On Monday, MLB Trade Rumors reported that Oscar Taveras switched agents from Melvin Roman (the agent for Yadier Molina and Jaime Garcia) to Rob Plummer. Plummer is also the agent for Carlos Martinez, meaning that he represents two of Future Redbirds' top four prospects in the industry's best farm system, at least according to Baseball America and John Sickels. Maybe we should get to know this guy. If Plummer's name sounds familiar, maybe this ESPN story from 2004 will explain it: Plummer, who is based in New York, has represented several Dominican players who have received seven-figure bonuses, including Los Angeles Dodgers' prospect Joel Guzman, owner of a record $2.25 million bonus, set in 2001. He was also the agent who blew the whistle in 1997 on the Florida Marlins for signing underage pitcher Ricardo Aramboles, who was 14 when he signed for $5,500.
