The Moneyline MLB 30 in '30 series takes a forward-looking approach, aiming to predict the top 30 players at each position for the 2030 season. In this installment, the focus shifts to second basemen. The pathway to success at second base often involves shortstop prospects transitioning down the defensive spectrum or being reassigned due to an established major league shortstop. A notable example is Jackson Holliday, who was originally drafted as a shortstop before making the move to second base in the professional ranks.

When evaluating potential players, both offensive and defensive capabilities are considered. This projected ranking, however, remains somewhat subjective, based on potential rather than established performance. Before highlighting the emerging talents expected to dominate the position in 2030, it is essential to acknowledge current veterans projected to retire or transition to other roles by then. Notable players likely to age out of the top rankings include Ozzie Albies (ATL), Jose Altuve (HOU), and Marcus Semien (TEX).

Beginning the countdown at number 30 is Termarr Johnson of the Pittsburgh Pirates, a highly regarded prospect who was drafted fourth overall in 2022. Despite a challenging season, his impressive hit tool continues to promise a bright future as he develops in the minors. Following him is Max Muncy of the Las Vegas Athletics, who began his career slowly but showcased significant potential with a strong Triple-A performance. The list progresses through intriguing talents such as Juan Brito of the Cleveland Guardians and Nico Hoerner of the Chicago Cubs, each bringing unique skills and possibilities to the position as they aspire to make their mark in the coming seasons.
