For three seasons, a player is committed to the team that picks him. Contracts are renewed on an annual basis. After three years, a player must either be on a team's 40-man roster, implying he has a major league contract, or be eligible for the Rule 5 draft (see below). If a club loses interest in a player after picking him in the draft, they can release him without penalty. In addition to being placed on a team's 40-man roster, a player can be assigned to a minor league camp affiliation where he will spend some time with each team's minor league affiliate. For example, a player could be assigned to a Class A short season team and play there for several months before being promoted to a full-season league team. This allows teams to monitor how a player performs in both low-pressure situations and higher-pressure games. A player who is not on a major league roster by April 1 needs to be offered a minor league contract or allowed to enter the 2005 draft. If a player refuses a minor league contract, his rights can be drafted off of him. This happened to José Guillén when he refused a minor league deal from the Chicago White Sox and was picked up by the Tampa Bay Devil Rays. The draft consists of five days of intensive amateur scouting leading up to the first day of the draft. Teams can trade picks, but cannot give them away freely.
