CLEVELAND -- For the second time in two years, the Twins are facing a potential grievance from the players' union over their handling of a starting pitcher.
Last year, the union examined the Twins' handling of Francisco Liriano to see if the team intentionally kept him at Class AAA Rochester to minimize his big league service time. In the end, Liriano's grievance never was filed.
Now, Glen Perkins is considering his own grievance, people familiar with the situation said Saturday.
Perkins has been troubled by shoulder tendinitis and last pitched in Class A. If he is shut down for the season rather than promoted to the majors, it could cost him his chance to qualify for salary arbitration. Most players need three years of big league service time to become arbitration-eligible, but Perkins was on pace to qualify as a "Super-2," a special exception made for players who fall days short of the three-year mark.
The Twins have been frustrated with Perkins over the timing of various medical requests this season, and tensions mounted last week.
Perkins, 26, who had been on the disabled list since Aug. 9 for left shoulder tendinitis, pitched a scoreless inning for Class A Fort Myers and reported no pain.
The Twins activated Perkins from the DL and optioned him to Class AAA Rochester, at which point Perkins asked to see another arm specialist.
Perkins visited Dr. Timothy Kremcheck on Wednesday in Cincinnati and had dye injected into his left shoulder for an enhanced MRI exam. Though Perkins was cleared to pitch, he has to wait a few more days for the dye to clear and likely won't pitch for Rochester.
