In the latest installment of Moneyline's MLB 30 in '30 series, the focus shifts to predicting the top 30 second basemen for the 2030 season. While projecting future stars at second base can often be challenging due to position shifts, particularly from shortstops, some promising talents have emerged. One notable example is Jackson Holliday, originally drafted as a shortstop, who may transition to second base in the majors as his career progresses.

This evaluation process incorporates both offensive and defensive skill sets, albeit it remains largely subjective, hinging on projections and potential. To preface the rankings, a nod is given to current veterans anticipated to age out of their top performances or transition to different roles before the 2030 season. Players such as Ozzie Albies, Jose Altuve, and Marcus Semien, among others, are expected to be excluded from the top rankings due to age regression.

At the forefront of the rankings is Termarr Johnson of the Pittsburgh Pirates, who, at the age of 26 in 2030, remains an intriguing figure since being selected as the No. 4 overall pick in the 2022 draft. With a celebrated hitting tool, Johnson has yet to fully realize his potential in the minors but possesses a promising future. Following him is Max Muncy of the Las Vegas Athletics, who showed flashes of capability with an impressive OPS in his minor league outings. Other players, including Juan Brito of the Cleveland Guardians and Nico Hoerner of the Chicago Cubs, are also highlighted for their contributions and potential for growth over the next few seasons.
