Overview

• Ian Happ has been placed on the 10-day injured list with an oblique strain, creating an opportunity for roster adjustments.
• The Cubs have called up Moises Ballesteros, their fourth-ranked prospect, from Triple-A Iowa to bolster the lineup.
• Ballesteros has excelled offensively this season, posting a .942 OPS, a .368 batting average, and a 19-game hitting streak in Triple-A.
• Adding Ballesteros to the 40-man roster will require a move, likely designating Justin Turner or Vidal Brujan for assignment.
• Defensive questions remain about Ballesteros's ability to handle catching duties at the major league level.
