Ellen Walshe on crest of wave at short-course World Championships, Danielle Hill misses out

Ellen Walshe set two Irish records as she booked places in a semi-final and final on the first day of the World Aquatics Swimming Championships (25m) in Budapest.

The Dubliner took over a second and a half off her own 200m individual medley national record as she qualified sixth for tonight's final (5.01pm) in a time of 2:06.50.

Half an hour earlier, Walshe lowered her senior 50m butterfly record from 25.90 to 25.65 seconds and advance to this afternoon's semi-final (from 4.43pm) in 14th place.

It wasn't such good news for Olympian Danielle Hill, who failed to progress from the heats of her main event, the women's 100m backstroke; her third-fastest time of 57.95 seconds (sixth in her heat) was only enough for 19th overall.

Hill was a silver medallist at the European short-course championships in June in a time over two seconds slower.

Galway's John Shortt lowered his own recent junior Irish record to 51.21 seconds but also fell outside a top-16 place in the men's 100m backstroke while Max McCusker (23.09) was 32nd in qualifying in the men's 50m butterfly
