The 2nd seeded Australian Stewart Boswell was the biggest casualty of the 1st round of the Irish Open. France’s unseeded Mathieu Castagnet (pic) fought back from two games down to beat Boswell, the world No18, 9-11, 4-11, 11-4, 11-4, 11-5. Castagnet now takes on Spanish qualifier Borja Golan for a place in the semi-finals. Golan, a former world no.10 making his comeback after a knee injury, despatched Hungary’s no.7 seed Mark Krajcsak 11-7, 11-8, 11-5. A qualifier is certain to make the last four after Gregoire Marche and Bradley Hindle meet in the quarter-finals. Frenchman Marche downed 6th seeded Italian Davide Bianchetti, while Malta’s Hindle recorded a notable upset when he beat rising Swiss star Nicolas Mueller, the no.4 seed, 12-10, 12-10, 6-11, 4-11, 11-5 in 68 minutes.
