4 trade destinations for Reds pitcher Sonny Gray

4. The Mariners could trade for Reds pitcher Sonny Gray.

We've already heard about the Seattle Mariners' interest in Reds pitcher Luis Castillo.

But, with Castillo now reportedly off limits, will the Mariners entertain the idea of trading for Sonny Gray?

Seattle surprised a lot of experts and fans alike in 2021, winning 90 games and making a push for the AL Wild Card spot.

The Mariners have been rumored to be after several of the high-level free agent starters this offseason, so trading for Gray isn't too far fetched.

Gray would instantly be the ace of the M's pitching staff. Logan Gilbert and Chris Flexen were two of Seattles's best starter in 2021. Both are pre-arbitration eligible.

The Seattle Mariners have one of the deepest farm systems in all of Major League Baseball.

While it's unlikely that Sonny Gray would fetch a prospect like Julio Rodriguez or Noelvi Marte, but maybe Seattle would be willing to part with one of their young pitching prospects.

George Kirby, Emerson Hancock, and Brandon Williamson are all Top 10 prospects within the Mariners' farm system who will be major league-ready by 2023.

Sonny Gray may still return to the Cincinnati Reds in 2022, but with the ownership and front office looking to cut payroll, the right-hander may be dealt this winter.
