How Many Baseball Games Per Season in MLB?

Each Major League Baseball (MLB) team plays 162 regular season games per year, resulting in a total of 2,430 games across the entire league. This schedule has been standard since 1961 for the American League and 1962 for the National League.

The Structure of an MLB Season

The modern Major League Baseball season is carefully structured to balance competitive integrity, player workload, and fan engagement. Each of the 30 teams in MLB plays 162 games over approximately six months, from late March or early April through September.

Breakdown of the 162-Game Schedule

• Intradivision Games: Teams play 13 games against each of their 4 division rivals (52 games total).
• Intraleague Games: 6 games against each of 6 teams from the other two divisions in their league (36 games), and 7 games against the remaining 4 teams (28 games).
• Interleague Games: 20 games are played against one division from the opposite league, following a rotating schedule.

Historical Evolution of the MLB Schedule

The number of games in an MLB season has evolved significantly since the league's inception. Early seasons featured far fewer games, but expansion and commercial growth led to longer schedules.

The transition from 154 to 162 games reflected MLB’s expansion from 16 to 20 teams by 1962. Shortened seasons were exceptions caused by labor disputes or global events. The 162-game format remains the benchmark for measuring team performance and player statistics.

Postseason and Additional Games

Beyond the 162 regular season games, teams may participate in postseason play. The number of additional games varies based on playoff success:

• Wild Card Series: Best-of-three (2–3 games)
• Division Series: Best-of-five (3–5 games)
• Championship Series: Best-of-seven (4–7 games)
• World Series: Best-of-seven (4–7 games)

A team that wins all its postseason series can play up to 18 additional games, bringing their total to 180 games in a single year.
