GIRL GOT GAME (Power!!), by Shizuru Seino. First published in 2000 and first published in North America in 2004.
PLOT:
Kyo's father had dreams of playing for the NBA as a young man until an injury put a stop to them. He's determined to make his daughter fulfill them at any cost, even if it means making her pose as a boy so she can attend Seisyu Academy and play on their award-winning basketball team. The only thing more aggravating for Kyo than having to pose as a boy is dealing with her moody roommate and rival Chiharu. His skills on the court are equal to hers, but his poor attitude and problems from his past threaten to sideline him before the season can even start. Can Kyo help him find his motivation?
