and '99 (no tournament contested in 1998). They haven't lost a match as a team since 1995, compiling a career record of 13-3.
Nicklaus and Watson will once again battle Bruce Fleisher and David Graham in the Senior Tour finals. Fleisher and Graham won the final two holes on Saturday to defeat Dana Quigley and Allen Doyle 2-up.
Last year, Nicklaus and Watson won the Senior division by defeating Fleisher and Graham 1-up in the finals. Nicklaus and Watson have combined to win 150-career PGA/Senior Tour titles, including 34 major championships.
On the PGA Tour, Calcavecchia and Couples will now face Tom Lehman and Duffy Waldorf. Lehman and Waldorf blitzed Phil Mickelson and Rocco Mediate 6-and-5 in the semifinals.
Each of the three tours plays the par-71 Pelican Hill layout from separate tees. The PGA Tour portion of the event is contested over 6,897 yards. The Seniors play over 6,697 yards, and the LPGA is over 6,346 yards.
