Phillip Kent Shinnick (born April 21, 1943) is an American track and field athlete, known primarily for the long jump. He represented the United States at the 1964 Olympics. He qualified for the Olympics by finishing third at the 1964 United States Olympic Trials, where winner Ralph Boston set the world record of 8.34 m (27 ft 4+1⁄4 in), to beat the 8.31 m of Igor Ter-Ovanesyan set two years earlier and equalled by Boston a month earlier. However, on May 25, 1963, Shinnick jumped 27 ft 4 in (8.33 m) at the 1963 Modesto Relays more than a year earlier. Shinnick was credited with beating Boston at that meet, but a wind reading was not taken on Shinnick's jump. So in effect, had the jump been officiated properly and the wind legal, Boston should have been beating Shinnick's mark. Boston had problems with the wind himself. He jumped 8.49 m (27 ft 10+1⁄4 in) to win the trials, but that jump was wind aided. Boston added another centimeter to the record at the 1965 Modesto Relays.

When Shinnick jumped his 27'4" there was only one wind gauge at the meet. Shinnick was a jumper for the University of Washington, not expected to be setting a record. At the same time he was jumping on the west runway, the wind gauge was measuring a legal +1.6 mps for the 220 yard hurdles on the same west straightaway.

“They didn’t know who I was. Ralph [Boston] told me later ‘when I saw that jump, I went into shock. I just was absolutely in shock.’ And I think that the track world never recovered from that shock. They couldn’t believe the unbelievable. How could a guy who’s just twenty-years-old, and jumped in only four or five college meets in his life, break the world record?”

Meet officials voted to submit the mark as a world record, but it was not accepted by the IAAF, the world governing body. On January 20, 2016, the President of the University of Washington and Athletic Director Cohen sent a letter to Sebastian Coe, President of the IAAF. "For reasons that have never been explained to any relevant parties, the IAAF did not respond to the request for recognition as a World Record within the appropriate time-frame, and Mr. Shinnick was left with no avenue of appeal. We ask that you review and correct this injustice. " Federation disputes go to outside arbitration but the IAAF time barred this recognition so far.

“First of all it wasn’t a wind. It wasn’t even a breeze… Whatever it was, it wasn’t enough to blow out a match…even a hummingbird’s feather would have dropped to the ground without drifting in its descent at the moment young Shinnick made his phenomenal jump.”

Shinnick grew up to become an Acupuncturist and mind mapping research scientist in Manhattan. For forty years he waged a battle to get his record recognized, enlisting the support of Olympic Gold Medallists Lee Evans, Tommie Smith, Hal Connolly, and Bob Beamon. He has affidavits from virtually every person involved. He has had expert wind analysis of film of the jump done.

“I saw the attempt and it was real.”
