The Pittsburgh Pirates put together a large international signing class with their 2017-18 bonus pool money. They gave early indications that they would need a second Dominican Summer League team in order to get time for every player, then went all in on that idea in December when Junior Vizcaino took over as the Scouting Director for Latin America.
The biggest signing from this class ended up coming late and only happened after the Pirates acquired bonus pool money in the Andrew McCutchen trade. Then they voided the $230,000 bonus of shortstop Gregori Custodio after they couldn't get the right paperwork to confirm his age.
