Matthew McMillan, from Leslie, who swims with InCAS and is also a member of the Scottish National Junior Team, rose to the challenge in a tremendously exciting 200M butterfly final.
He swam an incredible personal best of 2:09.83 to secure a bronze medal and that elusive podium finish.
Matthew said: “Swimming in arguably one of the toughest events in a field amongst the fastest boys in the country was always going to be a challenge and to leave Sheffield with a medal and huge smile was a fantastic finish to the season.”
Coach Barry said: “His outstanding performance was a fitting achievement and reward for all his hard work in and out of the pool.”
