As the anticipation builds for the 2026 MLB season, Baseball America has unveiled its preseason rankings, highlighting the Top 30 prospects for each organization. This early release marks a significant moment in evaluating young talent, focusing on sleeper prospects—players who do not rank within their team’s Top 10 but have the potential to make a notable impact.
In this article, we explore standout sleeper prospects from every MLB team, providing insights into their backgrounds, skills, and predictions for their upcoming seasons.
Arizona Diamondbacks: Ashton Izzi, RHP
Ashton Izzi, a right-handed pitcher acquired by the Arizona Diamondbacks during the 2025 trade deadline, is a name to watch. The 22-year-old, who was a high school draft pick in 2022, has developed a diverse pitching repertoire. His fastball, which can reach the mid-90s, includes a four-seamer with impressive extension and a sinker. Izzi’s introduction of a low-80s sweeper has proved effective, making it his best swing-and-miss pitch last season. With improvements in his strike rate, hitting 66.6% in 2025, he could rise quickly through the ranks in 2026.
Oakland Athletics: Zane Taylor, RHP
Zane Taylor has emerged as a notable prospect for the Oakland Athletics. After being drafted in the fifth round, Taylor showcased his skills in an emergency Triple-A start, striking out four batters in two innings. His fastball, averaging 93.6 mph, has reportedly reached up to 98 mph. With consistent command and the potential for his secondary pitches to develop, Taylor may become a key contributor in the upcoming season.
Atlanta Braves: Conor Essenburg, OF
The Atlanta Braves are highlighting Conor Essenburg, an outfielder with a promising future. After signing for $1.2 million as a fifth-round pick, Essenburg has caught attention with his remarkable bat speed and raw power. Although he has yet to make his official debut, his performance in bridge league action has raised expectations, suggesting he could become a significant hitting prospect if he can translate his power into consistent game performance.
Baltimore Orioles: Anthony Nunez, RHP
The journey of Anthony Nunez to the Baltimore Orioles’ roster has been unconventional. Originally drafted as an infielder, he reinvented himself as a pitcher during his collegiate career. Nunez possesses a formidable fastball that ranges from 95-97 mph, complemented by a hard two-seamer and a variety of effective secondary pitches. His ability to challenge hitters and potential for a high-leverage role in the bullpen makes him a prospect to monitor in 2026.
Boston Red Sox: Henry Godbout, 2B
For the Boston Red Sox, Henry Godbout stands out as a potential breakout candidate. Having shown impressive bat-to-ball skills during his time at Virginia, Godbout has the potential to move quickly through the minors. With the Red Sox’s history of enhancing player performance, there is optimism that he could develop additional power, making him a valuable asset in the infield.
Chicago Cubs: Josiah Hartshorn, OF
The Chicago Cubs’ sleeper prospect is Josiah Hartshorn, a switch-hitter with a blend of power and speed. Despite an injury-plagued high school career, Hartshorn’s athleticism and potential have drawn attention. With an above-average power ceiling and the ability to play multiple outfield positions, he presents an intriguing option for the Cubs if he can maintain his health.
Cincinnati Reds: Jose Franco, RHP
After enduring setbacks due to injury, Jose Franco is making strides with the Cincinnati Reds. His recent performances have showcased improved velocity, reaching up to 97 mph. With his competitive nature and ability to pitch effectively in multiple roles, he could become a valuable contributor to the Reds’ pitching staff in 2026.
Cleveland Guardians: Juneiker Caceres, OF
Juneiker Caceres is a name to watch within the Cleveland Guardians’ system. With an impressive offensive showing in the Dominican Summer League and a solid performance in his stateside debut, Caceres possesses a strong hit and power combination. As he develops, he has the potential to become a key player in the Guardians’ lineup.
Colorado Rockies: Derek Bernard, OF
The Colorado Rockies are optimistic about Derek Bernard, who has consistently performed well since turning pro. With a batting average of .302 in 2025, Bernard has demonstrated power and contact skills, although he will need to improve against tougher pitching. His athleticism and potential for growth make him an exciting prospect heading into 2026.
Chicago White Sox: Matthew Boughton, SS
The Chicago White Sox are looking to Matthew Boughton as a potential asset in the infield. With athleticism and a strong foundation, he has the potential to develop into a valuable player. His speed and defensive capabilities could provide versatility, especially in a team needing depth in the position.
These sleeper prospects represent a mix of untapped potential and intriguing skills across the MLB. As the teams prepare for the 2026 season, these players may emerge as key contributors, reshaping the future of their respective organizations.
