Hayden Cantrelle’s ninth-inning grand slam flips a 7-6 Las Vegas lead into a 10-7 Iowa win, signaling late-season power from Cubs prospects. Pérez, Long, Ballesteros and Alcántara contribute multi-hit days as the Iowa attack paces the system. Smokies and South Bend stumble in tight ones, while Myrtle Beach stays competitive. The Cubs’ farm continues to showcase depth and potential call-ups as the season winds down, a boon for dynasty and keeper fantasy managers.
