Chicago Cubs manage roster moves with prospect Owen Ayers and pitcher Javier Assad

The Chicago Cubs are managing roster flexibility and prospect development as the season progresses. Catcher Owen Ayers has emerged as a top prospect, recently rising from High-A to Triple-A Iowa. A 19th-round pick in 2024, Ayers is considered a likely candidate for a September call-up due to his power and defensive versatility, which includes the ability to play first base and the outfield corners.

Meanwhile, pitcher Javier Assad continues to face roster fluctuations. Despite maintaining a 3.46 ERA in 2026 across 22 games, Assad has been frequently moved between the active 26-man roster and Triple-A to accommodate other players and injury returns, such as Daniel Palencia. Assad's ability to pitch in various roles has been a consistent factor for the team, even as he remains subject to being optioned due to having minor league options available.
