From Marc Topkin of the Tampa Bay Times comes word that the Rays have designated right-handed reliever Heath Bell for assignment, clearing a 40-man roster spot for the promotion of Nate Karns.
Bell had surrendered 24 hits, eight walks, and 16 runs — 14 earned — in 17 1/3 innings this year for the Rays, who got him from the Diamondbacks this past winter as part of a three-team trade.
The 36-year-old owns a rough 4.91 ERA and 1.507 WHIP in 146 2/3 innings since signing a three-year, $27 million free agent contract with the Marlins prior to the 2012 campaign. That deal ends this fall.
Bell will either be traded, released, or outrighted to Triple-A Durham within the next 10 days.
