Two MLB teams can finish the 2026 regular season with exactly the same record and still have their postseason fate decided without playing another regular-season game. That is the point that trips up many fans in the final week: there is no Game 163 anymore. Since the expanded playoff format began in 2022, MLB has resolved ties for division titles, Wild Card berths and playoff seeding with predetermined mathematical tiebreakers based on regular-season results.
The easiest way to work out who gets in is to start with the season series. If one tied club won the head-to-head matchup, that club owns the first tiebreaker. Only if the head-to-head result does not separate the teams do you move deeper into division and league records. For three- or four-team ties, the process becomes more involved, but the same idea applies: MLB ranks teams using results they already produced during the regular season rather than scheduling an extra game.
Before 2022, certain ties could produce an extra regular-season tiebreaker game, commonly called Game 163. That changed when MLB expanded the postseason to 12 teams. Under the current format, six clubs from each league qualify: the three division winners and three Wild Card teams. The top two division winners in each league receive byes into the Division Series, while the third division winner and the three Wild Cards play in the Wild Card Series.
MLB explains that mathematical tiebreakers replaced extra tiebreaker games so the postseason can begin promptly and so teams with first-round byes are not left waiting longer while another club plays an extra regular-season game. The current system is described in MLB's official 2026 playoff tiebreaker explanation and its postseason format FAQ.
If exactly two teams are tied for a postseason-relevant position, MLB uses the following sequence. Stop as soon as one step produces a winner.
| Order | Tiebreaker | What it means |
|---|---|---|
| 1 | Head-to-head record | Which team had the better regular-season record against the other tied team? |
| 2 | Intradivision record | Which team had the better record against clubs in its own division? |
| 3 | Intraleague record | Which team had the better record against teams in its own league, AL or NL? |
| 4 | Last half of intraleague games | Compare the tied clubs' records in their later intraleague games, as defined by MLB. |
| 5 | Last half plus one intraleague game | Extend that comparison backward one qualifying intraleague game at a time until the tie breaks. |
For two tied teams, the first question is simply who won the season series. Suppose Club A and Club B both finish 88-74 while competing for the last Wild Card. If Club A went 4-2 against Club B, Club A wins the tiebreaker and receives the berth. There is no neutral-site playoff and no coin flip.
The same principle can decide a division title or a seed. If two division leaders finish with identical overall records but one won the season series, that club ranks ahead of the other for the relevant postseason position.
If the season series does not separate the clubs, MLB next compares each team's record within its own division. This can feel counterintuitive when the teams are from different divisions, but the rule still applies. A tied AL East club can therefore be compared with an AL West club by looking at how each performed against opponents in its respective division.
Example: two Wild Card contenders have the same overall record and split their season series. Team X went 31-21 in its division, while Team Y went 29-23 in its division. Team X wins the tiebreaker at this stage.
If head-to-head and intradivision records are both tied, MLB compares performance against clubs in the same league. For an American League team, that means games against AL opponents; for a National League team, games against NL opponents.
This criterion matters more in the modern balanced schedule because teams play opponents from both leagues. Two clubs can finish with the same overall record while having different records against teams within their own league.
If the first three criteria still do not break the tie, MLB moves to the clubs' records in the last half of their intraleague games. MLB notes that this is based on the applicable later intraleague games on the schedule rather than simply taking the mathematical midpoint of the full 162-game season.
If those records are also identical, MLB extends the comparison backward by one intraleague game at a time. In practice, this means the process keeps adding an earlier qualifying league game until one club has the superior winning percentage over the comparison window.
A three-team tie is harder because the clubs may not have played one another the same number of times, and their head-to-head relationships may form an uneven triangle. MLB first looks at the records the tied clubs posted against one another.
If the three clubs have identical records against each other, MLB proceeds through group versions of the later criteria: intradivision winning percentage, then intraleague winning percentage, then the last half of intraleague games, and then the last-half-plus-one process until the tie is broken.
If the three clubs do not have identical records against one another, MLB examines whether one club clearly performed better against each of the other two. A club that has the better record against both opponents can qualify first. If no single club owns that clean advantage, MLB ranks the three by combined winning percentage in games among the tied clubs.
If two clubs remain tied after that group comparison, those two fall back to the standard two-team procedure. If all three remain tied, the three-team sequence continues through the additional criteria.
Imagine Teams A, B and C all finish 86-76. Team A went 5-2 against Team B and 4-3 against Team C. Because Team A had a better head-to-head record against both other tied clubs, it would take the berth before MLB needs to compare deeper metrics. If no team had a superior record against both rivals, the combined record among the three tied clubs would become important.
This is one of the most confusing September scenarios. Suppose three teams finish tied, two of them are battling for a division crown, and there is also one Wild Card berth available among the same group. MLB does not simply hand out both positions at once.
First, the applicable multi-team tiebreaker determines the division champion. After that team is removed from the equation, the remaining two clubs are compared under the normal two-team procedure to determine the Wild Card berth. That reset matters because the head-to-head result between the two remaining teams can then become decisive.
If four teams are tied for one spot, MLB again begins with head-to-head performance within the tied group. The first question is whether one club had a better record against each of the other three. If so, that club advances.
If there is no such club, MLB compares winning percentage in games among the tied teams. If that still does not separate the field, the sequence moves to intradivision winning percentage, intraleague winning percentage, the last half of intraleague games, and then the last-half-plus-one process.
When only two or three clubs remain tied at one of those stages, MLB switches to the corresponding two-team or three-team procedure for those clubs. The rules are designed to reduce the group until every relevant berth or seed can be assigned.
The same tiebreak framework can affect several postseason consequences:
That is why a season series in April can matter in late September. A team does not have to know in April that it will be tied with a particular opponent six months later for those games to become the first postseason tiebreaker.
Several statistics fans commonly mention are not the opening MLB tiebreaker. Run differential, runs scored, record in the final 10 games and strength of schedule do not jump ahead of the official sequence. The first check in a two-team tie is head-to-head record, followed by the specified division and league criteria.
Likewise, the club listed higher on a standings page is not necessarily ahead because it has a better run differential. MLB's standings can display clubs with identical records in the order produced by the applicable tiebreaker.
Start with the final records and identify exactly what is at stake: a division title, a Wild Card berth, a bye or seeding. Then count how many teams are tied for that position.
Before treating a tied club as safely in or eliminated, verify four things. First, make sure the teams truly finished with the same regular-season winning percentage. Second, confirm whether the tie concerns a division, Wild Card berth or seed. Third, use the correct two-, three- or four-team sequence. Fourth, stop at the first criterion that actually separates the clubs.
If your conclusion depends on a made-up Game 163, a coin flip, run differential or a generic "better second half," go back to the official order. In 2026, MLB postseason ties are decided by the regular-season tiebreak system, with head-to-head results at the front of the line and progressively narrower league-based criteria available when the obvious answer is not enough.
