A minor league player called up from the EDR will immediately have their eligibility analyzed. All players eligible for multiple positions will be analyzed in the offseason. The rule is 25 GP and 20 IP (half of the eligibility for the MLB clock on prospect contracts) for the past and current season.
Gyorko played 47 games at 2B last year (minors) therefore he should have MI eligibility in addition to CI. This should be reflected in the official roster of the Pirates.
