Jerry Koosman, one of the defining pitchers of the Mets’ first great era, has died at 83.
The left-hander was part of both the 1969 World Champion Mets and the 1973 National League champions, and he remained one of the most recognizable names from that early run of success. Koosman was inducted into the Mets Hall of Fame in 1989, and the team retired his No. 36 in 2021. He was only the third Mets player to receive that honor.
Koosman’s path to Queens started in Appleton, Minnesota, and the Mets found him while he was in the military. They signed him after his service ended, and he reached the majors in 1967 before becoming a full-time member of the rotation in 1968. That season, he went 19-12 with a 2.08 ERA and 178 strikeouts in 263.2 innings, finishing second to Johnny Bench in Rookie of the Year voting.
By 1969, Koosman was again delivering at a high level. He won two games in the World Series, working 17 and two-thirds innings across those appearances, and he was awarded the ball Cleon Jones caught for the final out of the game.
For years after that, Koosman settled in as the Mets’ No. 2 starter behind Tom Seaver and piled up strong seasons. He won 21 games in 1976 and finished second in Cy Young voting that same year. After the Mets’ rough 1978 season, he asked to be traded and was dealt to the Twins for Greg Field and, later as a player to be named later, Jesse Orosco.
In 12 seasons with the Mets, Koosman went 140-137 with a 3.07 ERA. He made the All-Star team in 1968 and 1969, and his 140 wins rank third in franchise history behind Seaver and Dwight Gooden.
His career continued after leaving New York, but it never again reached the heights of his best years. After a strong 1979 season with the Twins, he spent two and a half seasons there, then two and a half with the White Sox and two with the Phillies before retiring after the 1985 season. He finished with 53.6 bWAR.

Mets Offseason Activity Is Picking Up Faster Than Fans Expected
The Mets offseason started to take shape a little earlier than some fans probably expected, with the club making a handful of small but notable moves as the calendar turns toward winter. New York claimed Jack Anderson and Pierson Ohl off waivers and added Christian Cairo on a one-year major league contract, the kind of roster housekeeping that often signals a front office getting busy before the bigger decisions arrive.
There was also a bit of good news on the player-development side, with Carson Benge named a finalist for the National League Rookie of the Year Award. And for fans already looking ahead to next season, the team moved up the single-game ticket sale date to November 12, another sign that the offseason is picking up steam even as the rest of Major League Baseball sorts through award finalists and roster churn across the league.

Mets Rumored Free Agent Fits Come With One Big Problem
The Mets are already being sized up for the 2027 offseason, and the early free-agent chatter is less about splash and more about fit. Names like Ty France, Adrian Morejon and Jake Bauers have surfaced as possible targets, but each one comes with a different version of the same issue: the roster picture, the money picture and the teams actual needs do not line up neatly.
For a club that is always under pressure to add talent, that creates a familiar kind of offseason frustration. The speculation is easy enough to generate, but the path from rumor to signing is much harder to map when the Mets have to balance what they want with what they can realistically afford and where the roster can actually absorb another piece.

Former Mets Arm Just Became A Painful What-If For This Rotation
Freddy Peraltas career has taken a sharp turn since leaving the Mets at the trade deadline, and it has made his departure look a lot more consequential in hindsight. After landing with the Rays, he settled in and improved his performance enough to restore the kind of market value that once seemed out of reach, turning a midseason move into a potential payday.
ESPN analyst Kiley McDaniel now projects Peralta for a four-year, $96 million deal in free agency, a far cry from the one-year prove-it path many expected when he was struggling in New York. For the Mets, it is the kind of rotation what-if that lingers, because a pitcher who looked like a short-term flier has suddenly become a much more expensive version of himself. [Read more 🡒]
