Tennis hitting session 4.0 vs 3.5. Me and a teammate stayed after a USTA match to get some extra hitting in. After a warm up we played some points out.

Let me know who the 4.0 is.<br />...<br /><a href="https://www.youtube.com/watch?v=XaDFIz2ecvI" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=XaDFIz2ecvI</a>
