The Cubs will need to make room on their 40-man roster to add outfielder/pinch-runner Terrance Gore. They could take a player off their 40-man roster and risk losing him to waivers, or transfer one of their six players currently on the 10-day DL to the 60-day DL. But all six of those — including closer Brandon Morrow — are expected to join them at some point in September.
