PHILADELPHIA -- Mookie Betts was scratched from the Dodgers' lineup Tuesday, and a trip to the injured list could be coming for the star outfielder.

Betts continues to be bothered by the right hip injury that has been an issue for most of the second half. He came in on Monday’s off-day and reported soreness, leading to Tuesday’s scratch.

“Just achy, sore; basically can't play,” manager Dave Roberts said. “I don't know what other tests we're going to do, but to envision an IL happening, it's very probable. ... I’m frustrated for Mookie, because he wants to go out there and he can't physically do it.”

The Dodgers called the injury “inflammation” when Betts landed on the IL last month, but a cortisone injection has not resolved the problem. Roberts said “everything is on the table right now” when asked if another shot was a possibility, though the manager added that surgery does not appear to be an option at the moment, though it could become one after the season.

“I think that as we go forward, get through the season, I'm sure that will be discussed,” Roberts said. “I don't think anyone knows what type of surgery that would require.”

Betts appeared in three games after the All-Star break before landing on the IL from July 20-31. He returned on Aug. 1 and played five games, but he was given the day off against the Angels on Sunday.

Should Betts land on the IL and eventually return, Roberts believes the hip issue will be one the Dodgers will have to be wary of for the remainder of the season.

“We've given it days, and it almost seems like when he comes off the off-day, it's worse,” Roberts said. “I think everything's on the table right now. We're having conversations, tests, and I think we'll know more later."

Third option

Gavin Lux will begin playing more third base during his Minor League rehab assignment, giving the Dodgers another potential option if Justin Turner’s groin injury becomes more troublesome.

“If you look at it, third base is essentially a hybrid second baseman,” Roberts said. “You could argue that you're playing more second base than third base. The third baseman plays a lot of times -- especially with the right-handed starter -- [as much] on the other side of the bag as they do at third base.”

Lux is on the IL with a left hamstring injury, and with Trea Turner now occupying second base, Lux’s place on the roster isn’t as clear-cut if he’s unable to play multiple positions.

“It's another option; Gavin understands the landscape of the roster,” Roberts said. “We all know that he could still be a viable piece, but certainly having him be able to move around the diamond helps his case.”

See you in September

Clayton Kershaw (left forearm inflammation) and Danny Duffy (left flexor strain) were moved to the 60-day IL on Monday, pushing the return for both pitchers into September.

Kershaw did not accompany the Dodgers on their East Coast trip, as Roberts said this process “has been taxing in every way” for the left-hander.

“Our encouragement was for him to get home, spend time with the family, recharge and we'll see him when we get back,” Roberts said.

The decision to move Duffy -- who was acquired before the Trade Deadline -- to the 60-day IL had more to do with his timeline than any setback in his rehab.

“With the timing of when he'd come back, it just seemed like it made more sense,” Roberts said of Duffy, who will be eligible to return in mid-September. “Once we do get to that date, he should be ready to go.”

When Duffy returns, it remains to be seen whether he will be built up enough to start, which Roberts said remains the goal. If not, the manager said he could see Duffy being a “two- or three-inning monster” out of the bullpen.
