In the 100m final at the AAA Track and Field Championships in Bedford, Wisil was pipped on the line by Diani Walker of the Birchfield Harriers athletics club after leading from the gun, having to settle for second place in a time of 11.49 seconds.
Coach Tony Fairweather said Wisil ran well but just dipped too soon at the finish.
