The Phillies reinstated Pop (calf) from the injured list Saturday and designated him for assignment.
Pop landed on the injured list in mid-April after suffering a right calf strain during a spot start. He's been deemed fully healthy after making seven rehab outings in the minors, but his activation will also bring his removal from the 40-man roster since the team needed to clear room for Max Lazar (oblique). The 29-year-old Pop has given up three earned runs over 7.1 innings in the big leagues this season but owns a 9.00 ERA and 2.00 WHIP at Triple-A.
