To make room for McKenry, 26, on the 40-man roster, the Pirates have designated Wyatt Toregas for assignment. Toregas' stay with the Pirates lasted only four days.
McKenry's Major League experience is limited to six games with the Rockies in 2010. He went 0-for-8 during that stint. McKenry, who was drafted by the Rockies in 2006, was in Colorado's Minor League system while Clint Hurdle was managing the Rockies.
The catcher was dealt from Colorado to Boston on March 29 for pitcher Daniel Turpen and reported to Triple-A Pawtucket. There, the right-handed-hitting catcher hit .274 in 29 games. Behind the plate, McKenry threw out five of 27 baserunners attempting to steal.
The Pirates' need to add a catcher was prompted by recent injuries to Chris Snyder and Ryan Doumit. Snyder will not return for at least two months after having back surgery on Friday. Doumit, who is recovering from an ankle sprain, is expected to be out until at least late July. The Pirates are also without third-string catcher Jason Jaramillo, who is dealing with elbow soreness.
