Cape Town - Eight-time Major champion Tom Watson has shot his age in the second round of the Senior Open Championship at St. Andrews.
The 68-year-old rolled back the years to post a 4-under 68 on Friday.
Watson, who was a birdie short of shooting his age in the opening round, currently sits tied for sixth at 7-under at the halfway stage of the Senior Open in Scotland.
Watson will turn 69 later this year on September 4.
Only South Africa's David Frost made the cut as fellow countrymen James Kingston and Chris Williams failed to make the weekend.
LEADERBOARD: Senior Open Championship
Earlier this year at Augusta National, Watson became the oldest Masters Par-3 Contest winner.
The prime of Watson's career came in the late 1970s and '80s, when he won his two Masters titles as well as five Opens and the 1982 US Open.
Watson just missed out on a career Grand Slam, settling for a best-finish of second at the PGA Championship in 1978.
He then had an extraordinary Indian summer to his career when he nearly pulled off one of the most astonishing feats in sports history in 2009, settling for second at the Open Championship at Turnberry at age 59.
