3 best Mets prospects who will be traded before making their MLB debut
3) NY Mets prospect who will be traded before making his MLB debut: Joel Diaz
The Mets don't have any high-end pitching prospects. Matt Allan was supposed to be one, but injuries have completely derailed his development. Other than that, Blade Tidwell is the best pitching prospect the Mets have. Tidwell can be good, but he doesn't have the ace potential that fans get really excited about.
While they don't have high-end guys, they do have a ton of starting pitching prospects in Single-A. The Mets 9-12 ranked prospects are all starting pitchers who are either in St. Lucie (A) or Brooklyn (A+).
The pitcher who I think is furthest away but does have some potential is Joel Diaz. The right hander is just 19 years old with an MLB ETA of 2025 according to MLB Pipeline. He's the 12th ranked prospect in their top-30.
If the Mets want to upgrade the team at the deadline or even next offseason in a trade, and they don't want to give up any high-end guys, someone like Diaz could be on the move.
He had a rough year in St. Lucie posting an ERA approaching 6.00, but looked really good in Rookie Ball in 2021, allowing just three runs in 50.1 innings pitched and striking out 63 batters to nine walks. Diaz can have a future if he keeps developing and the Mets can get something decent if they opt to trade him. Teams are always looking for pitching, and while the Mets don't have blue chip pitching prospects, they do have decent ones.
