According to major-league sources, Rich Aurilia and Dave Roberts will soon be members of the San Francisco Giants. Aurilia and the Giants are finalizing a two- or three-year contract worth about $3 million per season. The length of the deal still is being negotiated. When asked Friday about an agreement with the Giants, Aurilia's agent, Barry Axelrod, said, "I would say we're very close on that." The Giants and Roberts are zeroing in on a three-year contract valued between $5 million and $6 million a season. A source said Roberts is ready to accept the Giants' offer, and he is awaiting final word from the team.
