The last time trials ahead of the National Championships produced two junior records.
One came from Neptunes swimmer Neil Muscat.
He improved on his previous Group C best of 25.55 seconds in the 50m freestyle registered in April when on Saturday he clocked 25.14 seconds.
Kristina Fino, of Sliema ASC, swam the 50m butterfly in 32.84 seconds to clip 0.04 of a second off her best national age-group time also obtained in April.
