Defending champion and No. 1 seed Robbie McCarthy Jnr. successfully retained his GAA/O' Neill's Irish (40X20) National Championships Men's Open Senior singles title by easily defeating Michael Gregan in a one-sided final clash at Kingscourt, Co. Cavan on Saturday.

McCarthy Jnr. was well in control throughout both games and despite some stern resistance from Gregan, the Westmeathman blitzed through to close out 21-9 in both games.

Meanwhile, in an all-Antrim clash in the Women's Open Senior Singles final, rising star Aisling Reilly caused an upset when she defeated defending champion and No. 1 seed Fiona Shannon in a tense encounter.

Reilly began explosively, storming into a commanding 15-3 lead in the first game before Shannon clawed her way back into contention and narrowed the gap to 18-14. But that was as near as Shannon got, Reilly pointing three times in succession to close out on a decisive 21-14 scoreline.

The second game proved to be a much more one-sided affair, as Reilly produced her full armoury of pinpoint kill shots and smooth passing shots to win 21-2.

Legendary Kilkenny handballer Michael "Ducksy" Walsh added yet another title to his illustrious list, when he bagged the Masters "A" Singles crown, easily defeating Meath veteran Tom Sheridan.

Walsh was well in control throughout and despite some dogged resistance from a determined Sheridan, the Kilkenny maestro closed out 21-12, 21-11 to extend his unbeaten run on the Masters (40+) circuit.
