The Washington Nationals are the third team and the deal is expected to include 11 players in all, according to Bowman. The Nationals will receive Padres shortstop prospect Trea Turner as a player to be named later and pitching prospect Joe Ross. In addition to Myers, San Diego will receive Rays catcher Ryan Hanigan, plus three other prospects.
Tampa Bay will acquire Nationals outfield prospect Steven Souza and five other prospects.
Myers, 24, was acquired by Tampa Bay in the deal that sent James Shields to the Royals. He won the American League Rookie of the Year in 2013 after hitting .293 with 13 home runs and 53 RBI in 88 games. His numbers dropped to a .222 average with six home runs and 35 RBI in 87 games in 2014.
Turner was chosen No. 13 by the Padres in the 2014 draft and hit .369 with four home runs and 22 RBI in 46 Class A games this year.
Souza had 23 at-bats for the Nationals in 2014, collecting three hits. He played 96 games at Triple-A Syracuse, hitting .350 with 18 home runs and 75 RBI.
Hanigan played 84 games for the Rays last season, hitting .218 with five home runs and 34 RBI.
Myers is the second high profile outfielder the Padres have traded for this winter. Matt Kemp was acquired from the Dodgers last week.
