The Red Sox would love to add Carlos Beltran via a trade with the Mets, but they are wary of paying the price to acquire the outfielder, according to a team source. New York is seeking top-tier prospects in a trade for Beltran. Boston also believes that they have more pressing needs with three-fifths of their starting rotation out and reliever Bobby Jenks on the disabled list. "We're interested in Beltran, but the price would have to be sensible," a Red Sox source said. "We lost a lot of good prospects for (Adrian) Gonzalez and want to protect our better minor leaguers."
