The announcement, made by Nats president of baseball operations and general manager Mike Rizzo, completes the three-team trade in which Washington received right-hander Joe Ross and a player to be named from the Padres last Dec. 18. The Nationals sent outfielder Steven Souza Jr. and Minor League left-hander Travis Ott to the Tampa Bay Rays as a part of the trade.
Turner was the Padres' first-round pick in 2014 out of North Carolina State University, and due to a rule that didn't allow players to be traded until a year after signing his draft deal, he couldn't officially become a member of the Nationals organization until Sunday.
