The Minnesota Twins took a calculated risk this offseason when they left outfielder Kala’i Rosario unprotected in the Rule 5 Draft—no teams bit, leaving Rosario to continue his development within the organization. As he enters the 2025 season, the former Midwest League MVP (2023) faces a pivotal campaign that could determine his future with the franchise.
Rosario’s journey has been one of steady progression, but it has also included challenges that have tested his ability to adapt. The 2020 fifth-round pick out of high school in Hawaii has climbed the organizational ladder step by step. His 2023 campaign was his most productive to date, earning him league MVP honors at High-A Cedar Rapids. In 118 games, he hit .252/.364/.467 (.832) with 21 home runs and 27 doubles. He led the league in home runs and RBI while finishing in the top 10 in SLG, OPS, hits, doubles, and walks. It was an impressive campaign for a team that won the league championship.
Rosario looked to build off that campaign, but an elbow injury sidelined him for a significant portion of 2024 at Double-A Wichita. The results were mixed when he was on the field as he hit .235/.321/.405 (.726) with 19 doubles and eight home runs in 67 games. His walk rate dipped from 14.2% in 2023 to 11.4% last season. Unfortunately, his strikeout rate continues to hover around 30%, which is something to watch as he gets more playing time in the upper minors.
For Rosario, the 2025 season is about proving he belongs at the highest levels of the minor leagues and, ultimately, earning a shot at Target Field. A return to Double-A to start the year seems likely, given his limited time there in 2024, but a strong showing could quickly push him to Triple-A St. Paul. The Twins will watch closely to see if he can make the necessary adjustments against upper-level pitching.
One of Rosario’s biggest strengths is his ability to drive the ball with authority. His raw power is legitimate, and if he can tap into it consistently, he could become a 20-25 home run threat in the big leagues. He made a significant mechanical adjustment at the end of 2022, widening his base to quiet his lower half, which allowed him to generate power more efficiently. That change paid dividends in 2023, as he not only hit for power but also improved his plate discipline, cutting down on his chase rate and increasing his walks. His sample size was small in 2024, so it’s hard to decipher if he would have been able to build off those changes.
However, questions remain about his ability to handle more advanced pitching. While he feasts on fastballs, he still struggles with quality-breaking balls. His front hip tends to pull early, making him susceptible to pitches on the outer half. Continuing to refine his approach and improving his ability to adjust mid-swing will be crucial as he faces better arms in 2025.
Defensively, Rosario is limited to a corner outfield spot, but he has a plus arm that has proven to be a weapon. He racked up 14 assists in 2023, demonstrating the ability to cut down runners with strong, accurate throws. His range is fringe-average, but if his bat plays up, he could carve out a role as a power-hitting right fielder at the major league level.
With the Twins boasting a solid group of young outfielders ahead of him, Rosario’s margin for error is shrinking. If he can build on previous success and put together a strong 2025 season, he could position himself for a late-season call-up or, at the very least, a 40-man roster spot heading into 2026. If he struggles, however, he could fall behind in the pecking order, and he might need to hope for an opportunity with another organization.
This year is all about proving he belongs. The power is there, the patience is improving, and the tools are enticing. Now, it’s time for Rosario to show the Twins that he’s more than just a prospect and that he can be a future big leaguer.
