Among ATP and WTA , who has the most boring game of all time. The players should have won atleast a Slam/year end masters to qualify for this "Most boring" title. It is even hard to define what constitutes as Boring. Some might say predictable game (aka Roddick who mostly wins by bludgeoning serves) is boring. Then some have said federer was boring when he was his dominant best around the 2007's.Some have said Perrera was boring because he just lefty hooks his forehand into opponents backhand. Some have called Pete Sampras boring because he doesnt show his emotions. I dont find any of the above to be one dimensional.But others may or may not agree. My vote goes for Thomas Johansson but that could be because i know so little about his game. Update : I happened to watch a few more of Thomas Johansson after some of the posts here and i dont find him boring any more. I guess then i dont have any one particular player (slam winner) that is boring.
