Just saw this guy serve for the first time at Wimbledon yesterday. He hit the biggest serve on court (132 mph). He's listed at 6'0/183 cm, but you know how height is listed. Also on court was Thanasi kokkinakis (6'4/193 cm) and austin Kracijek (6'2/188 cm), who both serve really well. I don't see how he gets the pop that he does, other than his motion is really smooth. I realize in layman tennis, 6'0 isn't short, but in pro tennis it is, yet, he still gets serious pop on his serve.
