"I think he's fine to go deep [into a game], depending on how he's throwing," Roberts said. "It's great and I'm happy for Clayton [that he's] feeling healthy. Performing is one thing, but if he feels healthy and strong, we'll bet on the performance. We're playing better baseball -- and to add him to the mix, it's a real good thing for all of us.
"It's a big lift. You've got your ace coming back and we've kind of righted the ship a little bit, trending in the right direction. You can compare it to having [Justin Turner] back on the position-player front."
The Dodgers opened the season 16-24 without Turner, who suffered a fractured left wrist in Spring Training. They are 7-4 since his return. Since Kershaw went on the disabled list on May 6, the Dodgers are 8-10.
Kershaw figures to bump Brock Stewart from the starting rotation. Roberts was non-committal on whether Stewart would be shifted into a bullpen role in the Major Leagues or return to the Minor Leagues and continue starting so he'll be stretched out when the Dodgers need a starter again. Stewart will start for the Dodgers on Monday.
