To clear up space for Tonkin, 35, on the 40-man roster, Minnesota designated right-handed pitcher Connor Gillispie, who posted a 14.49 ERA in 13 u2154 innings over four outings with Triple-A St. Paul after the Twins claimed him off waivers from the Miami Marlins on June 23.
The Twins activated Tonkin from the 60-day injured list before selecting his contract. Tonkin, who the Twins claimed off waivers from the New York Yankees last August, originally landed on the 15-day IL with a right shoulder strain on March 26 before being transferred to the 60-day IL on May 16.
