The Arizona Diamondbacks have acquired right-handed reliever Brad Ziegler from the Oakland Athletics in exchange for left-handed reliever Jordan Norberto and first baseman Brandon Allen.

Ziegler, 31, was 3-2 with a 2.39 ERA and 1.35 WHIP in 43 appearances for the A’s this year. He is one of the rare sidearmers in baseball, and right-handed hitters are batting just .198 against him as compared to .396 against left-handed hitters. He will fit in nicely as a situational righty for D-backs manager Kirk Gibson.

The Athletics acquire a big arm in Norberto. Norberto, 24, throws 94-95 mph with a solid-to-average breaking ball. He has above-average stuff, and now it’s a question of whether he can command it. Over the past two months, his command has improved, and the A’s feel he is heading in the right direction. He’s also a 0-3 service-time player with options, giving the A’s payroll and roster flexibility as they wait for the production to catch up with the electric stuff.
