Reds trade with the Mariners for Luis Castillo included a Top 50 prospect.
Noelvi Marte was the key piece of the Cincinnati Reds return. Marte is widely viewed throughout baseball as a Top 50 prospect. Most outlets even viewed Marte as a fringe Top 20 prospect prior to the start of the 2022 season.
Marte has done nothing this season to jeopardize his standing as the 20-year-old has a slash line of .275/.363/.462 with 19 doubles, 15 home runs, and 55 RBIs at High-A Everett. Keith Law of The Athletic (subscription required) ranked Marte as the 11th best prospect in baseball prior to the season and believes he's no more than two years away from making his major league debut.
MLB Pipeline rated Marte as the 18th best prospect in baseball. The outlet wonders if Marte will end up at third base or possibly even center field by the time he makes it to the big leagues. No matter where Marte lines up, it's assumed that his bat will play.
In addition to Noelvi Marte, the Cincinnati Reds also secured the services of another top shortstop prospect in Edwin Arroyo. The M's second-round pick in 2021, Arroyo is having quite the season at Low-A Modesto. Arroyo is hitting .316/.385/.514 and has 13 round trippers with 67 runs batted in.
Throw in pitching prospect Levi Stoudt and Andrew Moore, and this is quite the haul that Nick Krall brought back in return for Luis Castillo's services. Stoudt will probably make his way to the bigs next season and Moore can touch 102 mph on the radar gun.
