Rays' Justin O'Conner: Healthy, assigned to Double-A

O'Conner (back) is healthy and was assigned to Double-A Montgomery on Tuesday, the Tampa Bay Times' Marc Topkin reports.

A back injury limited him to 20 games last season, so he will head back to Double-A, where he has 136 games under his belt, to knock the rust off before heading to Triple-A Durham. O'Conner has an elite arm behind the dish and some raw power, but he has hardly ever hit in the minors, and profiles at best as a glove-first catcher in the big leagues.
