Pitching will look a little different at the World Baseball Classic in 2026.
MLB fans will have their eyes fixed on the mound throughout the two-week tournament, with gifted arbalests like Paul Skenes, Yoshinobu Yamamoto and Ranger Suarez all set to take the ball for their respective countries. The matchups should prove enticing; Samurai Japan and the Dominican Republic are teeming with rotational depth, while the Americans boast the two reigning Cy Young winners.
When the sport’s finest arms take to the stage across the United States, Japan and Puerto Rico, they’ll be asked to abide by distinctive edicts, some of which do not exist within the professional game in the United States.
With that, here’s a look at the pitching rules for the 2026 World Baseball Classic.

World Baseball Classic pitcher rules
Pitch counts
Those participating in the 2026 World Baseball Classic will have to abide by strict pitching restrictions. Hurlers will be greeted by pitch limits throughout the tourney, with the bounds being loosened over the course of each round. They are as follows:
- Pool play: 65 pitches
- Quarterfinal round: 80 pitches
- Semifinals and championship round: 95 pitches
Pitchers are permitted to exceed the given limits to finish a plate appearance. Intentional walks are not counted towards the pitch count.

Pitcher usage limits
Pitch counts are not the only way the World Baseball Classic places limits on pitcher usage. Twirlers are only permitted to pitch on two consecutive days if they throw 29 or fewer pitches in a previous outing. They’re not allowed to pitch on three straight days.
The number of pitches a player throws will have an impact on how long it will be until they can pitch again. Pitchers can only throw on two consecutive days if they don’t throw more than 29 pitches in a previous outing. Pitchers can never pitch on three straight days.
Hurlers who toss between 30 and 49 pitches have to sit at least one day before making another appearance on the mound. If a pitcher exceeds the 50-pitch count, they’ll have to wait at least four days before taking the bump again.
If a pitcher throws between 30 and 49 pitches, he would have to go at least one day between outings. More than 50 pitches, and the player must wait at least four days until he can pitch again.
The mercy rule also figures to prevent teams from expending too much out of its pitching staffs. During pool play, games will be called if a team leads by 15 or more runs after the fifth inning or 10 or more runs after the seventh inning.

Three-batter minimum
The three-batter minimum returns to the competition in 2026, three years after making its World Baseball Classic debut. Initially implemented during the 2020 MLB season, the three-batter minimum rule blots team’s ability to exhaust their pitching depth during contests, ostensibly spurring on the improved pace of play.
Not all of the pace of play edicts that have come to shape the new-look MLB will come into effect during this year’s World Baseball Classic. This one will, however, with bullpen arms tasked with facing off against three batters before disappearing once more into the dugout. Pitchers can evade that fate if they escape an inning prior to facing their third batter.
However, if a thrower faces one batter in an inning, gets an out to complete the frame, and then returns for more action, they’ll have to duel at least two consecutive batters before exiting the contest.

Pitch clock
After spurning the pitch clock in 2023, the World Baseball Classic will feature the apparatus during the 2026 tournament. Pitchers will have to deliver their offerings in 15 seconds with no runners on base and 18 seconds with runners on base, the same as in MLB.
