Ryan and Quinn come up short
There was ultimately no joy for the two Irish swimmers in action yesterday despite strong performances in the Aquatic Stadium.
Even though Mayo's Nicholas Quinn won his heat in the 200m breaststroke, his time of 2:11.67 was only enough for 19th fastest, with the top 16 progressing to the semi-final.
Earlier Shane Ryan also failed to match his exploits in the 100m backstroke in the heats of the freestyle 100m.
Ryan finished second in heat 3 of the 100m freestyle in 49.82, his fastest time this year, but it was the only good enough to give him 40th place overall based on times.
The USA-born 22-year-old revealed that he had been carrying a niggling ankle injury which affected his performance.
"I'm happy with the swim, we executed it well but the technique wasn't there," he told RTE.
"I screwed up my ankle a little bit yesterday so that's a factor, I can't really flex it right now, don't know what I did to it. I figure just walking around.
"But that definitely (was) a factor. I'm not making excuses but it definitely affected me a little bit. I know I can go faster, I just have to work on it. It's in that soft spot where the foot and the ankle connect. It's not fun."
Ryan's final event is the 50m freestyle tomorrow.
Fiona Doyle is back in action today for the heats of the 200m breaststroke.
