Ace no Kyuujitsu

Summary

After being dumped by his girlfriend, arrogant pro baseball player Hidaka ends up alone on a twenty-day cruise. Drinking too much, getting into fights and trying to pick up girls, he's already in hot water with the eccentric captain of the liner when he rudely refuses a young boy's request for an autograph. The boy happens to be the captain's son, and this incident is the last straw, leading the captain to decide his ship would be better off without the cocky ace.
