Rays' Javy Guerra: DFA'd by Tampa Bay

Tampa Bay designated Guerra for assignment Sunday, Neil Solondz of the Rays Radio Network reports.

The Rays will replace Guerra on the 40-man roster and in the big-league bullpen with Robert Dugger, whose contract was selected from Triple-A Durham in a corresponding move. After being acquired from the Padres on April 16, Guerra appeared in six games and gave up five earned runs on eight hits and a walk over 5.1 innings.
