MLB Sets 2027–28 Spring Breakout as Single-Elimination Tournament

The league is positioning the prospect showcase as a flexible spring fixture given a Dec. 1 CBA expiration with a fallback to minor-league–contract players.

Overview

  • Beginning in 2027, the event will shift to late‑March single‑elimination brackets that crown separate Grapefruit and Cactus League champions.
  • For 2026, the format stays as 16 showcase games from March 19–22, with rosters due Thursday and expected headliners including Konnor Griffin, Kevin McGonigle, Leo De Vries, Jesús Made, J.J. Wetherholt and Max Clark.
  • With the collective bargaining agreement set to expire Dec. 1, MLB acknowledges a lockout risk that could delay 40‑man players from reporting to spring training.
  • MLB says the tournament could proceed using players on minor‑league contracts, whose labor deal runs through Dec. 1, 2027, if big‑league roster players are unavailable.
  • The league deferred the tournament launch this spring because of overlap with the World Baseball Classic, noting that a 2022 lockout previously pushed spring exhibitions back to March 17.
