The Diamondbacks have reportedly struck a deal to bring back veteran right-hander Brad Ziegler before today's trade deadline.
The 38-year-old pitched for the D-Backs from 2011 to 2016. The Diamonbacks will send a relief prospect to the Marlins in return.
Ziegler has been on fire over the last two months, with an ERA of .93. He will hit free agency at season's end.
