D-backs opening 3-game set against padres

Posted: Updated:

PHOENIX -- If the Diamondbacks are to gain sole possession of first place in the NL West, they'll need to show some improvement at home.

A series against the last-place San Diego Padres should help.

The D-backs open a three-game set with the Padres tonight at Chase Field.
