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.
Up next: The Cubs face another lefty when they return home on Monday to face the New York Mets. Travis Wood (1-3, 4.14) will start for the Cubs against the Mets’ Johan Santana (5-3, 3.00).
