With the Ultimate Tennis Career mod your sims can work their way up through a dozen different levels of tennis expertise, until they’ve become the GOAT. From there they can move on to teaching others with the Coach career branch, or take an easy retirement and gab their way through the Commentator branch instead. All in all there are 17 steps to get from the bottom rung to the top of either branch, so your sim will definitely be putting the work in!
