Don’t upgrade your gear immediately after you make the required money

Again, this can get tempting as hell, and is risky too, but the meta in Tennis Clash awards high risk play. Say you are playing in Tour 2 where you need 350 coins to play a single match, and you need to upgrade to shoes which cost 10,800 coins. Now if you’ve made those coins, don’t upgrade just immediately, because you’ll be stuck grinding in Tour 2 and Tour 3 after you’ve upgraded your gear. That’s some 2 hours in gameplay and will cost you your strings. Instead, equip a high-end string and try winning a game or two in Tour 4. Only when you win and have enough coins to upgrade your gear and keep playing in Tour 4, then you should go for the upgrade.
Choose a character that suits your style of play, even if their stats are a few points lower

This aspect is underrated. If you like staying back and playing big shots, stick to Jonah. If you consider yourself an all-rounder, choose Hope. Hope as an all-rounder will play much better than Jonah as an all-rounder with the same gear, even if Jonah’s stats are 3-4 points higher overall. That is because Hope is an all-rounded player. Jonah was designed as a base-liner, so he is more efficient as that. Players’ height, stance and other aspects make a difference in how the player plays. For example, Leo is the best player if you want to go for the Serve and Volley strategy. In such a case, focus on building stats in Serve and Volley.
