Kershaw returns to DL

Los Angeles Dodgers lefthander Clayton Kershaw returned to the disabled list Friday, this time with a strained lower back.

In his return from a DL stint necessitated by left biceps tendinitis, Kershaw experienced tightness during his five-inning outing against Philadelphia on Thursday.

An MRI exam didn’t reveal any tears, manager Dave Roberts said, but there is inflammation and Kershaw had an injection.

“Don’t think it’s too serious,” Roberts said. “That’s a positive.”

Kershaw, who spent time on the DL in each of the previous two seasons with a back injury, is 1-4 this season with a 2.76 ERA spanning eight starts.
