Jon Paul Morosi of FOXSports.com reports that free agent Darren Oliver is drawing interest from the Rangers, Angels, Red Sox, and Blue Jays. Oliver returning to the Rangers once looked like a forgone conclusion, but ESPN's Jerry Crasnick reported over the weekend that he is now "keeping an open mind" about where he'll play next season. The 41-year-old left-hander earned $3.25 million in 2011 while posting a career-low 2.29 ERA in 61 relief appearances.
