Contract extensions are all about comparables, especially when it comes to arbitration eligible players. Coming up with the relevant position, salary and service time data would have been a serious obstacle for most observers until MLBTR introduced an Extension Tracker.
The tracker shows all contract extensions, whether they cover the player's arbitration years, free agent years, or both. All the extensions are listed by date, and our filter button allows you to change the date range. You can also filter by any combination of team, position, guaranteed years, amount in millions, number of options, service time, super two status, and agency. The service time filtering allows you to choose one or both boundaries of a range. Service time is denoted as years.days, so 4.148 means four years and 148 days. The player name is hyperlinked to MLBTR's post on the story of the extension.
For example, if you wanted to put Santiago Casilla's recent contract extension in context, it'd be possible to determine if there’s been another multiyear extension worth $10MM or more for a right-handed setup man with five or more years of service time since 2009. As the Tracker shows, Ryan Madson’s 2009 deal with the Phillies resembles the deal Casilla and the Giants just agreed to sign.
The extension tracker can be found under the Tools menu in the navigation bar up top, along with our 2013 Free Agent Tracker, Arbitration Tracker, Non-Tender Tracker, Agency Database and Transaction Tracker.
