Sycerika McMahon fails to progress in 100m European heat
Northern Ireland swimmer Sycerika McMahon finished last in her 100m breaststroke heat at the European Championships in London on Tuesday.
The Portaferry swimmer will now focus on her main event, the 200 individual medley, which starts on Wednesday.
Fiona Doyle qualified 12th from the 100m breaststroke heats and then went on to progress to the final as she clocked 1:07.99 in her semi-final.
Shane Ryan finished eighth in the 100m backstroke final in 54.49.
Ryan, competing in his first championship for Ireland since his switch from his native USA, would have earned bronze if he had been able to produce his season's best of 53.93.
The American-born swimmer will be in action in the 50m backstroke on Wednesday.
Limerick swimmer Doyle was delighted with her performance in qualifying for Wednesday's 100m breaststroke final.
"Once I had the heat swim out of the way I knew exactly what I needed to do," said Doyle.
"The race again still wasn't perfect but it was miles better than this morning and we know there's more to improve on so I'm really looking forward to tomorrow."
Portaferry swimmer McMahon competed at London in 2012 but still needs to swim the qualifying standard for this year's Games.
In 2012, McMahon became the youngest Irish swimmer to win a medal at a major event when she took silver in the 50m breaststroke at the European Championships in Hungary.
On Tuesday, Jordan Sloane of Bangor was third in his 200m freestyle, but outside the Olympic qualifying time. The 22-year-old is a reserve for the semi-finals.
