Manager Dave Roberts said Treinen (shoulder) threw a "normal" bullpen session Wednesday and could soon face live batters, Fabian Ardaya of The Athletic reports.

EDGE Analysis

Treinen was activated from the injured list Sept. 2 but returned to the shelf with shoulder tightness after only two outings, but he's quickly been able to resume mound work. The right-hander will be eligible to return from the IL late next week and may not require a rehab assignment given the expected brevity of his absence.

Treinen (shoulder) played catch Sunday and expressed optimism that he'll be ready to return from the 15-day injured list prior to the postseason, Jack Harris of the Los Angeles Times reports.

EDGE Analysis

Treinen was shelved in late April with right shoulder discomfort and missed more than four months before being activated Sept. 2, only to land on the IL one week later following two relief appearances with the Dodgers. On a positive note, Treinen's latest setback with his shoulder doesn't appear to be a major concern, as the Dodgers haven't shut him down from throwing. He'll work on strengthening the shoulder over the next week or so before potentially making his way back from the IL shortly before the regular season ends Oct. 5.

Treinen was placed on the injured list with right shoulder tightness Saturday, Fabian Ardaya of The Athletic reports.

EDGE Analysis

Shoulder issues have limited Treinen to just five appearances this season. While he returned from the injured list eight days ago, injury troubles quickly resurfaced. No timeline for his return this time around has been offered, but it's likely that the Dodgers will care more about maximizing his chances of pitching in the playoffs over getting him back as soon as possible. Andre Jackson was recalled to take his place in the bullpen.

Treinen (arm) didn't feel right after playing catch Saturday and could return to the injured list, David Vassegh of AM 570 LA Sports reports.

EDGE Analysis

Shoulder troubles sidelined Treinen from mid-April through early September. While he's thrown a pair of scoreless innings since his return to action, his arm issues have resurfaced. Whether or not a potential trip to the injured list would be brief or season-ending remains to be seen.

Treinen was unavailable Friday against the Padres due to arm soreness, Fabian Ardaya of The Athletic reports.

EDGE Analysis

Treinen has been effective over two appearances since returning to action, allowing no hits and a walk while striking out one in two scoreless innings over two outings. However, he hasn't pitched since Monday and has apparently been down with an arm issue. Manager Dave Roberts didn't sound too concerned about the injury, so Treinen should be considered day-to-day.

Treinen needed only five pitches to complete a perfect inning against the Padres on Saturday.

EDGE Analysis

Treinen was activated by Los Angeles on Friday and made his first big-league appearance since April 14 the following day. The right-hander made things look easy, retiring all three batters he faced on a combined five pitches. This wasn't a high-leverage situation, but Treinen figures to see plenty of those down the stretch.

Treinen (shoulder) was reinstated from the 60-day injured list Friday.

EDGE Analysis

Treinen spent the last few weeks in the minors on a rehab assignment and posted a 4.50 ERA and 1.50 WHIP in six innings over seven relief appearances with the Triple-A club. The right-hander was targeting a Sept. 2 return, and he was able to meet that timetable following his lengthy rehab process. Treinen will likely serve as a setup man for the Dodgers down the stretch, but it's possible that the team chooses to ease him back into action with a few lower-leverage outings in the near future.

Treinen (shoulder) is expected to make his final rehab appearance for Triple-A Oklahoma City on Tuesday before being reinstated from the 60-day injured list Friday, Juan Toribio of MLB.com reports.

EDGE Analysis

When Treinen began his rehab assignment Aug. 12, the Dodgers identified Sept. 2 as the target date for the right-hander's return to the active roster, and that timeline hasn't changed in the proceeding three weeks. Treinen has performed satisfactorily through his first six rehab outings at Oklahoma City -- he's posted a 3.60 ERA, 1.40 WHIP and 6:1 K:BB in five innings -- and if he comes out of Tuesday's appearance unscathed, he'll give the Dodgers bullpen yet another potential impact arm heading into the postseason. While Craig Kimbrel seems to have lost some security as the Dodgers' closer, high-performing setup men Evan Phillips and Brusdar Graterol will likely be ahead of Treinen in the pecking order for saves if manager Dave Roberts elects to make a change at the back of the bullpen.

Dodgers manager Dave Roberts suggested Sunday that Treinen (shoulder) is on track to return from the 60-day injured list Sept. 2, Matthew Moreno of DodgerBlue.com reports.

EDGE Analysis

Though Treinen didn't make his third rehab appearance at Triple-A Oklahoma City on Saturday like the Dodgers had planned, Roberts suggested it wasn't the result of any physical setback. Treinen will take the next two weeks to get ramped up in the minors before rejoining the big club for the final month of the season. The 34-year-old right-hander will likely settle into a setup role in front of closer Craig Kimbrel.

Treinen (shoulder) struck out one batter in a perfect inning for Triple-A Oklahoma City on Friday.

EDGE Analysis

This was Treinen's first game action since April 14, and he needed just nine pitches to make it through an easy inning. According to Fabian Ardaya of The Athletic, the right-hander was at 95-96 mph on the radar gun. Treinen will likely need to make at least a few more rehab appearances before returning to the Dodgers.
