This video shows 22-time Olympic medalist Michael Phelps nailing an approx. 150-foot putt during the Dunhill Links Championship in St. Andrews, Scotland.

Not just any putt - arguably the longest putt ever recorded on TV - the previous "record" was a 99-footer set by broadcaster Terry Wogan in 1981 (see video below).

Phelps' putt took 17 seconds to drop.  It travelled almost the length of an Olympic swimming pool.

His playing aprtner was Paul Casey (who recently competed in the Ryder Cup).  Casey's caddy believed the putt to be 51 yards, or 153 feet.

The former "longest putt ever recorded" by Terry Wogan
