Both Chris Paddack and Dinelson Lamet were never part of the San Diego Padres plans but were openly welcomed as the former was an eighth-round draft pick of the Miami Marlins in the 2015 MLB Draft. He came over to the Friars in the Fernando Rodney deal in June 2016, and not a month after being traded, Paddack was diagnosed with a torn UCL. He needed Tommy John surgery, and his season was done.
Likewise, Lamet was originally signed by the Philadelphia Phillies as an international free agent in 2012, but an error in his paperwork allowed the Padres to swoop in a sign him two years later.
