Gurazeni: Money Pitch

Bonda Natsunosuke (26, single), is a left-handed relief pitcher for the professional baseball team, the Jingu Spiders. He became a pro right after high school and now in his 8th year makes 18 million yen a year, and is not what you'd call a "first rate player." He's approaching 30 but still believes he can hit his prime and find "money buried in the grounds."
