The New York Mets had a very talented roster coming into the 2026 season.
That said, they dealt with injuries (and made trades).
One of those moves was to send David Peterson to the Chicago Cubs.

Peterson is now a free agent.
He will be available to sign with any team in the MLB this winter.

Peterson finished the 2026 season going 9-8 with a 4.79 ERA in 32 games (23 starts).
He also appeared in one MLB playoff game for the Cubs.
There is no question that the 31-year-old will be an intriguing free agent to hit the market.
Looking At Peterson’s MLB Career
Peterson was picked in the 1st round of the 2017 MLB Draft.
Before the trade to Chicago, he had spent the first 6.5 seasons of his career with the Mets.
In 2025, Peterson made the MLB All-Star Game.
During the 2024 season, Peterson went 10-3 with a 2.90 ERA in 21 starts.
He was also with the Mets when they made the NLCS (2024).
