After 54 holes, Watson was tied with fellow Americans Mike McCullough and tour rookie Craig Stadler at 205 strokes, 11 under par. Five other players are four shots back.
Meanwhile, at the PGA Greater Milwaukee Wisconsin Golf Open, Kenny Perry of the United States holds a one-stroke lead over six other players at the start of Sunday's final round.
Perry shot a 66 Saturday for a three-round score of 202, eight under par.
He has won four times in 10 tournaments when leading after 54 holes.
On the ladies' tour, two Hall of Famers, Juli Inkster and Beth Daniel, are tied for the lead after three rounds of the Canadian Women's Golf Open in Vancouver, British Columbia.
Inkster shot a five-under-par 67 in Saturday's rain-delayed third round, while Daniels carded a 69. Their 54-hole totals of nine-under 207 are two strokes ahead of fellow American Kim Saiki, who carded a 69 Saturday.
