The Red Sox remain interested in Washington Nationals right-hander Chad Cordero, who went 7-4 with 29 saves in 33 opportunities last season, but is currently unwilling to part with a top pitching prospect. The Nationals have interest in Craig Hansen and right-hander Michael Bowden (9-6, 3.51 ERA in 24 starts at Single-A Greenville) but are mostly focused on Clay Buchholz, who the Sox have refused to deal.
