The Rays have designated lefty Dana Eveland for assignment, as Chris Cotillo of SB Nation first tweeted. The club has selected the contract of outfielder Jaff Decker to take his spot on the active roster, as Marc Topkin of the Tampa Bay Times reported earlier on Twitter.

Eveland, 32, had struggled to a 7.56 ERA in his 16 2/3 innings on the year. He has averaged better than a strikeout per innings, but his swinging strike rate is down and he has also issued 13 free passes in that span.

Decker will get another shot at the majors after brief stints in each of the past three years. He may be needed to help cover for Steven Souza, who suffered a hip injury last night. Decker owns a .233/.351/.358 batting line over 232 Triple-A plate appearances on the year.
