Major League Baseball (MLB) has several key dates throughout the season, but one of the most pivotal is the MLB trade deadline. This annual deadline represents the last opportunity for teams to make trades without going through waivers, and it can drastically shift the trajectory of the season for many clubs. Whether a team is in contention and looking to strengthen its roster, or out of the playoff race and looking to build for the future, the trade deadline is a critical time.
In this article, we’ll explore when the MLB trade deadline occurs, why it matters, how it works, recent trends, and what fans should expect.
What Is the MLB Trade Deadline?
The MLB trade deadline is the final day that teams can make trades without requiring waivers on the players involved. After the deadline, rosters become relatively set for the rest of the season. This makes it one of the most anticipated times of the year for players, managers, analysts, and especially fans.
The trade deadline typically serves two major purposes:
- Buyers (contending teams) try to acquire players who can help them win in the postseason.
- Sellers (non-contending teams) look to trade away veterans in exchange for young prospects to rebuild.
When Is the MLB Trade Deadline in 2025?
For the 2025 MLB season, the trade deadline is expected to be on July 31, 2025, at 6:00 PM Eastern Time (ET).
This date follows the recent tradition of holding the deadline near the end of July. Prior to 2022, the deadline sometimes shifted due to the calendar or collective bargaining agreements, but MLB has largely standardized it to fall on or around July 31, unless that day is on a weekend or holiday, in which case it may move slightly.
Why Does the Trade Deadline Matter?
The MLB trade deadline is crucial because it’s the last chance for teams to improve their rosters for a playoff push or build for the future without limitations. After this date:
- No trades can be made without players passing through waivers.
- Players must be on a team’s roster by August 31 to be eligible for the postseason.
- Teams must rely on internal call-ups or free agents to fill any roster holes.
This makes the days leading up to the deadline a whirlwind of speculation, rumors, and blockbuster deals.
Key Trade Deadline Terms to Know
Here are some important terms that are frequently used around the MLB trade deadline:
- Prospect: A young player, typically in the minor leagues, with potential to become a major league star.
- Rental Player: A player who will become a free agent at the end of the season and is acquired just for the playoff push.
- Blockbuster Trade: A high-profile deal that often includes star players and multiple prospects.
- Buyers vs. Sellers: Teams either buying to contend or selling to rebuild.
Understanding these terms can help fans follow the action more closely during trade season.
How Does the Trade Deadline Work?
Before the trade deadline:
- Teams negotiate trades that can involve major league players, prospects, and even international signing slots.
- All trades must be approved by the MLB office and finalized before the 6:00 PM ET deadline.
- After the deadline, players must pass through waivers to be traded, which gives other teams a chance to claim them.
In recent years, waiver trades after the deadline have been eliminated, making July 31 a true cutoff point for roster moves.
