MLB Trade Rumors The Marlins are selecting the contract of right-hander Luís Madero, Jordan McPherson of the Miami Herald was among those to relay (Twitter link). Lefty Daniel Castano was optioned to Triple-A Jacksonville, while right-hander Jorge Guzman was transferred to the 60-day injured list to clear 40-man roster space. Madero has bounced between a few organizations in his pro career but has yet to make his MLB debut. Originally signed by the Diamondbacks as an international amateur, he was sent to the Angels at the 2017 trade deadline for reliever David Hernández. Madero eventually worked his way onto Los Angeles’ 40-man roster and was named the #19 prospect in the organization entering the 2019 season by Baseball America. He struggled at Double-A that year, though, working to a 5.72 ERA in a pitcher-friendly environment. The Angels designated him for assignment and lost him on waivers to the Giants after the season.
