Even with an early-season acquisition of Cliff Pennington, the Diamondbacks' biggest need remained finding a shortstop for the present and future.
The Diamondbacks found their man in Cincinnati Reds shortstop Didi Gregorius, as they acquired him in a three-team trade that also involved the Indians.
In total, the deal cost Arizona top pitching prospect Trevor Bauer and relievers Matt Albers and Bryan Shaw. Along with Gregorius, the team acquired reliever Tony Sipp and first base prospect Lars Anderson.
With Ian Kennedy, Brandon McCarthy, Trevor Cahill, Wade Miley, Tyler Skaggs, Josh Collmenter, Pat Corbin and Daniel Hudson, the D-Backs already have plenty of options for their rotation.
However, as one of the top pitching prospects in all of baseball, Bauer could easily make Arizona regret its decision to move him with a breakout season in Cleveland.
