What happened: Espinal heads to Reno after playing for the Los Angeles Dodgers earlier this summer. Los Angeles previously designated him for assignment to clear roster space for Tommy Edman.

Why it matters: Espinal gives Arizona experienced infield depth for the stretch run. He made the Dodgers' Opening Day roster and filled multiple positions while teammates were sidelined.

What to watch: Espinal will try to earn a late-season promotion from Reno.
