MLB Roster Expansion: Top Prospects to Watch in September (2026)

The MLB roster expansions are an exciting time for baseball fans, offering a glimpse into the future stars of the game. With the addition of two players to each team's active roster, let's delve into some of the standout prospects and their potential impact on the final month of the season. Here's my take on the players to watch and the narratives that make them intriguing:

The Young Sluggers

  • Lazaro Montes, Mariners: Montes, an outfielder, made a splash in his debut, showcasing power with a solo homer and an RBI single. What's remarkable is that this young talent has already hit 39 home runs this season, indicating a bright future. However, as I've analyzed in my video, contact consistency is a concern. The Mariners will be keen to address this issue, but for now, Montes's power-hitting potential is a thrilling addition to the lineup.

  • Ethan Salas, Padres: Salas, a catcher, is set to become the youngest player to start at catcher since the legendary Pudge Rodriguez. His batting stats are impressive, and his ability to control the strike zone at such a young age is a rare talent. The Padres plan to utilize him in various roles, and his left-handed hitting could earn him a regular spot in the lineup. I believe Salas has the skills to make an immediate impact and could be a key player in the Padres' strategy for the coming weeks.

  • Leo Bernal, Cardinals: Bernal, a highly-ranked prospect, is a switch-hitter with solid power. His batting stats in Triple-A are promising, but his contact rate is a potential area of improvement. The Cardinals seem to be giving him a chance to compete for the second catcher spot, and his performance against left-handed starters could be a deciding factor. In my view, Bernal's development will be crucial for the Cardinals' long-term success.

Infield Surprises

  • Yohandy Morales, Nationals: Morales, a former high draft pick, has been a standout performer in Triple-A, with impressive power numbers. His injury earlier this season may have delayed his MLB debut, but he's now getting his chance. The Nationals are utilizing him at first base and designated hitter, and his performance against the Braves suggests he could be a fantasy asset. Personally, I believe Morales has the potential to be a long-term solution for the Nationals at first base.

  • Adael Amador, Rockies: Amador, a middle infielder, is getting another shot at the big leagues. His previous stints were underwhelming, but he's shown improvements in making contact and reducing ground balls. The Rockies' new management might favor his consistent contact approach. I predict a potential battle for playing time with Ezequiel Tovar, which could be an intriguing storyline to follow.

Pitching Prospects

  • Ricky Tiedemann, Blue Jays: Tiedemann, a former top prospect, has battled injuries but is now back on the mound. His fastball velocity remains impressive, and the addition of a harder slider could be a game-changer. While he'll be a reliever this season, I foresee a potential rotation spot next year if he finishes the season strong. The Blue Jays' pitching staff could be significantly bolstered by his presence.

  • Jedixson Paez, Red Sox: Paez, despite a promising minor league record, struggled in his MLB debut. His fastball command needs refinement, but his off-speed pitches show promise. The Red Sox might give him another opportunity to start, but his impact this season may be limited. In my opinion, Paez's development is a long-term investment for the Red Sox, and his future role could be crucial in maintaining their pitching depth.

These roster expansions provide a fascinating glimpse into the future of MLB. While some players will make immediate impacts, others will be projects for the future. Personally, I find this period of the season captivating, as it showcases the raw talent and potential that will shape the league in the years to come. The narratives surrounding these players are what make baseball such a compelling sport, and I can't wait to see how these prospects develop and contribute to their teams' success.
