This trick is performed by going to to your 'Mange Roster' menu and editing the player you don't want to lose to free agency. For example, if it is Carlos Zambrano you want to keep scroll to his contract and where you see the amount of money and years he has remaining lower the amount of money and add as many years as desired.
