Arizona manager Bob Melvin told Luis Gonzalez he was going to start rookie Carlos Quentin in left field Thursday night to give him a night off against a tough left-hander. Gonzalez took it a different way. The 16-year veteran interpreted his benching as a sign the organization may be ready to part company with him at year's end. There has been speculation the club will not pick up its $10 million option on Gonzalez for 2007.
