I also "cheat" a lot by watching some matches for 10/15 minutes at Wimbledon. Not too bothered about women but out of the top names - Serena Williams, Ivanovic, Kuznetsova, Hantuchova and Dementieva.
The boys - Roddick, Andy and Jamie Murray, Djokovic (training), Davydenko, Gonzalez
, Monfils, Cilic, Simon, Berdych, Wawrinka, Hewitt, Ljubicic, Isneer, Andreev, Tipsarevic, Nalbandian, Baghdatis, Safin, Korolev, Tursunov, Agassi and guys like Ram but I couldn't list them all.... bit of a tennis junkie
The one that pains me the most is I've never got the chance to see Rafa live... one day
