The Chicago Cubs are activating Ian Happ from the injured list and sending No. 4 prospect Moisés Ballesteros back down to the minor leagues.

The Cubs are activating left fielder Ian Happ off the injured list following a left oblique strain. Moises Ballesteros is expected to be send back to Triple-A Iowa.

To replace Hodge on the 26-man active roster, righthander Ethan Roberts was recalled from Triple-A Iowa. Roberts has a 5.40 ERA (five runs allowed in 8⅓ innings) in nine appearances for the Cubs, though a lot of that high ERA was from his last outing April 26, when he allowed four runs in two innings to the Phillies.
