The Red Sox have told outfielder Cody Ross they want him back for the 2013 season, a baseball source said Saturday, although no talks about an extension have taken place. The Red Sox also want David Ortiz to return, but the sides have yet to speak, the source said. Ross has enjoyed a bounce-back season for the Red Sox after signing a one-year, $3 million deal this winter. He came into Saturday night with a .271/.335/.519/.854 batting line. With the Red Sox having traded outfielder Carl Crawford to the Dodgers, Ross and Jacoby Ellsbury are the only outfielders left from the 25-man Opening-Day roster. Ellsbury is eligible for free agency after the 2013 season, leading to speculation the Red Sox may attempt to trade him this winter, although they have now marshaled the financial resources needed to attempt to sign him to a long-term extension.
