Red Sox Notes: Varitek, Oswalt, Saunders

The Red Sox sent Jed Lowrie and Kyle Weiland to Houston for Mark Melancon today before agreeing to terms with Nick Punto on a two-year deal. One thing they did not do was bid on Yu Darvish. Here’s the latest from Boston (and for more on the Red Sox, click here):

• Jason Varitek may still be in the picture for the Red Sox, according to Nick Cafardo of the Boston Globe (on Twitter). It still seems hard to envision a deal between Varitek and the Red Sox, who have catchers Jarrod Saltalamacchia, Kelly Shoppach, Ryan Lavarnway and Luis Exposito.
• The Red Sox maintain interest in Roy Oswalt, according to Jon Paul Morosi of FOX Sports (on Twitter). 
• Joe Saunders is Boston's next target, according to Jim Bowden of MLB Network Radio (Twitter link).
