The Cubs are signing outfielder Michael Conforto, according to a report from Jon Heyman of the New York Post. The terms of the deal are not yet known. The Cubs have a full 40-man roster and will need to make a corresponding 40-man move if Conforto is being added on a major league deal, but that can be easily accomplished by transferring right-hander Shelby Miller to the 60-day injured list.

More to come.
