Tennis Ireland has appointed Garry Cahill as its new Davis Cup captain. Cahill has been employed as technical director with Tennis Ireland for the past seven years and has worked with Ireland’s top players such as Conor Niland, Sam Barry and Amy Bowtell. He replaces Sean Sorensen. Ireland plays Luxembourg in Dublin on the March 4-6 and should it win the tie, could play Britain at home in the second round.—Matthew Cronin
