there's a lot of sporty scenes in School Rumble. couldn't tell ya off the top my head what episodes they are, however the episode titles are pretty specific.
kuroko no basket
Medaka Box has a few sport-ish scenes, mostly in the earlier episodes
Didn't a new Prince of Tennis season come out sometime recently-ish?
Haruhi has a baseball episode
And Death Note has that epic Tennis match xD
I'm surprised nobody said this already but, Inazuma Eleven. Soccer Show. There was also a brutally hilarious Rugby episode of Full Metal Panic Fummofu!?! (spelling?) And Kenichi the Mightiest Disciple.
