fight money
n.— «After contributing to a Hanshin victory, Igawa’s manager would frequently hand him an envelope stuffed with yen, usually the equivalent of about $1,000. Igawa was free to spend the money as he liked. He usually saved it and kept the envelope as a souvenir. The financial exchange, which is separate from a player’s salary, is common in Japanese baseball and known as kantoku shou, which, translated literally, means manager prize. The foreign players in Nippon Professional Baseball commonly refer to it as fight money.» —“More Than a Handshake Deal for Japanese Baseball Players” by David Picker New York Times Apr. 17, 2007.
