How it happened: Matt Garza allowed three runs on five hits in seven innings and got little support from his offense. Alfonso Soriano drove in the lone run for the Cubs with a solo homer in the seventh inning. Diamondbacks starter Wade Miley allowed just three hits in his eight innings to get the win.
What it means: The Diamondbacks swept the Cubs, who fell to 6-16 in June.
Outside the box: The Cubs have won just three of their 19 games against left-handed starters for the majors' worst mark.
