#Cubs Minor moves: Peralta, Johnson
Triple-A Iowa added right-hander Joel Peralta to the roster and activated right-hander Pierce Johnson from the disabled list on Monday. Pitcher Alex Sanabia was released.
A 12-year Major League veteran, Peralta began the season with the Mariners and compiled a 1-0 record and 5.40 ERA in 26 games before he was released on June 4. He signed with the Cubs on June 9.
Johnson, 25, returns from his second stint on the DL. In his first start of the season on April 11, he was hit in the right arm by a line drive. He missed his next start and spent nine days on the disabled list with a right arm contusion. Upon activation, Johnson made three more starts, but then was placed back on the DL with a lat strain on May 5.
