After winning the National League West Division crown in the 2011 season, the Arizona Diamondbacks fell to a .500 finish in each of the next two seasons.
Arizona further collapsed to a 64-98 finish in 2014. However, the club bounced back in 2015, picking up 15 wins to finish within four games of the .500 mark at 79-83.
Diamondbacks management felt that the club was coming on, and so a couple of key moves were made with an eye towards contending for at least a 2016 NL Wildcard berth.
At the Winter Meetings in December of 2015, the team signed free agent ace right-hander Zack Greinke. A day later they dealt an extremely valuable package of prospects led by shortstop Dansby Swanson to the Atlanta Braves in order to land pitcher Shelby Miller. Then in January they traded with the Milwaukee Brewers for shortstop Jean Segura.
Adding these players to a lineup that was led by the 2015 NL MVP runner-up Paul Goldschmidt and rotation with emerging young talents such as Patrick Corbin and Robbie Ray, Arizona believed they would indeed contend for a postseason berth.
Instead, the Diamondbacks collapsed back to a 69-93 record, 18 games off that NL Wildcard pace and 22 games behind the division-winning Los Angeles Dodgers.
Key injuries decimated the lineup, as a pair of starting outfielders, A.J. Pollock and David Peralta, missed most of the season.
WHAT WAS EXPECTED OF THE 2016 ROTATION
However, it was the collapse of the starting rotation, in particular the failures of the two big acquisitions in Greinke and Miller, that led to the team collapse.
