You need to go and have a look at template hierarchy for custom post types. I believe your custom post type is tennis. So you would make a copy of your theme’s archive.php template and call it archive-tennis.php You can now style that template to your liking.
Just remember, you don’t need to add or change any specific code inside your new template to specify your CPT. WordPress will exactly know it should use archive-tennis.php when the custom post type tennis is clicked
