Professional baseball contract negotiations are often a detailed and intense affair for both baseball teams and baseball players. In contract negotiations, agents often represent baseball players and argue for the player's desired contract terms. Some contracts are very simple, covering just the basics, while other contracts may cover a wide variety of stipulations and special clauses. Players may request in contracts things such as plane tickets for personal travel, assistance for their family members, hotel suites, bonuses for performance, and many other items related to their time under contract. Signing bonuses and salary requirements are also commonly argued for in contract negotiations. Due to the rise in steroids use among professional baseball players, contracts may contain language regarding random drug testing and what penalties may be assessed in the event of a positive drug screen. Other contracts turn a blind eye to the steroid problem, allowing players to take performance enhancing drugs in secret.
