Shane Ryan became the second Irish swimmer to qualify for the for July's World Championships in Gwangju, South Korea winning the men's 100m backstroke on the penultimate day of competition at the Irish Open Swimming Championships at the NAC in Dublin.

Ryan, 25, won the decider in 53.73 seconds, a new Irish senior record and well inside the Worlds qualification time. Conor Ferguson, the former World Junior silver medallist, took second place, but fell just outside the qualifying standard. Rory McEvoy of the NCD earned bronze.
