Jerry Koosman, one of the defining arms of the Mets’ first golden era, has died at 83.
The left-hander was a cornerstone for the 1969 World Champion Mets and the 1973 National League champions, and his place in franchise history is secure: he’s in the Mets Hall of Fame, his No. 36 is retired, and he remains one of the most recognizable figures from that era.
Koosman’s path to Queens was unusual. Born in Appleton, Minnesota, he was discovered while serving in the military, and the Mets signed him after his service ended.
He reached the majors in 1967, then became a full-time piece of the rotation in 1968 and immediately looked the part. That season, he went 19-12 with a 2.08 ERA and 178 strikeouts in 263.2 innings, then finished second to Johnny Bench in Rookie of the Year voting.
His best-known work came the next year. Koosman turned in another strong season in 1969 and won two games in the World Series, throwing 17 and two-thirds innings across those two starts. He was also awarded the ball Cleon Jones caught for the final out of the game.
For years after that, Koosman held down the No. 2 spot behind Tom Seaver and kept piling up quality seasons. In 1976, he won 21 games and finished second in Cy Young voting. After the Mets’ rough 1978 season, he asked for a trade and was dealt to the Twins for Greg Field and, as a player to be named later, Jesse Orosco.
Across 12 seasons with the Mets, Koosman went 140-137 with a 3.07 ERA and made the All-Star team in 1968 and 1969. His 140 wins are the third-most by a Mets pitcher, behind Seaver and Dwight Gooden.
His career had one more big spike after leaving New York. Koosman had a fantastic 1979 season with the Twins, but he never quite reached those heights again.
He spent two and a half seasons with Minnesota, 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.
The Mets inducted Koosman into their Hall of Fame in 1989 and retired his number in 2021, making him just the third player in franchise history to receive that honor.

Twins Just Took Another Quiet Bullpen Miss
Another bullpen arm has slipped through the Twins fingers, this time with the Cubs stepping in to claim Eric Orze off waivers and add him to their 40-man roster. For Minnesota, it is the kind of quiet transaction that barely registers in the moment but can still matter over the long haul, especially for a pitching staff that is always trying to find usable innings without spending heavily to get them.
Orzes path has already been a winding one since his major league debut in 2024, and he now gets another chance to carve out a place in a bullpen that has some openings to sort through. Chicagos relief group was below average in 2026 and has seen several pitchers reach free agency recently, so the opportunity is there if Orze can make a case for himself in spring and beyond.

Twins Enter A Pivotal Offseason With A Roster Problem Exposed
The Brewers run to a World Series title offered a sharp reminder of how aggressively a contender can reshape itself when it sees value at the right moment. For Minnesota, the comparison lands uncomfortably. Over the past decade, the Twins have mostly stayed put, and the result has been a familiar kind of middle ground that has kept the roster competitive enough to matter without ever quite pushing it into a higher tier.
Now the front office heads into an offseason with real roster questions hanging over it, and the stakes feel higher because the clubs current core is no longer as simple to manage as it once was. The Twins have several players whose place in the long-term picture is less certain than it used to be, and the decisions made in the coming months could say a lot about whether this group is finally due for a more aggressive reset or more of the same incremental approach.

Twins May Have A Catching Trade Chip They Can't Rush To Move
The Twins could have a little more flexibility than usual if they decide to shop for pitching this offseason, and catching prospect Khadim Diaw is part of that conversation. Minnesotas depth behind the plate gives the front office some room to consider moving a young catcher in the right deal, especially if the goal is to add major league arms without dipping too far into the top of the farm system.
Diaws name stands out because of how much he has raised his stock in a short time, but this is still a speculative read on where the Twins might look rather than a sign that talks are underway. The bigger point is that Minnesota may have a trade chip in a position of strength, and the challenge will be deciding whether the pitching help is worth parting with a catcher the organization clearly values.
