Fun! I liked how the main character screws up all the time and has to build his way back up in the eyes of his coach, and how the side characters are memorably quirky and interesting.
Basically Seijun enters a new high school to play baseball at a high level, but he screws up his chances when he annoys the coach and fails a test to throw a ball a particular distance. Then, when the upperclassmen perform poorly at a game, coach gives the newbs a chance to play against the established team as a way to find talent among the scrubs, and Seijun gives his all to impress.
It's fun, with good art, and that's mostly what you need in a title like this. I wish it had some interesting female characters, though.
