Diamondbacks' Isaiah Campbell: Lands with Arizona on MiLB deal

The Diamondbacks signed Campbell to a minor-league contract Dec. 5.

In parts of three seasons in the majors, Campbell has collected a 5.65 ERA and 42:16 K:BB over 43 innings. The 28-year-old reliever will give the Diamondbacks some experienced bullpen depth at Triple-A Reno in 2026.
