The Rays designated Russ Canzler for assignment, Marc Topkin of the Tampa Bay Times tweets. The move creates 40-man roster space for Jeff Keppinger, whose deal with the Rays became official today.
Canzler, 25, made his MLB debut in 2011, appearing in three games with the Rays as a September callup. He spent most of the season at Triple-A, where he posted a .314/.401/.530 line with 18 home runs and 40 doubles in 549 plate appearances. The Cubs selected Canzler in the 30th round of the 2004 draft.
