The Arizona Diamondbacks have added another All-Star to their rotation by acquiring Shelby Miller from the Atlanta Braves as part of a five-player trade, it was announced Wednesday.
Arizona will send a three-player package highlighted by shortstop prospect Dansby Swanson, the No. 1 overall pick in this year's draft, to Atlanta in exchange for Miller. The Braves also will receive outfielder Ender Inciarte and pitching prospect Aaron Blair, while the Diamondbacks will also receive minor league pitcher Gabe Speier.
The Braves had previously insisted that Arizona include A.J. Pollock in any potential deal for Miller, but the star outfielder was not a part of the trade, which was agreed to Tuesday night.
Sources told ESPN earlier Tuesday that the Diamondbacks were closing in on a deal with free-agent right-hander Mike Leake. But a source told ESPN's Jerry Crasnick that Arizona's interest in Leake effectively ended with the Diamondbacks' acquisition of Miller.
Miller, who went 6-17 last season despite posting a career-best 3.02 ERA, will join Cy Young runner-up Zack Greinke atop Arizona's rotation. The Diamondbacks and Greinke finalized a six-year deal earlier Tuesday that, according to sources, is worth $206 million.
"Our ownership stepped up in allowing us to get Zack Greinke," Diamondbacks GM Dave Stewart said Wednesday. "It puts us in a position to get better as a team, but we weren't complete. We needed an additional piece to our rotation.
"We've got Goldy [Paul Goldschmidt] and we've got Pollock, our core group of guys, who last year really put on a good display of baseball. And quite frankly we think that it's time to try to take it to the next level."
Grienke and Miller should be followed in the rotation by Patrick Corbin, Rubby De La Rosa and Robbie Ray.
"You're getting almost 800 innings out of your starting rotation, which should help our bullpen out,'' Stewart said. "The biggest part of our problems in our pen last year is we had to go there very often and ask them for a lot of innings.''
Miller, 25, spent one season with the Braves after playing for the St. Louis Cardinals from 2012 to 2014. He had a 24-start winless streak in 2015 but also posted career bests in innings pitched (205⅓) and strikeouts (171).
"This was another trade that will brighten our future and give us impact-type players not only tomorrow but right now," Braves president John Hart said in a statement. "We feel each of the guys we got back has impact-level talent along with a tremendous make-up."
Swanson, 21, was selected with the top overall pick June 8 after leading Vanderbilt to the College World Series, in which the Commodores lost to Virginia in the championship. Swanson played 22 games at Class A Hillsboro and batted .289 with one home run in 83 at-bats. He becomes the fourth No. 1 overall pick in MLB history to be traded by his drafting team before reaching the majors.
Inciarte, 24, batted .303 last season and could have a spot as Atlanta's leadoff hitter. He had six homers, 21 stolen bases and 73 runs scored in 132 games in 2015.
I want to take a moment to thank the @Dbacks organization and the Fans for having me around for a couple fun years.

"I value the draft picks just as much as other ballclubs," Stewart said. "I think the difference is if my gut tells me to do something then I follow my gut. Believe me, they're very highly regarded players, but three players do not make our future.''
Atlanta got Speier from Detroit in the trade for Cameron Maybin last month. The 20-year-old Speier has a 2.34 ERA in 45 games -- eight starts -- over three minor league seasons. He made 33 appearances for Class-A West Michigan this season.
