With this being said, in addition to the LA Angels needing to add a few pieces to their roster during free agency, they also must decide which players are worth keeping from their current roster.
The way things work with players who have less than five years of service time is that the team can choose to offer a player a contract or not with a given dollar amount. If the two sides agree to the financial compensation the player signs a one-year deal. If the player does not agree and the player is eligible for arbitration there is a hearing set and an independent arbiter hears the case and decides what salary the player deserves based on his stats from that season as compared to salaries of other players with comparable numbers.
