The Mariners are trading for Reds right-handed pitcher Luis Castillo, per ESPN’s Jeff Passan.
In return for Castillo, the Reds will reportedly receive shortstop Noelvi Marte, right-handed pitcher Andrew Moore, right-handed pitcher Levi Stoudt and middle infielder Edwin Arroyo, according to C. Trent Rosencrans of The Athletic.
Marte (No. 1), Arroyo (No. 3) and Stoudt (No. 5) were three of Seattle’s top five prospects.
Castillo was one of the premier pitchers on the market at the trade deadline, as several teams look to make a playoff push.
