Roísín Ní Riain aiming to build on her fourth place for remaining races

Fourth. But not the usual stomach-sinking fourth. Not a fingertip fourth. This was a different, more palatable type of fourth.
Roísín Ní Riain turned fifth at the halfway mark in the S13 100m butterfly final and proceeded over the second half of the race to shred the gap on the Uzbekistan swimmer to her immediate left. It was a gap that kept shrinking all the way to the wall. A gap still remained, though, when the wall did come.
