An umpire is judged by making the right decisions and his sensitivity dealing with players and cooperating with other officials. Other tasks may be considered as minor. However, watching matches I regulary notice how bad some umpires are in pronouncing the players name. Actually not only 'some' and even in the biggest tournaments. Most players politely ignore the miss pronounciation or sometimes you can see a double just a bit amused and smiling to each other. To me, checking out the right pronounciation of players names would be a sign of acknowledgement and respect. It takes just a minute. Wrong pronounciation - even of well know international names - seems a bit awkward if not ignorant. Introducing players is not the umpires main job and may be negligible. Umpires have not to be multilingual too. But a little pronounciation check ahead of the introduction would indicate more respect to players and their teams.
