Matt Kemp continues to struggle at the plate, but the Dodgers insist his health is not an issue.

Kemp struck out four times on Monday, the first time he's done so since 2010. He is in the second year of an eight-year, $160 million deal.

He underwent left shoulder surgery in October to repair damage he sustained when colliding with a wall in Colorado last August.

"I would tell you, internally, that we're all assured that he isn't [hurt], you know? So, he's not," Stan Kasten said in an interview with 710 ESPNLA. "We can't really put our finger on it. We certainly can't blame it on that, because he assures us he's not hurt. The doctors, the trainers have all assured me that he's not hurt, that it's just something he's working through."

Kemp is batting .253 with two home runs and 17 RBIs after 186 at-bats.
