According to La Velle E. Neal III of the Minneapolis Star-Tribune, the Twins claimed reliever Juan Morillo off waivers from the Rockies and designated Philip Humber for assignment. They must feel that Morillo has more upside given the mid-90s heat. Both pitchers are out of options. Tracy Ringolsby of Inside The Rockies notes that the Twins were the 21st in line to make the Morillo claim.
Humber, 26, was chosen third overall by the Mets in '04. He was traded to the Twins as part of the Johan Santana deal in February of '08.
