I've always wondered how does one become a chair umpire in tennis, and then rise through the rankings to officiate matches at grand slams and Olympic games. My questions are answered on season two, episode four thanks to Tom Sweeney. Tom joins me and details how the offer of a free lunch set off his journey from a small town in Australia to umpiring at all four slams and two Olympics. Plus he spills the secrets on what it takes to be a great chair umpire.
