THE ASA Winter Championships turned into a butterfly ball for four Dorset swimmers with records galore and a brace of national titles.

Jazz McCrea became a British junior champion for the first time as she and Poole team-mates Fiona Hardie and Jacob Peters each broke two county records – all six in butterfly events.

And Swim Bournemouth’s Bath Uni student Jay Lelliott topped a string of silver and bronze medals at Sheffield with gold in a men’s 200m butterfly final in which Peters also featured.

McCrea, 15, and Hardie, 22, both erased short-course records held by the two greatest butterfly swimmers in Dorset history.

McCrea’s 100m time of 1:01.31 sliced almost a second off the Dorset junior mark set by Ferndown Otter Sam Greenep while winning bronze for Britain at the World Cup in Paris in 1994.

Greenep, who was Britain’s 100m butterfly champion that year and missed selection for the Commonwealth Games by 0.3sec, was 16 when she set her record before the maximum age for junior records was lowered to 15.

The 100m fly heats in Sheffield also saw the county senior record toppled as Hardie’s 1:00.75 lopped 0.58sec off the previous mark set by Ferndown’s Alex Savage in 2003. Hardie shaved the record again to come sixth in the B final in 1:00.74.

McCrea won her British junior title in the 50m butterfly, blasting to 27.68sec in the heats to carve half a second off her own Dorset junior record.

The time also took her into the B final against older opposition, where she came 10th in 27.74.

Hardie was also 28th in the 50m freestyle in 26.24 while McCrea was 29th, 43rd and 45th in the 100m and 200m individual medley in 1:05.20 and 2:20.88 and 50m freestyle (26.86).

Former British junior champion Peters, 16, competing in his first nationals as a senior, twice lowered his Dorset senior 50m fly record on his way to fifth in the B final in 24.53.

He also won the 100m butterfly B final in 53.62 and was eighth in the men’s 200m final in 2:01.70 after clocking an impressive 1:58.53 to come fourth in the heats.

The race provided Commonwealth Games finalist Lelliott with his only gold among seven medals, thanks to a winning time of 1:54.92.

Lelliott also won silver in the 100m and 400m freestyle and 100m and 200m backstroke, bronze in the 200m freestyle and gold in the 4x200m relay.

Bournemouth Collegiate School’s Loughborough University student Beth Aitchison was in the form of her life, winning gold in the 50m breaststroke (30.19) and 100m individual medley (1:00.35) and bronze in the 100m breaststroke (1:07.12).

All three times were inside Dorset records but did not count as she was representing her university.

Poole’s Loughborough Uni student Emily Clarke came 12th, 28th and 46th in the 800m, 400m and 50m freestyle.

Swim Bournemouth’s George Gibson was just outside the Dorset record as he came 27th n the men’s 50m breaststroke in 29.77.

BCS’s Ben Samuel was 32nd and 45th in the 50m and 100m freestyle, Kayla van der Merwe 33rd, 38th and 47th in the 50m, 100m and 200m breaststroke, Ella Chown 57th and 62nds in the 100m IM and 100m fly and Izzy Pryce 71st in the 50m breaststroke.
