(AP) A person familiar with the situation says Arizona has traded outfielder Justin Upton to the Atlanta Braves in a deal that sends All-Star third baseman Martin Prado to the Diamondbacks.
The person spoke to The Associated Press on condition of anonymity Thursday because the trade has not officially been announced.
The Braves also get third baseman Chris Johnson. Atlanta is giving up four minor leaguers in the deal, including top pitching prospect Randy Delgado. The other minor leagues headed to Arizona are right-hander Zeke Spruill, shortstop Nick Ahmed and first baseman Brandon Drury. Prado can become a free agent after this season.
Upton, who has six major league seasons but still is just 25 years old, will join older brother B.J. Upton, who recently signed a free agent contract with Atlanta.
