Last December, the Padres, Rays and Nationals were able to work out the details of a three-team, 11-player trade. The centerpiece of the deal was outfielder Wil Myers, who went from Tampa Bay to San Diego. All the contracts were duly transferred to the proper teams, except for one. On Sunday, it was announced that Washington would be receiving Trea Turner — San Diego’s first-round draft choice, the 13th player selected overall.
