We're approaching the middle weekend of the AO and so far I haven't seen a beep of regular umpires Mohammed Lahyani, Enric Molina and Cedric Mourier, to name three. Where are these guys? I'm missing Jimmy Smits/Quentin Tarantino lookalike Lahyani the most. It isn't the same without his emphatic "Thir-TAY-fif-TEEN-UH"... Veteran umpire John Lloyd, sorry, Gerry Armstrong called the Fed/Davydenko match tonight. He was working Sydney last week as well. Isn't he supposed to be an ATP backroom guy nowadays? Does the fact they wheeled Armstrong out to call matches mean Lahyani, Molina and Mourier et.al have skipped this year's AO ??
