The Arizona Diamondbacks might be done with one of their biggest playoff-affecting series of the season, after splitting their four-game series with the San Diego Padres at Chase Field. But the tough opponents don't stop there; they get even tougher, in the form of the NL West-leading Los Angeles Dodgers.In fact, the Diamondbacks might be, arguably, catching the Dodgers at the worst possible time. Los Angeles has lost six straight games. They were swept out of their own stadium by the Diamondbacks ahead of the All-Star Break. And they just had an off day Thursday, something Arizona has not been afforded since July 30. With the amount of talent — old and new — on LA's roster, the Diamondbacks could find themselves in the crossfires of a motivated, still-potent Dodger club.Diamondbacks stare down tough Dodger challengeJun 2, 2026; Phoenix, Arizona, USA; Arizona Diamondbacks outfielder Corbin Carroll against the Los Angeles Dodgers at Chase Field.
