Hey there, Jays fans! If you’ve ever been reading a roster update or listening to a game broadcast and found yourself wondering, “What exactly does ‘option year’ mean?” or “What is a ‘non-roster invitee’?”, you’re in the right place. The world of MLB roster management has its own unique language. This glossary is here to decode the key terms you need to know to follow the ins and outs of your Toronto Blue Jays.


40-Man Roster


This is the master list of players under contract with the Toronto Blue Jays organization who are protected from being selected by other teams in the Rule 5 Draft. It includes all players on the 26-man active roster, as well as those on the Injured List, Restricted List, and players with "options" who are in the minor leagues. Managing this list is a year-round job for GM Atkins.

26-Man Roster (Active Roster)


This is the group of players eligible to play in MLB games on any given day during the regular season. It typically consists of 13 position players (like Vladimir Guerrero Jr. and Bo Bichette) and 13 pitchers (like Kevin Gausman and Jordan Romano). This is the squad you see take the field at the Rogers Centre.

60-Day Injured List (60-Day IL)


A roster designation for players who are seriously injured and will be out for an extended period. Placing a player here frees up a spot on the 40-man roster, which is crucial for roster flexibility. The player must miss at least 60 days of the regular season.

10-Day Injured List (10-Day IL)


Used for less severe injuries or short-term ailments. A player on the 10-Day IL must miss a minimum of 10 games. This is a common tool Manager Schneider and the training staff use to give players like George Springer time to heal without playing short-handed.

Option / Option Year


When a player is on the 40-man roster but not on the active 26-man roster, they can be sent to the minor leagues. This is called being "optioned." Each player has three "option years" where they can be moved up and down freely. Once options are exhausted, the player must be designated for assignment to be sent down.

Designated for Assignment (DFA)


A procedural move that removes a player from the 40-man roster. The club then has seven days to trade the player, release him, or send him to the minors (if he has options remaining). It’s often the first step when a team needs to create a roster spot.

Waivers


A process where other MLB teams can claim a player who has been designated for assignment. Players are often placed on "outright waivers" (to send to minors) or "release waivers" (to let go entirely). Waiver priority is typically based on the reverse order of the league standings.

Non-Roster Invitee (NRI)


A player invited to Major League spring training who is not on the 40-man roster. These are often veteran players or top prospects, like a young Alejandro Kirk once was, trying to earn a spot. A strong spring can force the front office to make a tough decision.

Service Time


The total number of days a player has spent on an active MLB roster or the Major League injured list. Service time is critical as it determines eligibility for salary arbitration (after 3 years) and free agency (typically after 6 years).

Arbitration-Eligible


A player with between three and six years of MLB service time can file for salary arbitration if he and the club cannot agree on a contract. An independent arbitrator chooses either the player’s or the team’s salary figure. This is where stars like Bo Bichette negotiate their value before hitting free agency.

Free Agency


A player with six or more years of MLB service time becomes a free agent, able to sign with any team. This is the open market where the Blue Jays have made big splashes, signing players like Kevin Gausman and George Springer to bolster the roster for a World Series run.

Club Control


The period of time a team retains the rights to a player before he reaches free agency. This includes his minor league years and his first six years of MLB service. Maximizing the production of cost-controlled players is key to building a sustainable contender in the tough AL East.

Rule 5 Draft


An annual draft held in December where teams can select eligible players not on another club's 40-man roster. The selected player must remain on the drafting team's active 26-man roster for the entire following season or be offered back to his original team.

Trade Deadline


The last day of July is the official deadline for teams to make trades without players having to pass through waivers first. It’s a frenzied time where contenders like the Jays look to add the final piece for a playoff push, while other teams may trade away veterans.

Wild Card


A playoff berth awarded to the non-division-winning teams in each league with the best records. With the powerhouse American League East, the Wild Card is often a primary route to the postseason for the Jays.

Payroll (Luxury Tax Threshold)


The total sum of salaries paid to players. MLB has a Competitive Balance Tax (or "luxury tax") threshold—a soft salary cap. Teams that exceed it pay a tax. How close the Toronto Blue Jays operate to this threshold is a constant topic for Ross Atkins and the front office.

Platoon


A strategy where two players split time at one position, often based on the opposing pitcher's handedness (e.g., a left-handed batter plays against right-handed pitchers). It’s a way to maximize matchups and production.

Utility Player


A versatile position player capable of playing multiple defensive spots competently. Having a reliable utility player provides Manager Schneider with crucial flexibility for in-game moves and covering injuries.

Starting Rotation


The group of pitchers, usually five, who take turns starting games in a set order. The stability and performance of the rotation, featuring Jose Berrios, Yusei Kikuchi, and Kevin Gausman, is the foundation of any successful season.

Bullpen


The collective term for relief pitchers who enter the game after the starting pitcher. Roles include long relievers, setup men, and the closer (Jordan Romano). A reliable bullpen is essential for protecting late-game leads.

Closer


A relief pitcher specializing in securing the final outs of a close game to earn a save. It’s a high-pressure role, and a dominant closer like Romano is a luxury that can define a team's late-game identity.

Designated Hitter (DH)


A position in the American League (and now MLB-wide) for a player who bats in place of the pitcher but does not play a defensive position. It allows a powerful bat like Vladimir Guerrero Jr. to focus solely on hitting.

Call-Up


When a player is promoted from the minor leagues to the active MLB roster. This can happen due to injury, performance, or roster expansion in September. It’s the dream moment for any prospect.

Optioned Down


The opposite of a call-up. When a player on the 40-man roster is sent to the minor leagues to get more playing time or work on specific skills. He uses one of his option years in the process.

Player to be Named Later (PTBNL)


A placeholder in a trade where one team will receive a specified player from a pool of agreed-upon players at a later date, often after a certain period has passed. It adds future flexibility to trade deals.

Understanding these terms gives you a deeper insight into the chess game that is MLB roster construction. From managing service time for young stars to making bold moves at the trade deadline, every decision by Ross Atkins and his team is about building a roster capable of winning the American League East and, ultimately, bringing the World Series championship back to Toronto.
