Cubs place Ian Happ on IL, recall Moises Ballesteros from Iowa

Chicago Cubs outfielder Ian Happ is headed to the injured list, and slugging prospect Moises Ballesteros is headed to the big leagues.

In a corresponding roster move, the Cubs transferred pitcher Tyson Miller to the 60-day injured list to make room on the 40-man roster for Ballesteros.

Happ, who had missed the team’s last three games with an oblique injury, will now head to the 10-day injured list, with manager Craig Counsell telling reporters that he hoped Happ would be back sooner rather than later.

In 39 games this season Happ has slashed .269/.364/.381 with three home runs and 19 RBI’s, primarily serving as the team’s lead-off hitter.

The move was made retroactively to May 10, meaning Happ can return after the team’s current homestand.

Ballesteros, a top-100 prospect in baseball and the Cubs’ No. 4-ranked prospect according to MLB Pipeline, has been terrorizing minor league pitching in Iowa this season. He has already slugged four home runs and is slashing an impressive .368/.420/.522, and he has racked up 12 extra-base hits in 34 games.

Miller has been dealing with a hip impingement, and suffered setbacks during his rehab assignment in Iowa, according to Maddie Lee of the Chicago Sun-Times.
