MLB’s Spring Breakout returns March 19, with a prospect tournament planned for 2027

For four days in March, the most closely watched players in Major League Baseball won’t be on 40-man rosters.

Beginning March 19, all 30 clubs will send their top minor leaguers onto spring training fields in Arizona and Florida for the third edition of Spring Breakout, a 16-game prospect showcase that has rapidly grown from an experiment into a permanent fixture on MLB’s calendar.

A four-day prospect slate

The 2026 event, which runs through March 22, will again match club against club in prospects-only exhibitions. At the same time, the league is using it as a bridge to a larger overhaul: a formal single-elimination “Spring Breakout Tournament” planned for 2027 in both the Cactus and Grapefruit leagues.

In a March 2 announcement detailing the expansion, Commissioner Rob Manfred called Spring Breakout “invaluable exposure to the future stars of our game” and said the coming tournament format would “take this event to the next level and create a unique experience for our fans ahead of Opening Day.”

The 2026 schedule keeps the showcase format that debuted two years ago. Six games are set for opening day on March 19, with 10 more spread over the next three days. Some are stand-alone events in spring facilities; others are scheduled as single-admission doubleheaders, with a standard spring training game followed by a prospects contest about a half-hour later.

Every team will designate a pool of roughly 35 to 40 minor leaguers for Spring Breakout, heavily weighted toward each organization’s highest-ranked prospects. From there, clubs will set game-day lineups and pitching plans much as they do for spring exhibitions.

Who’s playing: Top-100 prospects, including the top five

MLB says more than half of the players on its MLB Pipeline Top 100 Prospects list are expected to participate this year, including the consensus top five. That group is headlined by Pittsburgh Pirates infielder Konnor Griffin (No. 1 overall) and Detroit Tigers infielder Kevin McGonigle (No. 2). The two are scheduled to face off when Pirates and Tigers prospects meet during the four-day slate.

Also ticketed for Spring Breakout are shortstops Jesús Made of the Milwaukee Brewers (No. 3), Leo De Vries of the Oakland Athletics (No. 4) and JJ Wetherholt of the St. Louis Cardinals (No. 5), along with other highly regarded names such as Tigers outfielder Max Clark, Padres catcher Ethan Salas, Twins outfielder Walker Jenkins and Rockies infielder Ethan Holliday.

Spring Breakout games are distinct from standard split-squad spring training contests. Rosters are limited to prospects and recent minor league signees; established major league regulars do not participate. Clubs retain control over how heavily they use any individual player, particularly young pitchers, but the league markets the games as a unified event rather than as back-field scrimmages.

Streaming and TV: Free, live, and unblacked-out

The four days are also becoming a major content play. MLB will stream all 16 games live and free on MLB.TV, MLB.com and the MLB app, with no blackout restrictions.

The league-owned MLB Network plans to carry eight games live and will unveil team rosters in a one-hour special on March 5 featuring Matt Vasgersian, Harold Reynolds and MLB Pipeline analyst Jim Callis.

Several regional sports networks will fold Spring Breakout into their spring schedules, including team-controlled channels in markets such as Houston, Dallas–Fort Worth and San Francisco. In addition, multiple games will air on the Amazon-backed MLB FAST Channel, a free ad-supported streaming outlet that has become a regular partner for league programming.

A March runway from WBC to Opening Day

Spring Breakout slots directly behind the World Baseball Classic on baseball’s March calendar. The 2026 WBC is scheduled to conclude just days before the prospect showcase, creating an uninterrupted run from international stars to future major leaguers to Opening Day.

What changes in 2027

While this year’s edition remains an exhibition slate, the league’s announcement outlines a significant change starting in 2027. In that year, Spring Breakout will shift to a tournament format in each spring training region. Top-prospect squads from the 15 Grapefruit League clubs in Florida and the 15 Cactus League clubs in Arizona will play single-elimination brackets until each side crowns a champion.

MLB said it chose 2027 for the shift in order to avoid colliding with the 2026 WBC, which already compresses spring training schedules.

A fast-growing track record — and lingering questions

The prospect showcase has quickly built a track record. According to league figures, 210 players who appeared in Spring Breakout games in 2024 and 2025 have already reached the majors. That group includes three of the last four winners of the Rookie of the Year Award — right-hander Paul Skenes and first basemen Nick Kurtz and Drake Baldwin — along with several recent All-Stars such as outfielders James Wood and Jackson Chourio and right-hander Jacob Misiorowski.

For clubs, the event doubles as a development tool and a marketing platform. Many of the players involved have already appeared for their parent club’s minor league affiliates, and some organizations have leaned on that connection in local promotions. The Brooklyn Cyclones, for example, recently highlighted that more than two dozen of their former players were listed in the New York Mets’ Spring Breakout pool.

“Spring Breakout has already shown that these games are often a first look at players who will be making an impact at the Major League level in the near future,” Manfred said in the March 2 statement. “Fans will have the opportunity to see many of our game’s top young talents on the same field before they reach the big leagues.”

The format also gives front offices a chance to evaluate prospects in an environment that more closely resembles a major league setting, with television crews, advanced scouting and larger crowds than typical back-field games, without starting their service-time clocks.

At the same time, the growing visibility and the coming tournament structure raise questions that have not yet surfaced publicly in labor talks. Spring Breakout features players who, for the most part, are not yet members of the Major League Baseball Players Association and are paid under minor league contracts. As the event gains sponsors, ratings and competitive intensity, agents and player representatives could eventually push for clearer guidelines around workload, injury protections and compensation tied to participation.

For now, the league is emphasizing access. By making all games available at no cost on its digital platforms and layering coverage across cable and free streaming, MLB is using the showcase to introduce casual fans to prospects they may otherwise only know from rankings and box scores.

Key dates and marquee matchups

Spring Breakout begins March 19 with six games, including a night matchup between New York Mets and Tampa Bay Rays prospects in Port St. Lucie, Florida. The schedule closes March 22 in Mesa, Arizona, where Brewers prospects will face Athletics prospects at Hohokam Stadium.

If the first two editions are any indication, many of the players on those fields will be back on television soon in different uniforms and bigger stadiums. With a tournament on the horizon and a growing list of alumni in big league clubhouses, Spring Breakout is positioned to remain a regular checkpoint on the way there.
