WALTON ON THE HILL, England — Mark Calcavecchia surrendered a three-shot cushion to end the third round of the Senior British Open tied for the lead with fellow American Russ Cochran and South Africa's David Frost.
Calcavecchia, who has been in a three-way share of the lead after every round this tournament, was at 10 under with six holes left Saturday before imploding. A triple-bogey 7 at No. 13 was followed by bogey at 16, although the 1989 British Open champ made birdie at 18.
Calcavecchia, trying to become the fourth player to capture the British Open double, shot par 72 to finish at 7-under 209. The stumble by the former University of Florida standout gave a bunched-up field renewed hope in the Champions Tour's third major of the year.
"(Saturday) was exactly what's been happening to me all year," said Calcavecchia, winless in 2011. "I drive it great for a while, and then I just lose it. That's what I was worried about — and then it happens to me. I have to figure it out by (today).
"I lose faith in myself. I could hit 20 perfect drives in a row and then hit one dead left and one dead right. … I can't regroup."
Frost shot bogey-free 66, while Cochran's 67 included double-bogey 6 on No. 14.
American Corey Pavin (69) and England's Barry Lane (69) were a shot behind. Three-time winner Tom Watson (69) was three strokes back.
Lee Rinker (74) and part-time Dunedin resident Rod Spittle (75), who shared the overnight lead, struggled but are two of 12 players within three shots.
PGA: Bo Van Pelt birdied four of his last five holes to shoot 5-under 65 and finish with a one-stroke lead at 5-under 205 after three rounds of the Canadian Open in Vancouver. Canadian Adam Hadwin (68) missed a 12-foot birdie putt on 18 to finish alone in second.
LPGA: Japan's Ai Miyazato took a two-stroke lead after shooting 5-under 67 in the third round of the Evian Masters in Evian-les-Bains, France. Miyazato made five birdies to close at 13-under 203. Stacy Lewis (69) and Angela Stanford (69), Japan's Miki Saiki (70) and South Korea's Ran Hong (67) were at 11 under. Seminole's Brittany Lincicome (72) was tied for 21st at 5 under.
U.S. Junior Amateur: Jordan Spieth, 17, of Dallas beat Chelso Barrett, 16, of Keene, N.H., 6 and 5 in the 36-hole final in Bremerton, Wash., to join Tiger Woods (1991-93) as the only multiple winners of the event. "Any time you can be compared to any of Tiger's golf accomplishments is very special," said Spieth, who won in 2009.
European: Sweden's Alexander Noren shot a course-record 9-under 63 to extend his lead to 11 after the third round of the Nordea Masters in Stockholm. He made seven birdies and an eagle in closing at 20-under 196. Bubba Watson (69) was in second.
