Is it my imagination or does everyone seem to be serving a lot harder all of a sudden? It seems like only a year or two ago that everyone was heaping praise on Sampras' serve, how he was the only one who could come up with second serve bombs consistently. Now Sampras serve would appear to belong in the 'slightly above average' category, like say Federer. Roddick is hitting a lot of second serves well over 120mph. Even an average server like Heman is hitting all of his second serves well over 100mph. This was unheard of even for the best servers during the mid 90's. Is there a steroid problem or are the radar guns juiced up these days?
