WALTON ON THE HILL, England – Mark Calcavecchia surrendered a three-shot cushion to finish the third round of the Senior British Open on Saturday tied for the lead with fellow American Russ Cochran and South Africa’s David Frost.
Calcavecchia, the overnight co-leader, was in cruise control at 10 under with six holes remaining but made a triple-bogey 7 at No. 13 after driving into the heather and then dropped another shot on No. 16.
A birdie at the final hole left the 1989 British Open champion at 7 under. Frost shot a bogey-free 66 – tied for the week’s best round – and Cochran had a 67.
Corey Pavin and Barry Lane each shot a 69 and are a shot back of the leaders, with three more Americans – Chip Beck, Mike Goodes and Lee Rinker – at 5 under.
