I recently bought a copy of the labor agreement MLB reached in 1990 to end that year’s lockout. It’s about 100 pages long, in a spiral notebook. Here are two excerpts from the player’s contract that’s printed near the end of the agreement:
The Player agrees to perform his services hereunder diligently and faithfully, to keep himself in first-class physical condition and to obey the Club’s training rules, and pledges himself to the American public and to the Club to conform to high standards of personal conduct, fair play and sportsmanship.
The Player represents that he has no physical or mental defects known to him and unknown to the appropriate representative of the Club which would prevent or impair performance of his services.
