Naas' Conor O'Rourke warmed up for the West of Ireland Championship by winning the French International Foursomes title with Tommy O'Driscoll at Crécy Golf near Paris.
The reigning St Andrew Links Trophy holder and France-based Alps Tour professional O'Driscoll topped the qualifiers for the Trophée Royal Blackheath with a two-over par 74.
They then won four matchplay encounters, beating Christophe De Grancey and Luca Binaghi one up in the semifinals before defeating Frédéric Lacroix and Hugo Rouillon on the 19th in the final.
O'Driscoll and O'Rourke were two up with two to play but lost the 17th and 18th to pars before holing a 30 footer for a winning birdie at the first extra hole.
"The Irish were very solid," Rouillon confessed. "They holed 15 and 18 footers on the eighth and ninth to go one up and while we played well on the back nine, we didn't hole the putts."
