Add Castillo to their possible trade list... The 2020 season really put a damper on all the moves they made last off season. Bauer, Gray and Castillo are possibly the best 1-3 in MLB. Jon Heyman of MLB Network reports that, in addition to Sonny Gray, the Reds have also discussed Luis Castillo with teams in potential trades. The Reds were one of the more aggressive teams last offseason, but Heyman says of the club that "the belt tightening this winter is clear." Castillo is eligible for arbitration for the first time this offseason, so he will be getting more expensive. That said, the 28-year-old is under team control through 2023 and is one of the better starters in the National League, so the ask for him is "appropriately high," per Heyman. Out of Gray and Castillo, Gray would seem to be the much likelier pitcher to be dealt. RELATED: Sonny Gray SOURCE: Jon Heyman on Twitter Dec 20, 2020, 11:13 AM ET
