The Red Sox made an unsuccessful attempt to acquire left-hander Chris Capuano from the Mets this week, according to a league source. Boston wanted Capuano to start against the Yankees on Sunday in New York. The deal is "dead," according to the source. The Mets treated the inquiry from the Red Sox serious enough that they held back Miguel Batista the first day of the series in St. Louis and did not use him in relief in case he needed to be a spot starter Thursday in place of Capuano.
