If you want an idea of how much of a seller’s market has developed leading up to Monday’s trade deadline, you only need to look at the biggest deal that happened on Friday: the Marlins’ acquisition of Andrew Cashner, Colin Rea and Tayron Guerrero for Carter Capps, Jarred Cosart, Josh Naylor and Luis Castillo.
Cashner has been below replacement level this year and is a rental. Rea has been below replacement level this year and is under team control through 2021. Guerrero is 25, has two innings of major league experience and owns a 4.10 ERA for his minor league career, including 5.
