Sycerika McMahon missed out on a second medal at the European Short Course Championships as she took fourth in the 100m breaststroke final on Sunday.
Yet again, McMahon set a new Irish record as she improved her own mark by .28secs as she clocked 1:06.18.
However, she was pipped for bronze by Spain's Marina Garcia Urzainqui (1:05.82) as winner Rikke Moeller Pedersen won in a European record.

Pedersen improved her own championship record and also set a new European mark as she won in 1:04.12 which left her well ahead of Chocova (1:05.50).
