Tallaght's Brendan Hyland smashed the Irish senior record for the men's 200 metres butterfly on the opening day of competition at the world short course swimming championships in Hangzhou, China

Hyland broke his own Irish record by over three seconds, finishing 10th overall in 1:53.19 seconds.

However, only the top eight swimmers advance to the final as there are no semi-finals in 200-metre events at the championships.

Conor Ferguson also set a new Irish record in the heats of the men's 100 metres backstroke in 52.04 seconds, cutting .36 of a second off his own Irish best time, but also failed to advance to a semi-final berth as he was ranked 24th.

World Youth Olympic Games silver medallist Niamh Coyne (31.42) and Darragh Greene (58.91) set personal best times, in the women's 50 metres breaststroke and men's 100 metres breaststroke respectively, but finished in the middle of the field.

Hyland is the only Irish swimmer in action tomorrow when he goes in the heats of the men's 100 metres butterfly.
