NEW YORK -- San Diego Padres general manager A.J. Preller has been suspended 30 days without pay by Major League Baseball for his conduct in the trade of All-Star pitcher Drew Pomeranz to the Boston Red Sox.
The commissioner's office announced the discipline on Thursday but did not elaborate on what Preller did wrong.
The Padres traded Pomeranz to Boston on July 14 for right-handed prospect Anderson Espinoza.
MLB said it conducted an investigation into the deal, interviewing individuals from both clubs, and submitted the findings to Commissioner Rob Manfred.
