This week, I lost my USTA 4.5 singles badly. I was playing up from 4.0, but our team is a high level 4.0 team.
I finished my match and was chatting with my opponent. We ended up drilling some crosscourt forehands for about 15-20 min., then exchanged numbers to call each other for further drilling. We discovered that we both like to drill rather than always play sets in practice.
No drama, no hooking line calls, no nothing - and possibly a newfound drilling partner.
Just as an example of my experience. Good tennis, good sportsmanship - or sportswomanship. This has been what I have experienced so far. Thought this might balance out the horrible experiences posted so far.
