The Mets have extended the one-year, $21.05 million qualifying offer to free agent starting pitchers Sean Manaea and Luis Severino, as well as first baseman Pete Alonso, per Mets president of baseball operations David Stearns.

Any player who receives the qualifying offer has until Nov. 19 to decide whether to accept it or reject.

If a player accepts the Mets’ offer, he’d be back for the 2025 season on a one-year deal.

If a player rejects it, he could still ultimately sign with the Mets, but if he were to sign anywhere else, the Mets would receive compensation in the 2025 MLB Draft.

Last year, seven players received the qualifying offer, and all declined. And according to MLB.com’s Mike Petriello, only 10 percent of offers have been accepted since 2012.

Alonso will all but certainly decline the qualifying offer, as he could end up netting a deal in the five-to-seven year range.

The first baseman earned his fourth All-Star nod as a Met this past season, hitting 34 home runs with 88 RBI. While he had a bit of a down year overall, Alonso delivered in the postseason, blasting an unforgettable three-run home run off of Milwaukee’s Devin Williams in Game 3 of the Wild Card series.

The 32-year-old Manaea, who is coming off a strong season, will likely decline the offer and seek a multi-year deal.

Manaea had a fairly pedestrian first half with the Mets last season, but a midseason tweak to alter his delivery completely changed things for the 32-year-old. Excluding his season finale at Milwaukee, Manaea was outstanding in August and September, pitching to 2.91 ERA while going at least 7.0 innings six times.

He was also very reliable in the postseason, allowing just five earned runs over his first three playoff games, including 7.0 innings of one-run ball against the Phillies in Game 3 of the NLDS.

The 30-year-old Severino is in a similar boat as Manaea in that he will likely get multi-year offers, meaning he’ll probably decline the qualifying offer.

The righty had a nice bounce-back season with the Mets in 2024, pitching to a 3.91 ERA, and perhaps more importantly, ended up making 31 starts — the first time he hit the 30-start mark since 2018 with the Yankees.
