Cubs Starting Pitching options Cade Horton injury recap

Horton exited his second start of 2026 in the second inning. He experienced discomfort that began in his wrist and moved into his forearm. The diagnosis was a right forearm strain, with further imaging and evaluation pending in Chicago. The clarity seems to be in, and season-ending surgery is on the table.

Chicago Cubs Starting Pitching Options: Internal Replacements

The Cubs’ rotation depth is already under strain. Horton and Matthew Boyd are on the IL. Justin Steele and Jordan Wicks are also unavailable. The team is leaning heavily on its next layer.

Colin Rea and Javier Assad are the most immediate Cubs pitching replacements, both already positioned to absorb starts. Ben Brown offers a higher-upside alternative but profiles more as a flexible, multi-inning arm than a locked-in starter.

Further down, Jaxon Wiggins remains the most intriguing Triple-A option, though the organization appears hesitant to accelerate his timeline. Riley Martin fills a roster spot but is not viewed as a rotation answer.

Chicago Cubs Starting Pitching Options: External Replacements

Externally, the conversation is already shifting toward veteran help. With not much left on the market, free agent Lucas Giolito is a realistic short-term stabilizer. Giolito’s 2025 production—3.41 ERA over 145 innings—fits the Cubs’ current need for innings and reliability. He does not have draft compensation attached. This lack of attachment represents a cleaner acquisition path compared to trade targets. This is especially true if the front office wants to avoid moving additional prospects after already trading for Edward Cabrera.

Still, the broader expectation is that any major upgrade likely comes via trade.

Final take

Short term, the Cubs will patch this with Rea and Assad—that’s the practical, low-disruption move. But the bigger picture is harder to ignore. This rotation was already walking a tightrope. Horton’s injury may have simply revealed it earlier than expected. Any thoughts of making a trade right this minute seem a bit far-fetched. It’s too early in the season, but perhaps Zac Gallen could be revisited??

So the immediate sign Giolito right now. There is talent in the minors. Matt Shaw seems replaceable. A guy like James Triantos or a few other prospects might be blocked by the locked-up infield.
