One of the perks of being on the 40-man roster is a guaranteed invite to big-league camp, which itself brings more perks: in addition to playing in the big league club’s games, they get a locker alongside current MLB players and a chance to rub elbows with some of the game’s best; easy access to the resources of the big-league club, both material and human; and, of most immediate interest for minor-league grinders, a significantly more generous per diem for food and incidentals. In addition to the 40 players guaranteed invites, every year another dozen and a half or so players are also issued invites to big-league camp.
