Amelia Kane demonstrated her potential when finishing off the Irish long course championships with gold in the 1550m freestyle final in the National Aquatic Centre.
After a fine week in Dublin, the Ards teenager is now in line to represent Ireland at the World and European Championship junior championships this summer.
The 16-year-old Ards swimmer, who had earlier in the week picked up bronze in the 400m individual medley and 200m freestyle, took 1500m gold in 17:42.49.
It proved to be another good meet for Ulster swimmers as Danielle Hill set a new 50m backstroke record of 28.64 on Friday night and followed that up with 100m gold on Saturday, while Bangor's Jordan Sloan sparkled in the 200m freestyle.
Sloan came close to his 200m free Irish record in the morning heats, swimming a second fastest time ever of 1:47.63. Returning to the pool last night for the final, Sloan took the Irish title in 1:48.44 ahead of fellow Ulsterman Jack McMillan, 1:48.56 and Robbie Powell, 1:49.65.
Brendan Hyland took his fourth Irish title of the championships in the 100m butterfly, having set new records in the 200m butterfly and 200m IM.
Carrick's Conor Ferguson added gold to the 50m backstroke title and 100m silver in the 200m back last night.
Ferguson touched in 2:00.07, ahead of team mate Sean Scannell. Scannell, who clocked 2:04.40, was under the consideration time for European Junior Championships.
Breaststroke ace Darragh Greene collected the Swimmer of the Meet Trophy.
Greene's 200m breaststroke swim on Thursday was the closest time to a world record at the event in 2:10.05, breaking Andrew Bree's 11-year best.
