A standard MLB regulation game runs nine innings, with each inning split into a top and bottom half. The visiting team bats in the top half. The home team bats in the bottom half. Each half-inning ends after three outs against the batting team.
Each MLB nine-inning game contains 18 half-innings under normal conditions. Walk-off scenarios end the game without a final bottom half. The home team triggers a walk-off when leading after the visiting team’s final at-bat.
Regular-season games tied after nine innings continue under the Automatic Runner Rule, in place since 2020. Each extra inning starts with a runner placed automatically on second base. That runner is typically the batter who made the last out in the previous half-inning. MLB introduced the Automatic Runner Rule to shorten extra-inning games and reduce pitcher fatigue.
Postseason extra innings differ from the regular-season format. Playoff games begin extra innings with empty bases. The full nine-inning competitive structure carries into October baseball without the ghost-runner shortcut.
MLB classifies a game as official after five completed innings, or four and a half if the home team leads. Weather-shortened games end at that threshold when conditions prevent further play. Suspended games may also resume later in the schedule under specific MLB rules.
MLB implemented the pitch clock at the start of the 2023 season. The single rule cut average nine-inning game length from 3:04 in 2022 to 2:40 in 2023. The 24-minute drop ranked as the largest single-season pace-of-play change in MLB history.
A third pickoff attempt is allowed only if the pickoff retires the runner. Failed third attempts are charged as a balk.
MLB recorded one pitch-clock violation per every 5.2 games during 2025. The low violation rate reflects player adaptation to the rule. Pitchers and batters internalized the timing windows after three seasons under the system.
The 2025 average rose 2 minutes from 2024 despite the pitch clock staying in place. MLB attributes the increase to longer plate appearances and slight rebound in offensive volume. The 2025 figure still ranks as one of the fastest MLB averages since the 1980s.

MLB game length climbed steadily from the 1980s through the 2021 peak of 3 hours 11 minutes. The 2021 figure represented the longest average in modern MLB history. Fan complaints about game pace reached critical mass that year.
The longest MLB regular-season game by clock time was Chicago White Sox vs. Milwaukee Brewers on May 8, 1984. That game ran 8 hours 6 minutes across 25 innings. The longest Triple-A game was Rochester Red Wings vs. Pawtucket Red Sox on April 18, 1981. That contest lasted 8 hours 25 minutes across 33 innings. Both records predate modern extra-inning rules and remain unlikely to be broken under current MLB structure.
Postseason games typically run 20 to 30 minutes longer than regular-season contests. Wild Card games averaged near 2:58 during the 2024 postseason. Division Series and Championship Series games averaged near 3:05. Playoff games face no ghost-runner rule, drawing out tight contests in extra innings.

MLB introduced the Automated Ball-Strike Challenge System, known as ABS, for the 2026 season. Each team starts every game with 2 challenges on ball-strike calls. Successful challenges are not deducted from the team’s total. Teams that exhaust both challenges receive one additional challenge if the game goes to extra innings.
Only the pitcher, catcher, or batter may initiate a challenge. The player must tap their helmet or cap immediately after the call. Any delay voids the challenge attempt. The review uses computer-tracked Hawk-Eye strike-zone measurement against a player-specific zone. The ruling returns within seconds via the umpire’s earpiece.
MLB also added designated coaching boxes for first-base and third-base coaches starting in 2026. Coaches who step outside the box during live play may trigger interference rulings. The change reduces field disruption and supports faster between-pitch play. Pitch-clock specifications remain unchanged from the 2024 adjustment.
ABS challenges add roughly 17 seconds per successful review, per MLB pre-season testing data. Teams averaged 1.4 challenges per game during 2025 minor league trials. Total expected impact on 2026 game length is under 60 seconds per game on average.

MLB game length now sits below NFL averages and aligns with NBA and NHL game times. The pitch clock pulled baseball closer to other major US sports for total broadcast commitment.
Baseball remains the only major US sport without a game clock. The structure permits unlimited extra innings under postseason rules. MLB game length carries more variance than clock-based sports.
Fans attending an MLB game should budget 3 hours total. That window covers pregame parking, seating, the game itself, and exit traffic. Weekday games rarely extend past 9:30 PM local time. Postseason games and extra-inning matchups require additional time allocation.
