Moneyline presents the MLB 30 in '30 series, which aims to forecast the best players at each position for the 2030 season. This installment focuses on second basemen. Predicting the future of this position can be challenging, as many current second basemen are former shortstop prospects who have transitioned due to changing roles within their teams. For instance, Jackson Holliday, initially drafted and developed as a shortstop, now occupies the second base position in the major leagues. Both offensive and defensive tools were considered in evaluating players' potential over the next five years, though this assessment remains largely subjective.

As the rankings commence, it's important to recognize some established players expected to either age out of their prime or transition to different positions by 2030. Notable veterans omitted from these rankings include Atlanta Braves' Ozzie Albies, Houston Astros' Jose Altuve, and New York Mets' Jeff McNeil, among others, due to anticipated age regression.

The countdown begins with the projected 30 best second basemen for 2030. At number 30, Termarr Johnson of the Pittsburgh Pirates, who at 26 years old, was a highly regarded prospect drafted 4th overall in 2022. Despite an underwhelming minor league performance thus far, expectations remain high for this 20-year-old infielder, who displayed a strong walk rate in his last season. Following closely at number 29 is Max Muncy from the Las Vegas Athletics, who, after a slow start, showed signs of promise with an impressive OPS in Triple-A last season. Acquired by the Cleveland Guardians, Juan Brito ranks 28th after a successful Triple-A campaign, while number 27, Nico Hoerner of the Chicago Cubs, showcases elite defensive skills despite an average offensive output.

Thomas Saggese of the St. Louis Cardinals finds himself at number 26, recognized after his acquisition and solid offensive performance in Triple-A. At number 25 is James Triantos from the Chicago Cubs, a young prospect with a strong bat, followed by Nick Gonzales of the Pirates at number 24, who made his major league debut last year. Significant mention goes to Luisangel Acuña, now with the New York Mets, ranking 23rd after his successful stint with the Rangers, and number 22, Luke Keaschall of the Minnesota Twins, demonstrating offensive prowess since his draft.

Further in the rankings, Andrés Giménez from the Toronto Blue Jays stands at number 21, known for his defensive accolades. The Arizona Diamondbacks' Demetrio Crisantes, at number 20, shows promise after a strong debut season, while Felnin Celesten from the Seattle Mariners is at 19, recognized for his potential amidst a crowded infield. The Washington Nationals' Luis García Jr., positioned at 18, finally delivered a breakout season, making the case for his solidified role. Bryson Stott of the Philadelphia Phillies ranks 17th, having adapted to a new position with varied statistics.

Sal Stewart from the Cincinnati Reds occupies the 16th spot, showcasing impressive minor league stats. At number 15 is Hyeseong Kim of the Los Angeles Dodgers, who after a successful stint in the KBO, is making significant strides in the majors. Brooks Lee from the Minnesota Twins follows at 14, known for his versatility across positions. Gleyber Torres, recently with the Detroit Tigers, maintains relevance at number 13, while Gavin Kilen from the University of Tennessee is a promising prospect for the upcoming 2025 draft, ranking 12th.

Matt McLain of the Cincinnati Reds ranks 11th following a productive rookie season, despite facing setbacks due to injury. Bo Bichette, who has struggled defensively but shown offensive resilience, is at number 10. The Seattle Mariners' Michael Arroyo, a dual threat at the plate, ranks 9th. Jazz Chisholm Jr. of the New York Yankees stands 8th, touted for his power and speed if he can stay healthy. Brice Turang from the Milwaukee Brewers ranks 7th after exemplary defensive performances and base-running abilities.

Number 6 is Kevin McGonigle, a notable young talent showcasing vibrant hitting skills. At number 5 is Christian Moore from the University of Tennessee, who could break into the majors soon based on his college achievements. JJ Wetherholt, who slipped to the 7th overall pick in the draft due to injuries, ranks 4th with immense potential for future stardom. Travis Bazzana, selected first overall in 2024, comes in at number 3, showing elite hitting capabilities and potential as a cornerstone player.

The 2nd position is held by Jackson Holliday, who started as the consensus top prospect, aiming for a turnaround after an initial rocky start in the majors. Last but not least, Kristian Campbell from the Boston Red Sox tops the list at number 1 following an outstanding minor league season. Campbell’s versatility and skill set project him as a potential All-Star and foundational player for the Red Sox in the coming years.
