A home for today's random Twitter rumors…

• The Red Sox might not activate Mike Lowell today because they're trying to trade him, tweets Nick Cafardo of the Boston Globe.
• The Marlins are getting tons of calls on Cody Ross but aren't inclined to move him, tweets Juan C. Rodriguez of the South Florida Sun-Sentinel.  ESPN's Jayson Stark says the Marlins are wavering on their stance not to deal Ross, and the Braves are making a push. 
• The Sox made a run at the Cubs' Sean Marshall and were shot down, tweets ESPN's Jayson Stark.  Marshall is having a dominant year out of the Cubs' pen.

• Action has been light on Octavio Dotel so far, tweets Morosi.
• The Diamondbacks aren't sure about trading Aaron Heilman, reports Ken Rosenthal, but could move Chad Qualls and Adam LaRoche.  SI's Jon Heyman says the D'Backs have gotten nibbles on Qualls but nothing is close yet.
• The Indians are getting "significant hits" on Jake Westbrook, says ESPN's Buster Olney.  The Cardinals and Yankees have checked in, reports Stark.
