MLB Roster Rule May Block Woodruff’s World Series Return

A technicality in Major League Baseball’s postseason roster regulations has emerged as the primary obstacle preventing the Milwaukee Brewers from adding Brandon Woodruff to their World Series roster, according to club officials briefed on the situation.

The issue is not medical. It is procedural.

Under MLB rules, a team can only replace an injured player during the postseason if the ailment is acute and non-chronic. The Brewers have contacted the league office seeking clarification on how that rule would apply if they activate Woodruff and he suffers another shoulder problem, The Athletic’s Ken Rosenthal reported Tuesday. Officials who spoke on the condition of anonymity because no decision has been made expressed concern that any setback could be classified as a recurrence of his pre-existing injury, leaving Milwaukee permanently short-handed in the bullpen.

That classification would lock the team into playing with 12 pitchers for the remainder of the series.

Woodruff, a two-time All-Star and the longest-tenured player on the Brewers’ roster, was initially expected to miss the entire season due to a shoulder injury that nearly required surgery. Just before the procedure was scheduled, imaging showed unexpected healing, according to the Milwaukee Journal Sentinel. He began a throwing progression and completed a 31-pitch bullpen session at Dodger Stadium last week. Facing live hitters was scheduled for Tuesday.

“It’s gonna be hard to keep me off that roster,” Woodruff told the Journal Sentinel’s Curt Hogg during the team’s celebration after Game 4 of the National League Championship Series.

Finding a roster spot is mathematically simple. MLB allows 13 pitchers on a postseason roster, and Milwaukee has not used two of the arms carried through the NLCS. Activating Woodruff requires dropping a pitcher who hasn’t appeared in a game.

The physical limitations present a separate calculation. Medical staff must determine whether Woodruff can handle multiple warm-up cycles in a single game or if his usage would be restricted to one-inning appearances. A reliever limited to a single inning offers minimal tactical flexibility in a seven-game series where bullpen management dictates outcomes.

MLB introduced stricter injury replacement protocols following years of teams exploiting loopholes to swap healthy players between series. The current framework requires teams to submit medical documentation to the commissioner’s office, which then determines eligibility for replacement. A player ruled ineligible for substitution remains on the active roster but cannot pitch, effectively burning a spot for the rest of the round.

The Brewers advanced to the World Series after winning Game 4 of the NLCS. No timeline has been announced for when the league will provide its ruling on the roster interpretation.
