The Cubs promote Owen Caissie from Triple-A Iowa as Miguel Amaya lands on the 10-day IL with a left ankle sprain, reopening the catching rotation in Chicago. Caissie, a 23-year-old Ontario native, debuted in Toronto amid home-country buzz, delivering a pro-level approach and teased power after a standout Iowa season (22 homers, 52 RBIs in 93 games). The club stresses pace and rest as Caissie integrates, signaling a flexible path rather than an immediate full-time role. Amaya’s injury history adds urgency to Caissie’s acclimation, and the Cubs will monitor how rest days shape the lineup. Caissie’s strong August in the minors hints at a tempting long-term upside if he sticks. The Canadian debut angle fuels excitement, tying into a larger roster shuffle sparked by trades and in-season adjustments.
