Zach Eflin heads to injured list as Brandon Lowe returns for Rays

Zach Eflin felt the tweak in his back as soon as he threw the pitch near the end of his outing against the Blue Jays on Saturday. Now, inflammation in his lower back has landed the right-hander on the 15-day injured list. Eflin was the first of several roster moves the Rays made before the series opener against the Red Sox at Tropicana Field. Brandon Lowe (oblique strain) was activated, as was left-handed reliever Richard Lovelady, who the Rays acquired from the Cubs over the weekend.
