In the latest edition of Moneyline's 30 in '30 series, a forward-looking analysis is conducted to identify the top 30 players at each position for the 2030 MLB season. The emphasis of this segment lies on second basemen, a position often occupied by players who have transitioned from being shortstops or have adjusted their roles due to the presence of established stars in the infield. Notably, Jackson Holliday, a former shortstop prospect, serves as a relevant example of this trend.

When projecting player success five years into the future, both offensive and defensive capabilities are considered, although the process ultimately involves subjective judgment based on projections. Before analyzing the rankings, it is important to acknowledge several current stars who may likely age out of their prime or transition to different positions by the time the 2030 season arrives. Excluded from these considerations are notable names such as Ozzie Albies of the Atlanta Braves and Jose Altuve of the Houston Astros, both of whom are predicted to step down from their current elite status due to age regression.

As the analysis begins, players like Termarr Johnson of the Pittsburgh Pirates emerge as a key prospect to watch. Drafted fourth overall in 2022, Johnson possesses an impressive 70-grade hit tool but has yet to fully exhibit his potential in the minors. Following him is Max Muncy of the Las Vegas Athletics and Juan Brito from the Cleveland Guardians, both of whom show promising signs of long-term development in their respective organizations. Other players, such as Nico Hoerner, Thomas Saggese, and James Triantos, are also highlighted as individuals with the potential to contribute significantly to their teams by 2030.
