Jerry Koosman, one of the defining pitchers from the Mets’ first golden era, has died at 83.
The left-hander was a key part of both the 1969 World Champion Mets and the 1973 National League champions, and he remained one of the most recognizable figures from that era. The Mets honored him with a place in their Hall of Fame, and his No. 36 has been retired by the club.
Koosman’s path to Queens began 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 Mets pitcher in 1968 and immediately made his mark. 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.
His 1969 season was just as memorable. Koosman won two games in the World Series, working 17 and two-thirds innings across those two starts, and he was awarded the ball Cleon Jones caught for the final out of the game.
For years, Koosman settled in as the Mets’ No. 2 starter behind Tom Seaver, and he put together plenty of strong seasons in that role. One of his best came in 1976, when he won 21 games and finished second in Cy Young voting. After the Mets’ disastrous 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.
Across 12 seasons with the Mets, Koosman posted a 140-137 record with a 3.07 ERA. He was an All-Star in 1968 and 1969.
His career had one more big spike in 1979 with the Twins, but after that it never quite reached those heights again. He spent two and a half seasons in 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.
Koosman still ranks third in Mets pitching wins with 140, behind Seaver and Dwight Gooden. The Mets inducted him into their Hall of Fame in 1989 and retired his number in 2021, making him just the third Mets player to receive that honor.

Knicks Suddenly Have A Trade Opening They Cant Ignore At Center
The Knicks search for a dependable backup center has become one of the more obvious roster questions around the team, especially with the season still taking shape and the frontcourt depth under the microscope. Milwaukees rough start has only added another layer to the conversation, since a struggling club can quickly move from holding firm to listening on pieces that might not fit its long-term direction.
Among the names floating around, Kelel Ware stands out as the more intriguing but less likely target, while Jericho Sims looks like the cleaner fit for New York if the Bucks decide to deal. Sims would come at a lower cost and offers the kind of familiar, straightforward depth the Knicks could use behind their main rotation, but for now it remains more of a possibility than a move.

Mike Brown Is Sending An Early Message With Knicks Rookie Tyler Kolek
The Knicks win over the Nets at Madison Square Garden offered another small but notable glimpse into how Mike Brown is sorting out his rotation early in the season. With New York now 3-4, Brown gave rookie point guard Tyler Kolek a brief look and kept leaning on the kind of depth pieces that can matter as the schedule wears on, while Landry Shamets 22 points helped carry the offense alongside Jalen Brunson and OG Anunoby.
Tyler Koleks five-minute stint was the kind of early-season opportunity that can say plenty about a coachs view of a young guard, especially on a roster still settling into roles. Jose Alvarado also made his return and logged nine minutes with a block, adding another layer to a backcourt mix that Brown seems willing to test as the Knicks try to find the right balance behind their top scorers.

Tyler Kolek Just Made The Knicks Backup Point Guard Battle Real
Tyler Kolek has turned the Knicks backup point guard conversation into a real one early in the 2026-27 season. His offensive play has stood out, and the assist-to-turnover numbers have backed up what the eye test has shown. Even with Jose Alvarado back from injury, Kolek has kept earning trust, which says plenty about where he sits in the rotation right now.
Against the Brooklyn Nets, that trust showed up in a big fourth quarter. The Knicks gave Kolek meaningful minutes down the stretch, and he delivered the kind of plays that helped push New York into the lead. If this is the way the battle is shaping up, the Knicks may already have a clear answer for who handles the second unit when the game gets tight. [Read more 🡒]
