At what point did the serve become the weapon it is? I heard and interview with Agassi where he said Ivanisevic was the first who could serve 20-30 aces a match. Was he the first 'big server'? Becker was known for his serve but was it really a big weapon? Even further back, the only guy I know of who was known for his big serve was Roscoe Tanner. Also, at what point where speed guns introduced into the game? I wat to make it clear that I am talking about players who have serves which get them lots of aces and unreturnables, like ivanisevic, karlovic, roddick, etc. Not somene like Macenroe who had a good serve but used it to set uo the point, he didnt directly win the point with the serve. Was Tanner the first to do this, or wasnt he at that level?
