PITTSBURGH -- The Rockies called up right-handed relief pitcher Zach Putnam from Triple-A Colorado Springs on Wednesday for the club's doubleheader with the Pirates.
Under the current collective bargaining agreement, teams are allowed to call up a 26th player for a doubleheader as long as that player is on the 40-man Major League roster. The Rockies will be back to 25 players for Friday's opener of a three-game set with the Mets; they do not have to send Putnam down.
Putnam, 24, acquired from the Indians over the offseason for right-handed pitcher Kevin Slowey, is 1-0 with three saves and a 1.23 ERA at Triple-A Colorado Springs. Putnam has 11 strikeouts to three walks in 7 1/3 innings over five appearances.
Putnam made his Major League debut last season with the Indians, going 1-1 with a 6.14 ERA in eight appearances, with nine strikeouts against no walks.
The doubleheader is necessary because Rockies and Pirates were rained out on Monday.
