LOS ANGELES -- Thomas Stripling 's move back to the bullpen will have to wait another week as the right-hander was placed on the 10-day disabled list on Wednesday with lower back inflammation.

The roster vacancy allowed the Dodgers to recall left-hander Hyun-Jin Ryu from the DL. Ryu started Wednesday's series finale against the Giants, his first game in the rotation since May 2. Stripling's DL move was retroactive to Sunday.

Stripling made his first National League All-Star team in July after he thrived as a fill-in starter. The Dodgers had four of the five starters in their Opening Day rotation on the disabled list at one point, and Stripling was vital in helping the team turn around from a slow start.

From May 6-June 26, Stripling made 10 starts and went 6-1 with a 1.86 ERA. In back-to-back starts at the end of July, though, he gave up a combined nine runs in 8 2/3 innings. Stripling went to the DL for a foot issue in late July before making a start on Aug. 9, when he gave up one run over six innings at Colorado.

But with Alex Wood and Ryu set to rejoin the rotation this week, the intiial plan was to move Stripling back to the bullpen, where he started the season. Wednesday's move delayed that.

"I don't have any bulging discs or anything like that, it's basically managing symptoms," Stripling said. "Give it a couple of days, get on some good meds and try to get the inflammation out of there. I'm going to give it through the weekend, since they are going to Seattle, and I'll stay here."

Stripling said he will likely play catch while the team is away, then ramp up more baseball activity next week.

"This [back injury] kind of crept up on me, which kind of stinks," said Stripling, who added that a soft bed in the team's hotel in Denver might have been a contributor to the issue. "Yeah, I'm kind of frustrated to be a guy they counted on when things got hectic earlier in the season, to then be a guy who is all over the place with both health and where I am pitching-wise."

Jansen throws again

Dodgers closer Kenley Jansen threw his second bullpen session since going on the disabled list over the weekend because of an irregular heartbeat. Joc Pederson and Chase Utley took simulated at-bats during the session.

Manager Dave Roberts said everything went well, but that the team is still waiting for a follow-up exam on Monday before a timetable for Jansen's return can potentially be made.

"As far as the medical side, I don't know too much of, but I do know that Kenley feels good," Roberts said. "We want to keep him away from a baseball or something hitting him for any type of trauma, and we're just waiting for the 20th."

Relief help coming

Roberts expects right-hander Daniel Hudson to come off the disabled list Friday when the team opens a three-game Interleague series at Seattle. Hudson, who pitched a simulated game Monday, has been on the DL with right forearm tightness.
