Major League Baseball teams usually sign two- or four-year deals called Player Development Contracts (PDC) with minor league teams. Contracts can only be up for renewal in even numbered years.
Twelve of the 16 teams in the Pacific Coast League, including Oklahoma City, have contracts expiring next September (2014).
Four teams signed through 2016 include: Omaha (Kansas City); Iowa (Chicago Cubs) and Reno (Arizona). Round Rock has five years left on a deal with the Texas Rangers that runs through 2018.
Most expiring contracts are rubber-stamp deals where both sides re-up for another two or four years. But on occasion there is movement, as RedHawks fans experienced when the Rangers moved their Triple-A team to Round Rock three years ago after a 28-year run in Oklahoma City.
Major league officials and minor league teams are prohibited from discussing future deals. A 10-day window in mid-September in even-numbered years is when expiring deals officially are discussed.
