Can an MLB starting pitcher keep batting as the DH after being replaced on the mound?
Yes. When a starting pitcher is listed on the initial lineup card as both pitcher and designated hitter, the rules treat those as separate roles. If the player is replaced as pitcher, the player may remain in the DH batting slot but cannot pitch again in that game. If replaced as DH, the player may continue pitching but cannot keep batting for himself. The special two-way setup is available only through the initial lineup card; a substitute cannot inherit both roles as separate people. Under Rule 5.11(b), the original dual-role player batting or running as DH, or assuming the pitcher role from DH, does not by itself end the team's DH role. That exception does not restore pitching rights after replacement as pitcher. Moving that player from pitcher or DH to a defensive position other than pitcher ends the team's DH role.

The initial card lists the player twice
The starting-pitcher-as-DH provision treats the player as two separate people for lineup purposes. The initial card lists ten players and names that starter twice: once in the pitcher role and once in the DH role. This is a specific starting lineup option, not a general right for any player to switch roles later.
Replacing the pitcher can leave the DH slot intact
If a reliever replaces the starting pitcher, the starter can remain in the batting order as the designated hitter. The removed pitcher cannot return to pitch later in the game. In the opposite direction, if the player is replaced as DH, that player can continue as pitcher but can no longer hit for himself.
The role split has limits
The special initial lineup treatment cannot be passed to a substitute who is newly installed as both separate roles after both original roles are replaced. The initial card is the one time the club may identify the starting pitcher as batting for himself under this provision.
Rule 5.11(b) overrides the relevant general DH termination conditions for this original dual-role player. Batting or running as DH, or assuming the pitcher role from DH, does not by itself end the club's DH role. A move from pitcher or DH to a defensive position other than pitcher does end that role for the rest of the game. This exception does not let a player already replaced as pitcher pitch again.
Which rulebook this explanation uses
This guide follows the Office of the Commissioner of Baseball's Official Baseball Rules, 2026 Edition. The amendment summary does not list Rule 5.11(b) as a 2026 change and is not a historical redline. The book states MLB and affiliated professional-development scope and gives no separate day-level effective date.
One player, two named roles
In a fictional opening lineup, Devon is listed twice, as starting pitcher and DH. When a reliever takes the mound, Devon stays in the DH batting slot but may not pitch again. In a separate branch, Devon's DH role is replaced while Devon remains the pitcher; Devon may keep pitching but cannot bat for himself. A new two-way substitute cannot be inserted to inherit both roles as separate lineup people. The original dual-role player batting or running as DH, or assuming the pitcher role from DH while still permitted to pitch, does not by itself end the team's DH role. If Devon instead moves from the mound or DH role to a defensive position other than pitcher, the team's DH role ends. None of this permits Devon to pitch again after being replaced as pitcher.
