Chicago Cubs 2026 Top 20 Prospects, No. 1: Moisés Ballesteros

[RandallPnkFloyd]

 

Having spent the last couple of weeks examining the top 20 prospects in the Chicago Cubs organization (as voted on by our North Side Baseball writers), we, at last turn our attention to the man in the top spot who may lack a position but not a future in Chicago.

#1 - Moisés Ballesteros (Iowa Cubs, Triple-A)
A relatively quick riser throughout the Cubs' system after being signed out of Venezuela in 2021, the 2025 campaign was Ballesteros' first extended action in Triple-A. The year prior, he split between Double-A & Iowa, with his first taste of the higher level leading to an uptick in strikeouts, a dip in walks, and a fall in his wRC+ to exactly average (100). An adjustment manifested quickly, however. 

Last year, Ballesteros was back in Iowa to start the year. Across more than 500 plate appearances, he slashed .316/.385/.473, with a 13.2 percent strikeout rate that was eight points lower than when he initially reached that level. The walk rate crept back up (9.6 percent), and his total body of work featured a wRC+ that came in at 121. One might have hoped for a bit more in the power game (.157 ISO), but the bat-to-ball skills were on display enough that Ballesteros was able to earn a cup of coffee with the Cubs. In 20 games, he finished at a 143 wRC+ and showcased some particularly encouraging signs toward what his future could look like in the lineup. 

What To Like
The bat is big-league ready. Ballesteros has already proven that much, both through the evidence in Iowa and his small body of work at Wrigley Field: 

Ballesteros made contact at an 81.8 percent rate in Iowa last year and didn't experience too much of a downturn upon his call-up (77.6 percent). In addition to quality contact skills, he's plenty capable of driving it to all fields; he split between a 35.6 percent pull rate and a 33.4 percent oppo rate in Iowa last year.

What's more is that his swing is adaptable. Matt Trueblood recently explored this as a benefit within Ballesteros' game. Not only is he capable of creating consistent contact, but he's able to generate different types of it based on pitch type. While it'll continue to evolve, that's part of the reason we see such a wide distribution to each portion of the field. When that component is considered in conjunction with the overall ability to make contact, it's a really enticing bat for an organization that likes efficiency in their swings. 

However, there's just a bit more nuance needed within that offensive profile before we're ready to declare Moisés Ballesteros an everyday bat for the 2026 Cubs.

What To Work On
From an offensive standpoint, Ballesteros has work to do on two fronts. The first is adjusting the approach to suit his skill set. Yes, he can create contact from various parts of the zone and spin that into hits in any part of the field. But he could also be seizing more opportunities to create impactful contact: 

There's just a touch too much aggression in Ballesteros' approach at present. He's able to compensate well given the aforementioned bat-to-ball skills and inherent ability to avoid whiffs, but he's also not finding the barrel at the type of rate one might expect, and there's room for growth in his overall hard hit rate. 

Further, there's a bit more elevation needed if Ballesteros is to get his game moving to the next level. He spent 49.6 percent of the time on the ground with his contact last year and was up over 62 percent in his small sample with the major-league club. While the all-fields contact offers its share of benefits, the nature of such an adaptable swing should allow him to lean into the pull side just a bit more. If Ballesteros' ability to recognize pitches continues to develop, that varying swing path should be able to produce such results to a degree that will allow him to reap the benefits of an increased barrel and hard hit rate. 

On the defensive side, the picture has been murky for quite some time. The Cubs are continuing to develop Ballesteros as a catcher, despite the fact that he appeared there just once in his 20 major-league games last season. His arm is decent from behind the plate, but he has enough work to do in virtually every facet that any answers about his long-term position might have to wait until the end of 2026, at the soonest. Nevertheless, the contact skills being what they are could help him to regular work as a designated hitter, and demonstration of the refinement needed could make a defensive position for a bat like that somewhat superfluous. 

What's Next
There are two paths before Moisés Ballesteros ahead of 2026. 

The first is that Seiya Suzuki slides back into regular work in right field following Kyle Tucker's departure, freeing up the designated hitter role for Ballesteros. Perhaps he gets occasional work behind the plate but comes into a lineup on the strength of his bat almost exclusively. Maybe he draws an occasional start or appearance at first base, but that part seems less likely for a player standing 5'8". That's assuming the bat continues as it is, with the adjustments to the approach manifesting into something that makes keeping him entrenched in a spot Craig Counsell might've preferred to rotate justified. 

Of course, the possibility exists that the team goes in a different direction, wherein Ballesteros gets just a bit more seasoning in Triple-A, especially to work on his defensive game. With Carson Kelly reaching free agency following the year, the Cubs will have some space behind the dish. Extra time to develop the glove and all of the intricacies that come with being a big-league catcher could do Ballesteros some good. Injuries could land him back up on the Cubs' roster at a decent rate, but the focus remains on development in this case.

In terms of a one-or-the-other scenario, the former feels far more likely. The Cubs could certainly work with Ballesteros at the top level throughout the year, even if it features fewer game reps. They could go that route while keeping one of the organization's best bats in tow for the long-term. With a decent volume of bench options remaining in camp, though, it might not be entirely unreasonable to see them go the latter path, either. 

Either way, though, we're likely to see a whole bunch of the hitting artist known as Mo Baller throughout the 2026 season.
