Chulk, 30, spent last season with the Indians organization, though he only appeared in eight big league games. In 12 innings with the Indians, Chulk allowed five earned runs, walked 10 and struck out four. He went 1-0 with a 2.08 ERA in 18 appearances with Cleveland's Triple-A affiliate.
Chulk has spent parts of the past seven seasons in the Majors, accumulating a 7-15 record and 4.33 ERA in 252 relief appearances.
"He's had success at the Major League level," general manager Neal Huntington said. "He's had success in the National League. Coming back from the ankle injury, our medical people signed off on it and we felt like he would give us a quality competitive option in Spring Training."
Huntington has now signed two relievers to Minor League contracts in the past week, with Wilfredo Ledezma agreeing to terms on a deal last Monday. As Huntington has reiterated this offseason, the Pirates will continue to be aggressive in looking for relief pitching and will particularly pursue pitchers willing to ink Minor League deals and compete for a roster spot in the spring.
