Melanie Houghton, who is originally from Australia, broke the second Irish senior record of the week in the women’s 50m butterfly on day two of the Irish National Swimming Championship at the National Aquatic Centre.

Houghton, 28, who has an Irish passport and who swims under coach Paul Donovan at the NAC, broke the 50 fly record in the heats in 27.53 seconds and shaved another two tenths of a second off that time in the semi-final.

She won the gold medal in the final, but couldn’t put in another record-breaking swim, winning the gold in 27.55 seconds.

Dubliner Barry Murphy looked every bit the winner in the men's 50m fly final, but he put in a terrible finish to the race and went from first to third with the last stroke, allowing Lithuanian swimmer Deividas Marge-vicius to win the title in 24.55 seconds with Murphy relegated to bronze.

Thirteen-year-old Tallaght swimmer Antoinette Neamt, winner of two national titles yesterday, had to be content with bronze today in the final of the womens 400m IM, with gold going to Danielle Lowe of Aer Lingus.

Lowe then doubled up winning her second gold of the evening in the women's 100m backstroke in 1.04.21.

The men's 400m IM final went to Aer Lingus swimmer Ben Griffin, the 17-year-old winning in a time of 4.31.76, which qualifies him for the junior Europeans championships later this year.
