 If you liked
Tennis no Oujisama

Baby Steps 2nd Season
|
Both are top notch tennis anime.
Price of tennis is more drawn out and places a focus on many players whereas Baby Steps is more concise and focuses solely on the protagonist.
Baby steps have regular humans playing tennis unlike in prince of tennis where the players are all gods who can jump 20 feet high, a la kuroko no basket. This may be a determining factor for many.
On the whole both are must watch sports anime.
