The Chicago Cubs are on a promising path as they build a formidable farm system, especially following the trade deadline sales of their 2016 World Series team in 2021. This article profiles the top fantasy baseball prospects for the Cubs who may make an impact by 2026. Among them are notable names such as Jaxon Wiggins, Owen Caissie, and Kevin Alcantara, alongside recent draft additions like Cade Horton and Matt Shaw. With the anticipated graduation of several top-100 prospects this season, the Cubs still have promising talent on the horizon.
Top Fantasy Baseball Prospects for 2026 Chicago Cubs
1. Jaxon Wiggins – Starting Pitcher
- Age: 21
- MiLB Stats: 78.0 IP, 2.19 ERA, 31% K rate, 11.5% BB rate
Jaxon Wiggins has emerged as a leading pitching prospect. Drafted in the second round in 2023, he boasts an upper-90s fastball rated at a 70-grade by Fangraphs. Wiggins’s performance indicates he could soon occupy a top rotation spot in Chicago, especially with current pitching depth concerns.
2. Owen Caissie – Outfielder
- Age: 23
- MiLB Stats: .286 AVG, .386 OBP, 22 HR
- MLB Stats: .192 AVG, 1 HR
Owen Caissie’s major league statistics may not reflect his potential. Limited playing time hindered his MLB success, while his Triple-A performance showcased his elite power potential. Despite concerns about strikeouts, he remains a vital long-term asset for the Cubs, with expectations of 30+ home runs in the near future.
3. Ethan Conrad – Outfielder
- Age: 22
- Drafted: 2025
After a strong collegiate career, Ethan Conrad was drafted 17th overall in 2025. He is projected to begin in High-A in 2026. His left-handed swing and impressive statistics demonstrate that he could flourish in the Cubs’ system.
4. Moisés Ballesteros – Designated Hitter
- Age: 22
- MiLB Stats: .316 AVG, 13 HR
- MLB Stats: .298 AVG, 2 HR
Moisés Ballesteros has shown impressive hitting ability across various levels. As he potentially assumes the DH role in 2026, maintaining his late-season momentum will be crucial to maximizing his fantasy value.
5. Jefferson Rojas – Infielder
- Age: 20
- MiLB Stats: .236 AVG, 11 HR, 19 SB
Jefferson Rojas showcases a refined swing and significant speed. His capacity for improvement and potential to steal bases adds enticing upside as he develops within the organization.
6. Kevin Alcantara – Outfielder
- Age: 23
- MiLB Stats: .266 AVG, 17 HR
Kevin Alcantara is recovering from offseason surgery but remains a key outfield prospect. His power potential is evident, but he needs to refine his swing to make a more considerable impact in 2026.
7. Josiah Hartshorn – Outfielder
- Age: 18
- Drafted: 2025
The Cubs invested significantly in Josiah Hartshorn, showcasing their belief in his power potential. Although he hasn’t played professionally yet, his switch-hitting ability and impressive physicality hint at a bright future.
