Jaxon Wiggins may have just made the Chicago Cubs’ September decision much easier. After moving from the starting rotation to the bullpen at Triple-A Iowa, the young pitching prospect has suddenly shown the kind of dominance that could force the Cubs to give him a look at the major-league level.
The Cubs originally viewed Wiggins as a potential starting pitcher for the future, but the temporary move to relief appears to be unlocking another side of his game. The 24-year-old has looked more aggressive and effective in shorter outings, giving the organization valuable information as it considers how to manage his development during the final stretch of the 2026 season.
Wiggins’ transition to the bullpen was first put on display during the Minor League Field of Dreams game, and it quickly became clear that the experiment was more than a one-time adjustment. Rather than returning to a starting role, he has remained in relief for Iowa and has continued to produce impressive results.
Across his first three appearances as a reliever, Wiggins has thrown three scoreless innings, striking out five of the 12 batters he has faced. Even more encouraging, he has surrendered no hits during the transition. Although three walks show there is still room for improvement with his command, the overall performance suggests that his power and stuff could play extremely well in a bullpen role.
Wiggins’ bullpen move could change his Cubs future
The biggest question now isn’t whether Wiggins can dominate in short outings it is whether he can demonstrate the durability and consistency necessary to become a legitimate September or postseason option.
One concern is his workload pattern. Wiggins has not yet appeared on consecutive days, with several days separating each of his first three relief outings. That could become important if the Cubs are considering him for an October bullpen, where relievers are often expected to be available frequently and sometimes pitch on back-to-back days.
Still, the Cubs have plenty of reasons to keep watching closely. A strong finish in Iowa could convince the organization that Wiggins deserves a chance to experience the major leagues, even if his eventual future remains in the starting rotation.
There is also a roster-management issue that makes the situation more urgent. Wiggins is eligible for the Rule 5 Draft this offseason, meaning Chicago cannot simply leave him unprotected indefinitely. The Cubs will need to add him to their 40-man roster before the December deadline if they want to ensure he remains in the organization.
That makes September particularly important.
If Wiggins continues overpowering hitters out of Iowa’s bullpen, the Cubs could have a straightforward decision on their hands: protect him, bring him to Chicago and see whether his new relief role can provide an unexpected weapon for the stretch run.
What began as an experiment to manage his innings may now be turning into something much bigger. Wiggins is no longer simply a prospect the Cubs are developing for the future his recent dominance is giving the organization a reason to start thinking about what he can contribute right now.
