 Quentin was hitting .290 with 30 doubles, three triples, nine homers and 52 RBIs in 85 games for the Tucson Sidewinders when he was called up to the Diamondbacks on July 20, 2006; after grounding out in his first two major league at bats, Quentin hit a two-run home run off Mark Hendrickson in the sixth inning of Arizona's 5–2 win over the Los Angeles Dodgers.His arrival was long anticipated by Diamondbacks fans; he was expected to replace Shawn Green as the everyday right fielder for the Diamondbacks once Green retired or otherwise left the team.Green was traded to the New York Mets in August, clearing the way for Quentin to become a full-time starter.
