If Adrian Beltre rejects Seattle's arbitration offer, Boston could scoop him up as a free agent. "It wouldn't be surprising if Beltre falls in the Red Sox's lap if he doesn't accept arbit from the Mariners," Bob Nightengale of USA Today wrote on his Twitter page. Red Sox manager Terry Francona has said he's content with Mike Lowell at third, but the team has been linked to a number of corner infielders.
