After seeing a Top Spin 4 thread and playing the game for quite a while, I wanted to share with you my recent discovery. Tennis Elbow 2011.
The game itself is decent, good mechanics and good controls once you get used to them, but what impressed me the most is the fact that it is open for modding. You can basically create new courts, player outfits and rackets, and most importantly - Animations.
Check it out:
The quality is not the best, but you can still the strokes, moment and pace resemblance.
If you are looking for a solid PC Tennis SIM, that has depth - TE11 is a great option. Highly recommend it, but ONLY modded, with correct animations.
