Kyle Tucker's left calf soreness forced the Cubs to place him on the 10-day IL retroactive to Saturday, with Moisés Ballesteros recalled to cover. Tucker’s best-case return could come on Sept. 16, leaving 12 games left. He had been surging, batting .400 with a .489 OBP over his last 11 games, including four doubles and four homers, driving 11 RBIs.

The Cubs’ decision reflected a cautious, information-gathering approach as September rosters expand and IL rules allow backdating up to three days. Fantasy managers should monitor Tucker’s progress and Ballesteros’ plate appearances in the interim, as timeline and health will shape rest-of-season value.
