The Braves made it clear they were willing to move Miller this winter and it appeared the organization was hoping to add outfield depth in return. The Diamondbacks, Cubs, Orioles and Dodgers were all linked to Miller before he was ultimately traded.

Miller is the second notable arm to be added the Diamondbacks' rotation this winter after the club agreed to sign free agent Zack Greinke on Friday. Arizona was known to be seeking front of the rotation arms and was able to add a pair of experienced starters.

Miller, 25, pitched to a 3.02 ERA and 3.45 FIP over 205.1 innings with the Braves last season. He has proven to be durable and is still a relatively affordable starting option.

The haul that the Braves received for Miller is being regarded as an extremely strong one. It includes Inciarte (a proven major-league outfielder) Blair (a top pitching prospect), and Swanson (the top overall pick from June's draft)

In addition to Miller, the Diamondbacks get a quality pitching prospect in Speier. At just 20, he pitched to a 2.86 ERA and 2.65 FIP over 44.0 innings in Single-A. The Tigers traded Speier, a seventh round pick by the Red Sox in 2013, to the Braves in the Cameron Maybin deal. Now, Speier will be pitching in Arizona's farm system.

Inciarte, 25, had a notable amount of success in Arizona last season, batting .303/.338/.408 to complement six home runs and 45 RBIs. He will likely immediately enter Atlanta's outfield mix heading into 2016. Inciarte's speed has also proven to be valuable on the base paths, and he stole 21 bases last season and 19 in 2014.

Swanson, 21, batted .289 last season in Single-A and was the No.1 overall pick in the 2015 draft. He gives the Braves a talented young shortstop after the organization decided to trade Andrelton Simmons to the Angels in November. MLB.com ranked Swanson the tenth best prospect in baseball at the end of the regular season. Most see him as a potential number two hitter, and some scouts expect him to be in the majors by 2018.

Blair, 23, pitched to a 3.16 ERA over 77.0 innings in Triple-A after beginning the year in Double-A. Baseball America ranked him the second best prospect in Arizona's minor league system. Blair is projected to be a middle of the rotation starter and could be ready to make his major league debut as soon as 2016.

Atlanta first acquired Miller from the Cardinals last season in exchange for Jason Heyward.
