SB Nation contributor Jeff Irving has published a mock trade proposal that would send Arizona Diamondbacks star Ketel Marte to the New York Mets. The article, published on November 8, 2026, outlines a hypothetical deal centered on the Diamondbacks' versatile infielder and 2024 National League MVP runner-up.
Marte, who wears number 4 for Arizona, is coming off a season in which he posted a .292 batting average with 36 home runs and 95 RBIs while playing multiple positions. The 30-year-old switch-hitter is under team control through 2027 on a club-friendly contract that includes a 2028 option.
The proposal comes as the Mets look to build around a core that includes Francisco Lindor and Pete Alonso, while the Diamondbacks weigh their competitive window after a 2023 World Series appearance. Any actual trade would require significant prospect capital heading to Arizona given Marte's production and contract status.
