Cubs Add Julian Aguiar to Bolster Pitching Depth Ahead of 2027

The Chicago Cubs have officially claimed right-hander Julian Aguiar off waivers from the Cincinnati Reds. While his designation for assignment came as a surprise, Aguiar now has the opportunity to advance his career with a division rival. Chicago will need to make a corresponding roster move, as they currently sit at a full 40-man roster.

A Look at Julian Aguiar’s Journey

Aguiar’s path to this point has been anything but straightforward. Drafted in the 12th round of the 2021 MLB draft, he made his major league debut in 2024. However, his initial foray into the big leagues was rocky; he posted a 6.25 ERA over seven starts spanning 31 2/3 innings. Such struggles are not uncommon for young pitchers, especially those stepping up to face seasoned hitters in the major leagues.

Things took a turn for the worse after an elbow sprain required Tommy John surgery, which typically sidelines players for at least a year. For Aguiar, this meant missing the entirety of the 2025 season. Recovering from this type of surgery is a significant hurdle for any player, not just physically but mentally. The surgery involves a rigorous rehabilitation process, and the pressure to reprise form can be daunting.

When he returned in 2026, the challenges persisted. Complications plagued his recovery, limiting him to just 58 innings in the minors before he made a brief appearance against the Cubs on September 18. In that outing, he allowed two earned runs in three innings during the Reds’ 6-4 victory. It’s a small sample, but reflective of a much larger trend; his performance has not matched the promise reflected at earlier levels.

Performance Analysis and Current Statistics

While Aguiar’s career MLB stats illustrate a figure of a struggling ballplayer—a 6.23 ERA over just 34 2/3 innings—his performance metrics in the minor leagues tell a somewhat different story. He has had more favorable outings in Cincinnati's lower systems, suggesting potential that hasn't yet materialized at the highest level. That said, his transition to Triple-A has been disappointing. Reporting a 5.34 ERA, a 20.88% strikeout rate, and a walk rate of 10.9% across 94 1/3 innings raised red flags regarding his command and effectiveness.

Interestingly, Aguiar’s trials have not been uniform; his struggles are nearly evenly split between pre- and post-surgery performances. Early on, he indicated his ability to perform, which raised expectations. Unfortunately, something hasn't clicked post-recovery, and teams often have to navigate the tricky waters of a player's return from injury with care.

The Cubs' Strategic Acquisition

Aguiar's acquisition, even if he won’t be part of the Cubs’ postseason roster, seems to signal a strategic direction for Chicago's pitching needs. With a full 40-man roster, the Cubs clearly see something in Aguiar that merits the disruption of their current setup. If you're working in this space, you know that teams are increasingly willing to take chances on reclamation projects—players with potential who may have stumbled elsewhere.

This decision likely reflects a broader strategy aimed at collecting pitching talent with an eye toward the future. There’s a possibility he could pitch in the Cubs’ season finale against the Red Sox at Tropicana Field, which would give established pitchers some much-needed rest as the playoffs approach. If the Cubs are positioning themselves for a serious postseason run, managing their pitching staff effectively will be crucial.

Implications for Aguiar and the Chicago Cubs

What this means for Aguiar is significant. The Cubs might see him as a valuable option for their Triple-A rotation, or even as a long-relief candidate in the big leagues. Given Aguiar's track record of starting 87 out of 101 career games, it’s clear that they believe he can still provide some utility, particularly if they can rectify whatever issues have contributed to his lackluster performance.

As for the Cubs, they may be preparing for the uncertain nature of the pitching arms they currently have. Aging veterans, fatigue from a long season, and playoff performance variance all necessitate a deep pitching roster. With Aguiar, they could be looking to cultivate a long-term solution, much like they’ve done with other pitchers who faced early-career struggles.

The true test will be whether Aguiar can regain his footing and deliver on his potential. After all, establishing a solid track record takes time and resilience—qualities that Aguiar must possess in abundance if he wants to find success in Chicago. Here's the thing: his journey is a reminder of how volatile player development can be, especially for pitchers. Only time will tell if the Cubs’ gamble on Aguiar pays off or becomes just another footnote in the fluctuating tale of a promising athlete. Meanwhile, fans will watch closely, hoping for signs that Aguiar is ready to prove his doubters wrong.
