Americano Keep moving - always return to ready position. Don't let nerves freeze your feet. React quickly to their shots. Stay balanced and on the balls of your feet to change directions easily.
Aim crosscourt - less risk than down the line shots going for too much. Higher percentage play to start building confidence and consistency. Move opponents side-to-side.
Communicate with your partner - call "mine!" loudly on any ambiguous balls to avoid double faults. High five and stay positive!
Focus on getting serves and returns in play rather than going huge. Prioritize control to allow building rally points versus handing away freebies.
Most importantly, have fun! Win or lose enjoy competing and use it as a learning experience for the future. Good luck!
