The Marlins set Brad Ziegler free on Tuesday. They needed a controllable arm—Ziegler is in the final year of his contract—while the Diamondbacks needed reinforcements for the bullpen, and boom, the trade was complete.
The veteran sidearmer ends up receiving about $13 million from the Fish (the other $3 million guaranteed by the contract is the responsibility of his new team). Ziegler had a few incredible hot streaks, including this current run that stretches back to June, but overall, his performance slightly disappointed. A 4.36 ERA/4.18 FIP/3.94 xFIP in 106 relief appearances isn’t much different from what would have been expected from a typical Triple-A call-up.
