Thirteen free agents received qualifying offers from their former teams Monday before free agency officially began at 5 p.m. E.T., sources told ESPN's Jeff Passan. Among those tendered the offer, which is a one-year, $21.05 million contract for the 2025 season:

• New York Yankees outfielder Juan Soto

• Baltimore Orioles right-hander Corbin Burnes

• Houston Astros third baseman Alex Bregman

• Atlanta Braves left-hander Max Fried

• Milwaukee Brewers shortstop Willy Adames

• New York Mets first baseman Pete Alonso

• Orioles outfielder Anthony Santander

• Los Angeles Dodgers outfielder Teoscar Hernandez

• Boston Red Sox right-hander Nick Pivetta

• Arizona Diamondbacks first baseman Christian Walker

• Mets left-hander Sean Manaea

• Mets right-hander Luis Severino

• Cincinnati Reds right-hander Nick Martinez

The players have until 4 p.m. ET on Nov. 19 to decide whether to accept the offer, which is calculated annually based on the mean average annual value of Major League Baseball's 125 biggest contracts.

The most sought-after free agents have historically rejected the proposal to enter free agency in search of a multiyear contract. Just 13 of 131 players have accepted a qualifying offer since it was introduced following the 2012 season. Last year, all seven players presented the deal, valued at $20.325 million, turned it down.

Clubs can give a player a qualifying offer only if the player was with the team continuously from opening day and has never received a qualifying offer before.

Dodgers right-hander Walker Buehler, San Diego Padres outfielder Jurickson Profar, and Yankees second baseman Gleyber Torres were among the free agents not extended the qualifying offer.

Teams that lose a player who received a qualifying offer receive a compensation pick. Clubs that sign players who rejected the qualifying offer before the amateur draft the following year must surrender draft compensation and could also lose international bonus pool money. The possible penalties have not affected top-tier free agents' earning potential, but they have hampered the market for midtier players.

Teams that surpassed the competitive balance tax line in 2024 and sign a player tied to a qualifying offer stand to lose their second- and fifth-highest picks in the upcoming amateur draft. They also lose $1 million from their international bonus pool. Revenue-sharing organizations lose their third-highest draft selection. The others lose their second-highest draft pick and $500,000 from their international bonus pool.
