When an MLB All-Star is injured and cannot play, their replacement is determined by a combination of the player ballot and the Commissioner’s Office. If a fan-elected starter gets hurt, the player on the active roster who received the next highest number of votes from their peers at that position takes over the starting job. The league then handpicks a new player to fill the newly vacant spot on the overall roster.
For reserve players elected by their peers, the next man up on the player ballot simply moves onto the team. But if the top finishers on that ballot are already on the roster, the Commissioner’s Office steps in to make the final choice. This process kicks in constantly during the weeks leading up to the Midsummer Classic. Baseball is a grind. Players get banged up in June and July. The league has to scramble to ensure the rosters stay at full capacity: 20 position players and 12 pitchers per side.
Fans spend weeks voting for their favorite players to start the game. But the moment the polls close, the reality of a long season sets in. Foul balls fracture fingers. Pitchers tweak their elbows. Outfielders pull hamstrings while stealing second base. The roster you see announced on television is rarely the exact group of guys who line up on the foul lines during the national anthem.
The injury replacement system is a vital piece of the baseball calendar. It keeps the game competitive, ensures the pitching staffs are deep enough to avoid overworking anyone, and gives a few lucky snubs a last-minute flight to the biggest party of the summer.
How the Injury Replacement Process Works
Replacing an injured star is not just about grabbing the next famous guy off the couch. According to the roster rules published by Major League Baseball, the league follows a specific chain of command. The player ballot is the main engine. Long before the game, players, coaches, and managers fill out their own ballots to select the pitching staff and the reserve position players. This clubhouse vote creates a built-in pecking order for every position on the diamond.
If a starting outfielder pulls a hamstring, the league looks at the player ballot. The outfielder who finished second in peer voting (and is already on the roster as a reserve) gets bumped up to the starting lineup. That leaves a hole on the bench. The Commissioner’s Office then selects a new roster replacement to fly to the game.
The rules give the league some flexibility when filling that bench spot. An injured position player does not have to be replaced by someone who plays the exact same spot on the field.
- Pitcher for Pitcher: If a pitcher drops out, another pitcher must take his place. The league cannot replace a starting pitcher with an extra designated hitter.
- Position Flexibility: If an outfielder gets hurt, the league can replace him with an infielder, a catcher, or another outfielder. This helps the league balance the bench based on who is available and willing to play.
- The Reserve Queue: If a backup player gets hurt, the next player down on the player ballot gets the call. If those guys are all already on the team, the league makes an executive choice.
The Commissioner’s Office also has a strict mandate to keep every MLB franchise represented. The initial roster must have at least one player from all 30 teams. But if a team’s only All-Star gets hurt, the replacement does not have to be their teammate. The initial selection checks the box for that franchise. The league can look anywhere across the league for the replacement, saving them from having to pick a mediocre player just to fulfill a quota.
Why Teams Use This / When It Applies
Injuries are the most obvious reason a player bows out, but they are not the only reason the replacement protocol activates. Pitchers have their own specific set of rules based on the regular-season schedule.
Starting pitchers throw every fifth day. The All-Star Game happens on a Tuesday. Any pitcher who starts a regular-season game for their club on the Sunday right before the All-Star break gets a special exemption. They can choose to pitch in the All-Star Game for a single inning, or they can opt out entirely to protect their arm. If a guy throws 100 pitches on Sunday, throwing again on Tuesday is a bad idea.
When a Sunday starter opts out, the Commissioner’s Office steps in and picks a replacement. The original pitcher is still an official All-Star selection in the record books. They just give up their spot on the active game-day roster so someone else can actually take the mound. Clubs can also request usage accommodations if a pitcher recently came off the injured list or has thrown too many innings in the first half of the season.
Players also drop out for personal reasons. Sometimes a guy has a nagging injury that is not bad enough for the injured list, but he wants the four days off to rest. The league accommodates these requests and fires up the replacement process. The goal is to put on a good show without jeopardizing the second half of the season for the players involved.
Famous Examples from Major Games
Replacements happen every single year. The roster turnover between the announcement show and the actual game is consistently high.
Medical and injury reports from Fox Sports covering the June 2026 bone fracture suffered by Cleveland Guardians star third baseman José Ramírez show how quickly the league has to pivot when a top vote-getter goes down. This was a tough blow for Cleveland, and it forced the league to activate the backup protocols just weeks before the game. Sudden mid-season casualties like the Ramírez injury are a normal part of the process.
The 2025 season saw a large wave of roster changes. Over a dozen replacement players ended up making the trip due to injuries, opt-outs, and Sunday starters resting. Isaac Paredes was one of the guys who got the call to fill in for injured stars, proving that having a great first half can eventually pay off even if you miss the initial cut.
Documentation from sports analysts at Just Baseball highlights that the process of picking these late additions often stirs up debate among fans and sports talk radio. The Commissioner’s Office has to balance pure statistical merit against the entertainment value of the game. In 2025, the league selected rookie pitcher Jacob Misiorowski as a replacement. He had only made a handful of major league starts at that point. Some fans loved seeing a fresh face with a wild fastball. Others were angry that established veterans with better overall stats were left sitting at home. The tension between putting on a television show and rewarding a full half-season of work makes the replacement debates a loud part of the baseball calendar.
The Ripple Effect on Player Contracts
Making the All-Star team is not just about pride. It has real financial consequences for the players involved. Many contracts include performance bonuses that trigger if a player is named an All-Star.
When an injured player bows out, they keep their All-Star status and they get to cash their bonus check. But the replacement player who steps in also gets the official status. This means a late injury can actually result in the league paying out more bonus money across the board.
Young players in their arbitration years also benefit hugely from being named a replacement. When a player goes to an arbitration hearing to fight for a higher salary, having an All-Star appearance on their resume gives them serious bargaining power. The arbitrators do not distinguish between a guy who got ten million fan votes and a guy who got a phone call from the Commissioner on Sunday night because three other outfielders tweaked their backs. An All-Star is an All-Star.
This financial reality is why players rarely turn down the invitation to be a replacement, even if it means canceling a family vacation at the last minute. The long-term bump in career earnings is too good to pass up.
Common Misconceptions
Fans often misunderstand how the All-Star record books work. Some think that if a player gets hurt and cannot play, they lose their All-Star status. That is completely false. If you are voted in by the fans or selected by your peers, you are an All-Star forever, even if you watch the game from your couch in a walking boot.
Another myth is the “lesser All-Star” idea. People sometimes dismiss replacement players as fake All-Stars because they were not the first choice. But the record books do not care how you got there. An injury replacement gets the exact same line on their Baseball Reference page. Decades from now, nobody remembers who was a starter and who was a Sunday replacement. They just count the total number of appearances.
There is also confusion about the “one player per team” rule. Fans of a struggling franchise will panic if their only good player gets hurt, assuming the league will just pick another guy from their terrible roster to fulfill the quota. The league does not do that. Once the initial roster satisfies the representation rule, the league is free to pick the best available player from any team to fill the injury hole.
Finally, people assume the managers of the All-Star teams pick the replacements. That used to be true, but the league changed the rules to remove the managers from the selection process. The managers still set the batting order and pick the starting pitcher, but they do not decide who replaces an injured guy. The player ballot and the Commissioner’s Office handle all of that now, removing any accusations that a manager is just picking his own guys.
Do injured MLB All-Stars still get credit for the selection?
Yes. If a player is voted into the All-Star game but cannot play due to an injury, they still receive official credit for the All-Star selection on their career record. The history books recognize them the same as the players who actually take the field.
If a team’s only All-Star is injured, does the replacement have to be from that team?
No. MLB rules mandate that every team is represented during the initial roster construction. If that sole representative cannot participate, the replacement chosen by the league does not have to be a teammate. The league considers the representation rule fulfilled by the initial selection.
Do All-Star replacements have to play the exact same position?
Not necessarily. While pitchers must be replaced by pitchers to protect the arms in the bullpen, position players have more flexibility. The league can replace an injured outfielder with an infielder, or vice versa, depending on what the roster needs for the later innings.
Who picks the injury replacements?
It is a combined effort. If a starter is injured, the player ballot dictates who takes over the starting role. The open spot on the overall roster is then filled by the Commissioner’s Office. For player-elected reserves, the next man up on the player ballot gets the nod, unless the league has to step in because the ballot leaders are already on the team.
