KAUAI, Hawaii, Nov. 20 (UPI) -- Retief Goosen of South Africa carded a 6-under-par 66 on Tuesday for a one-shot lead over three-time defending champion Tiger Woods midway through the 36-hole PGA Grand Slam of Golf.
The unoffocial event gathers the season's four major winners.
Goosen won the most memorable of the Grand Slam events, claiming the U.S. Open at Southern Hills in an 18-hole playoff with Mark Brooks after double-bogeying the final hole of regulation.
The soft-spoken Goosen made over $1.17 million in just nine PGA Tour starts and won the Order of Merit on the European Tour with nearly $2.86 Euros.
Goosen is coming off a win at the World Golf Championships-World Cup in Japan, where he teamed with countryman Ernie Els to claim a four-way playoff.
In that event, Woods forced himself and teammate David Duval into the playoff with an eagle chip on the final hole of regulation. The Masters champion continued his solid play Tuesday, shooting a 5-under 67.
Duval, who claimed the British Open in July for his first major crown, stumbled to a 4-over 76 at the Poipu Bay Golf Club.
PGA Championship winner David Toms is third after carding a 68.
