The future of the Boston Red Sox was on full display as the team’s top three prospects—put on a show in a Spring Breakout matchup against the Tampa Bay Rays. Under the lights at Charlotte Sports Park, the trio made a statement with a series of home runs, showcasing their immense potential to the rest of Major League Baseball.
The offensive surge began in the third inning when Campbell, ranked No. 7 on MLB Pipeline’s Top 100 list, launched a two-run homer to right-center off Rays prospect Trevor Harrison. Moments later, Mayer, baseball’s No. 12 overall prospect, followed with a solo shot, adding to the momentum. The final exclamation mark came in the fifth inning when Anthony, the Red Sox’s top-ranked position player, crushed a towering blast beyond the right-field fence, reinforcing why he holds the title of baseball’s No. 1 overall prospect.
While the home runs stole the spotlight, the game also highlighted Mayer’s defensive prowess at shortstop. The 22-year-old showcased his smooth fielding by charging a slow roller and delivering an impressive throw to first, reaffirming why he’s viewed as the Red Sox’s shortstop of the future.
Red Sox prospects continue to gain momentum in Spring Training
Anthony, Mayer, and Campbell have been at the center of Red Sox fans’ excitement in recent years, and their standout performances in the Spring Breakout showcase only added to the growing anticipation. All three are expected to make their MLB debuts in 2025, with Campbell potentially securing 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 he won’t stay in the minors for long. 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.”
Meanwhile, Anthony, the youngest of the group at just 20 years old, continues to draw comparisons to elite big-league talent. His powerful left-handed swing is considered one of the best in the minors, and with Wilyer Abreu’s Opening Day status uncertain, Anthony could get an early call-up if the Red Sox need outfield reinforcements.

While Spring Training performances should always be taken with caution, Thursday’s showing by the Red Sox’s top prospects offered a glimpse into the franchise’s future. The team has heavily invested in its farm system, and Anthony, Mayer, and Campbell represent the next wave of talent ready to make an impact at Fenway Park. If their performance against the Rays was any indication, Boston’s “Big 3” could soon be making their mark at the highest level.
