King (back) will begin a rehab assignment with Double-A Springfield on Wednesday, Derrick Goold of the St. Louis Post-Dispatch reports.

King hasn't been on a big-league mound since late July, as he dealt with an oblique strain and more recently a mid-back strain. It's not clear how many rehab appearances he'll require before being activated from the 15-day injured list, but he's nearing a return.

Scott allowed one hit in a scoreless inning to earn the save in Monday's 3-1 win over the Rockies.

Scott's been in a rough patch lately, allowing four runs over his last 1.2 innings while taking a loss and two blown saves in that span. Despite the struggles, manager Dave Roberts looks to be sticking by his closer, who was able to get the job done Monday for his 21st save in 30 chances this season. Scott is at a 4.47 ERA, 1.21 WHIP and 52:12 K:BB over 50.1 innings on the year, and he remains in control of the closer role, though he could face a threat to his save share when Alex Vesia (oblique) returns Tuesday.

Crismatt allowed four runs on six hits and a walk while striking out three over four innings in a no-decision versus the Giants on Monday.

Crismatt gave up multiple home runs in an appearance for the first time this season. He was limited to 50 pitches (34 strikes) in this ineffective start. The right-hander has posted a 3.24 ERA, 1.40 WHIP and 17:7 K:BB through 25 innings over five outings (four starts). With Anthony DeSclafani back from a thumb injury, Crismatt can ill afford any further poor performances.

Iglesias picked up the save in Monday's 4-1 win over the Cubs, striking out one in a clean ninth inning.

Iglesias submitted his 25th save of the year in his fifth consecutive scoreless outing. The veteran right-hander has rewarded patient fantasy managers while experiencing quite the turnaround from an awful start to the season, which saw him post a 6.75 ERA as of June 5. Iglesias has a 1.51 ERA, 0.64 WHIP and 39:6 K:BB over his last 37 appearances to boost his ERA to 3.62 for the campaign.

Duran worked a scoreless frame, allowing two hits and no walks, to collect the save in Monday's 1-0 win against the Mets. He struck out two.

The flamethrowing righty escaped from a jam in which runners were on second and third with one out, fanning the final two batters he faced. Despite almost blowing this save, Duran has been one of the best relievers in the league since joining Philadelphia at the trade deadline, pitching to a 1.32 ERA, 0.88 WHIP and 17:0 K:BB in 13.2 innings. Overall, the 27-year-old sports a 1.86 ERA, 1.11 WHIP and 70:18 K:BB across 63 total frames with the Phillies and Twins.

Stewart (shoulder) threw a bullpen session Saturday and could face live hitters this week, Sonja Chen of MLB.com reports.

Stewart has been sidelined since Aug. 12 while dealing with right shoulder inflammation, and he has now taken a significant step in his recovery. The right-hander is hopeful that one rehab outing would be enough, and he said Monday that he has felt good since his second cortisone shot in late August.

Vesia (oblique) expects to be activated from the 15-day injured list before Tuesday's game against the Rockies, David Vassegh of AM 570 LA Sports reports.

Vesia hasn't appeared in a big-league game since Aug. 21 while on the mend from a right oblique strain, but all has gone well while on a rehab assignment. He should immediately slot back in as a high-leverage arm for the Dodgers upon his return from the shelf.

The Cubs recalled Roberts from Triple-A Iowa on Monday.

Roberts will rejoin the Cubs and provide a fresh arm in the bullpen after Daniel Palencia (shoulder) was placed on the 15-day injured list in a corresponding move. Over 10 appearances with the big club this season, Roberts has posted a 6.00 ERA and 1.33 WHIP across nine innings.

Ortega (elbow) struck out one batter and surrendered two earned runs on one hit and two walks over one inning in his season debut for Triple-A Syracuse on Sunday after being reinstated from the 7-day injured list.

After requiring surgery last summer to remove a bone spur from his right elbow, Ortega signed a minor-league deal with the Mets over the winter but had remained on the shelf all season while completing his recovery from the procedure. He finally made his debut for the Triple-A club Sunday, which came after he completed an eight-appearance rehab assignment with Single-A St. Lucie. Ortega will look to finish the season on a high note with the hope of securing a minor-league deal with the Mets or another organization during the upcoming offseason.

Keller appears to be the likeliest candidate to take over as the Cubs' closer after Daniel Palencia (shoulder) was placed on the 15-day injured list Monday, Bruce Levine of 670TheScore.com reports.

Palencia's availability for the remainder of the season is in jeopardy while he recovers from a right shoulder strain. Keller has been a revelation out of the Cubs bullpen this season and has yet to permit a run over 20 second-half appearances, yielding a total of just three hits over that stretch. If manager Craig Counsell prefers to take a committee approach at closer while Palencia is out, Andrew Kittredge and Caleb Thielbar could also be in the mix for saves along with Keller.
