PHOENIX (AP) — Bob Melvin spent most of his Sunday morning introducing himself to all the new faces gathering in the Oakland Athletics’ spring training facility. Next up, he’ll be reading through some of their bios.“When you can converse on a personal level it makes them feel more comfortable,” Melvin said. “It’s to let guys know they will get some personal attention.”Brandon McCarthy is the only returning starter from a rotation that ended last season under Melvin.
