There were two Irish records set in the evening session at the Irish Winter Meet at the National Aquatic Centre in Dublin, to add to a short course best in the morning session of the three-day competition.
The event, for which there are no medal presentations and which is for Irish elite swimmers at national and Paralympic level only, is broken up into two distinct sessions, with short course (25m pool) heats in the morning and long course (50m pool) finals in the evening.
Twenty-year-old Bangor swimmer Jack McMillan broke his own Irish 200m freestyle short course record in the heats, clocking one minute 42.99 seconds, cutting 0.2 of a second off his own previous best time set in 2019.
McMillan then broke Jordan Sloan's Irish long course record in the evening session with a time of 1:47.19, as Sloan filled the runner-up spot.
The second Irish record of the evening session went to Brendan Hyland, who broke his own 100m butterfly time in 52.58.
The Tallaght swimmer was paced all the way to the touch by Shane Ryan as Hyland hunted down the Irish Olympian over the final 10 metres in the race of the night.
In the 100m breaststroke, Eoin Corby beat Darragh Greene to the touch in the heats having beaten Greene in the 50m breaststroke on Thursday night.
However, in the final Greene, who swam for London Roar in the recent World Swimming League, got the better of the young pretender to win in 60.52.
Greene is the only Irish swimmer to have swam a consideration time for the Tokyo Olympics so far.
Larne's Danielle Hill broke the minute mark in the 100m backstroke heats and doubled up to win the long course decider.
Hill was also the fastest swimmer in the 100m freestyle heats in 55.17 seconds, but lost out to 19-year- old Vicky Catterson in the evening event.
Seventeen-year-old Ard's swimmer Amelia Kane was the dominant competitor in the 200m butterfly and 400m freestyle finals having been fastest in both events in the heats this morning.
Paralympian swimmers Ellen Keane (2:44.86) and Nicole Turner (3:16.99) also competed in the 200m individual medley having come though the morning heats, with Bangor’s Julia Knox taking the overall win in 2:20.98.
