Last weekend 13 year old Sam Dailley of Plymouth Leander destroyed the national age group mark in the boys short course 50 butterfly posting a time of 26.43, lowering the previous record by almost a full second.
Dailey appears to be taking some lessons from teammate Ben Proud when it comes to record breaking performances.
In the summer at the British Gas Age Group Championships Daily broke both the 50 and 100 butterfly age group records posting a 26.80 in the 50 and 58.08 in the 100.
