CHICAGO -- The D-backs bolstered their middle-infield situation as well as their bullpen just prior to Monday's non-waiver Trade Deadline, acquiring infielder Adam Rosales and right-hander David Hernandez.
The trades cost the D-backs two Minor League right-handers: Jeferson Mejia was sent to the A's for Rosales, while Luis Madero went to the Angels for Hernandez.
Arizona made probably its biggest acquisition almost two weeks ago by picking up outfielder J.D. Martinez from Detroit.
Even after the Martinez trade, the D-backs knew they still wanted to improve their bullpen if they could.
