What happened: Longtime Diamondbacks observers told Bob Nightengale they could not recall a player being booed so loudly while coming to the plate. Marte was jeered again after grounding out in his return to the lineup.

Why it matters: The reaction puts a public strain on Marte's return after he acknowledged letting teammates down following his absence. Arizona enters September with its playoff push underway.

What to watch: Watch whether the reception changes during the Diamondbacks' remaining home games and how Marte responds at the plate.
