The teams that were in on catcher Russell Martin certainly have some concern about the former All-Star's right hip, which suffered a fracture during last season.
The Red Sox are certainly aware of hip injuries after dealing with Mike Lowell's for a couple of years. It's a relatively new injury in baseball, and most of the time the hip doesn't get better. The Sox stayed in the hunt for Martin, but stopped short. The hip is something to keep an eye on.
Meanwhile, Matt Albers is a pitcher the Sox are considering. He was non-tendered by the Orioles and had a shaky year in 2010 - 5-3, 4.52 ERA, but he's still only 27 and has terrific stuff if someone can get him to harness it. He would be considered for depth and not as a primary reliever.
The Red Sox seem focused on acquiring one righty and one lefty for a middle or setup role. Brian Fuentes, Grant Balfour, Jesse Crain, Matt Guerrier, and Kerry Wood are options.
People have asked me about Joe Blanton. Maybe Sox pitching Curt Young feels comfortable with him, but doesn't seem like a great AL East starter (10-14; 0-3, 8.18 vs. Yankees) . It makes sense if they're flipping him somewhere else or if the team is thinking about dealing Daisuke Matsuzaka.
