Infielder Trea Turner, who had been a top prospect in the San Diego Padres organization, is finally joining the Washington Nationals after being initially traded to the team in December 2014. ESPN.com was one of the first to report the development, which also was confirmed by the official Twitter accounts of the Nationals and Yahoo Sports.

Turner was the No. 13 overall pick by the Padres in the 2014 MLB Draft and was part of a three-team trade involving the Padres and Tampa Bay Rays in December that same year but had to wait for a few months to join the Nationals because of league rules prohibiting draft picks to be traded within a year. Another MLB rule states that teams have six months from the time of the trade for a deal to be finalized.

"From the outset, this was a complex deal, but we thought it was one that would better our organization for the present as well as the long term," Nationals general manager Mike Rizzo said via ESPN.

Turner also took to Twitter to thank the Padres and admitted being excited to join the Nationals.

The Nationals are currently second in the East Division of the National League with 33 wins against 30 losses so far this season.
