Hi, and welcome to Wikipedia. Thanks for your edit to Fastest recorded tennis serves, but unfortunately I had to undo it. You added a line about Bill Tilden, but he's already mentioned in the article, which explains why he's not included (the measurement of his serve speed is of questionable accuracy). You also added a line saying that Andy Roddick hit a 165mph serve, but no source was provided. On Wikipedia, contentious claims like that need reliable sources to be included in articles (see that page for more information).

I hope that's clear. If you have any comments, you can reply on my talk page or on the talk page of the article. If you need help, you can go to Help, or type. Happy editing! Robofish (talk) 22:15, 6 July 2015 (UTC)
