Also going to Atlanta is third baseman Chris Johnson, who will likely platoon with Juan Francisco at the hot corner. The D-backs get Prado, 22-year-old righty Randall Delgado and three more prospects.
It's undoubtedly a coup for Atlanta. It creates an outfield of Jason Heyward in right, B.J. Upton in center and Justin Upton in left. All are fast, all have impressive power, all have strong arms, all strike out a lot. It's the best outfield in the National League and probably the second best in the game to the Angels.
By losing Prado -- which was a bit surprising -- Atlanta doesn't get a huge short-term upgrade in this deal. Prado was worth nearly 6.0 WAR last season and has averaged 3.9 the last three years, compared to Johnson's 1.25 average in two full seasons. But Justin Upton is a four-win player himself, and the previous left field option for Atlanta was a platoon of Reed Johnson and Prado, with Francisco playing third in games Prado plays left.
This trade pushes the Phillies further back in the NL East. We wrote in this space last week that Atlanta's lineup was even with the Phils', but that changes now. That entire outfield is either in its prime or entering it, and all are controlled for at least three more years.
That is perhaps the most appealing aspect with Justin Upton, who for some strange reason the Diamondbacks have been on a quest to trade for two years. He is under contract through the end of 2015 at just $38.5 million.
But hey, at least the Phillies have Delmon Young.
