The future of the Boston Red Sox was on full display Thursday night as the team’s top three prospects—Roman Anthony, Marcelo Mayer, and Kristian Campbell—delivered a dominant performance in a Spring Breakout showcase against the Tampa Bay Rays. Under the lights at Charlotte Sports Park, the trio made their presence known with a series of home runs, sending a strong message to the rest of Major League Baseball.

The offensive fireworks began in the third inning when Campbell, ranked No. 7 on MLB Pipeline’s top 100 prospects list, smashed a two-run homer to right-center off Rays prospect Trevor Harrison. Moments later, Mayer, the No. 12 prospect in baseball, followed with a solo shot of his own, further igniting the excitement. The final exclamation point came in the fifth inning, when Anthony, the organization’s top-ranked position player, crushed a towering blast beyond the right-field fence, demonstrating the elite power that has made him the No. 1 overall prospect in baseball.

While the home runs were the highlight of the night, the game also showcased Mayer’s defensive skills at shortstop. The 22-year-old fielded a slow roller and made an impressive throw to first, reminding fans why he’s considered the Red Sox’s shortstop of the future.

Red Sox prospects continue to gain momentum in Spring Training

Anthony, Mayer, and Campbell have been the focal point of the Red Sox fan base in recent years, and their performances in the Spring Breakout showcase only reinforced their growing hype. Each player is expected to make their MLB debut at some point in 2025, with Campbell potentially earning a spot on the Opening Day roster as the team’s second baseman.

Mayer, the fourth overall pick in the 2021 MLB Draft, is likely to begin the season at Triple-A Worcester after missing time last year due to injury. However, many believe it won’t take long before he forces his way onto the major league roster. As The Athletic’s Keith Law noted on the 310 To Left podcast, “It might be a month in Triple-A. I can’t tell you exactly how long it’s gonna be, but I don’t think it’s gonna be a full season. By mid-year, he’s banging on the door and they’re trying to find a way to make room for him.”

Anthony, meanwhile, is the youngest of the group at just 20 years old but continues to draw comparisons to elite big-league talent. His powerful left-handed swing has been lauded as one of the best in the minors, and with Wilyer Abreu’s status for Opening Day in question, Anthony could receive an early call-up if the Red Sox need reinforcements in the outfield.

While Spring Training results should always be taken with caution, Thursday’s performance by the Red Sox’s top prospects provided a glimpse of the franchise’s future. The team has invested heavily in its farm system, and Anthony, Mayer, and Campbell represent the next wave of talent poised to make an impact at Fenway Park. If their performance against the Rays was any indication, the Red Sox won’t have to wait much longer before their “Big 3” prospects become major contributors at the highest level.
