Jeff Salzenstein was always one of my favorite players to watch. He was a perennial Challenger player, only able to break into the tour's ATP tournaments on rare occasions like when he'd qualify at the U.S. Open or the Australian Open. But he had a love for the game, a dedication and an ability to fully immerse himself into his career. The fact that he'd become the second player ever in the history of the game after Dick Norman to break into the Top 100 for the first time after the age of 30 only demonstrates Salzenstein's determination and efficacy as a player. Anyone who saw Salzy, as he was known, play knew that his calling card was his serve. He had a booming lefty serve and was able to clock 136 mph at the age of 32. He recently had an interview from Korea with Sam Groth, an Australian who recently broke the fast-serve record with a 163 mph bomb, on his popular web site. So Salzy is up on everything big about developing a service bomb.Here's a video of a Salzy service tip.http://www.jeffsalzensteintennis.com/tennis-kick-serve-drill/Go on to his site and you can access more valuable service tips:http://jeffsalzensteintennis.com/go/tennisprose_leaderbaord_136mph.htmlhttp://jeffsalzensteintennis.com/go/tennisprose_leaderbaord_136mph.html
