PHOENIX (AP) — Arizona has traded outfielder Justin Upton to the Atlanta Braves in a seven-player deal that sends former All-Star infielder Martin Prado to the Diamondbacks.

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 leaguers headed to Arizona are right-hander Zeke Spruill, shortstop Nick Ahmed and first baseman Brandon Drury. Prado, projected to play third base for the Diamondbacks, can become a free agent after this season.

Upton, who has five-plus 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. The younger Upton, who has three years and $38.5 million left on his contract, had been the subject of trade speculation throughout the offseason and vetoed a trade to the Seattle Mariners.

Prado, who joins fellow Venezuelan Miguel Montero in Arizona, made the All-Star team in 2010 as a second baseman and played mostly in left field last season. A versatile infielder, Prado was projected to move to third base for the Braves this season to replace the retired Chipper Jones.

Diamondbacks President Derrick Hall said via Twitter that the team wants to sign Prado to a long-term deal.

"This is the type of player we want in our lineup," he wrote.

The Braves didn't re-sign centerfielder and leadoff hitter Michael Bourn and Prado, the No. 2 hitter behind Bourn, had been a candidate to hit leadoff. Shortstop Andrelton Simmons now is expected to assume that role. Simmons hit .289 with a .335 on-base percentage in 49 games as a rookie last season.
