Kittredge picked up the save Wednesday against Atlanta, striking out one in a clean ninth inning.

It's notable that Kittredge saw Chicago's first save opportunity since closer Daniel Palencia (shoulder) landed on the injured list. That usage would appear to put him first in line for future save chances, though it's certainly still possible that manager Craig Counsell has a committee approach in mind for his closer position for the time being. Kittredge is worth a speculative add in most fantasy formats as this situation unfolds -- the veteran right-hander owns a 3.45 ERA, 1.00 WHIP and 52:10 K:BB through 47 innings on the season.

The Nationals optioned Ribalta to Triple-A Rochester on Wednesday.

Since being promoted into Washington's bullpen Aug. 1, Ribalta has turned in a 5.27 ERA and 1.90 WHIP alongside a 15:11 K:BB across 13.2 innings. The 27-year-old's subpar performance will now cause him to return to the minors in anticipation of MacKenzie Gore's (shoulder) return from the injured list Thursday.

Seymour (1-3) took the loss Wednesday against the Diamondbacks, allowing four runs on six hits across 1.1 innings. He struck out one.

It was a rough day for Seymour, who gave up a home run to Geraldo Perdomo to lead off the game before giving up three more runs before departing with one out in the second. The 26-year-old Seymour has given up nine runs across 9.1 innings in three starts with the Giants. He's currently scheduled to face the Diamondbacks again in his next outing, though he could return to the bullpen when Carson Whisenhunt (back) is able to rejoin the rotation.

The Cubs optioned Roberts to Triple-A Iowa on Wednesday, Maddie Lee of the Chicago Sun-Times reports.

Roberts' stay with the big club lasted just two days, and the right-hander didn't appear in relief in either of the Cubs' first two games of their series in Atlanta. He'll be pushed off the 28-man active roster with the Cubs bringing back Jameson Taillon (groin) from the 15-day injured list to start Wednesday's series finale.

Miller is hopeful of avoiding a full UCL repair of his right elbow following a visit with Dr. Keith Meister in Texas, Adam McCalvy of MLB.com reports.

Miller needs surgery, but a procedure that's less invasive than Tommy John surgery would give him a chance to return late in the 2026 season. The reliever collected a 2.74 ERA and 54:15 K:BB over 46 innings between the Diamondbacks and Brewers this season and will be a free agent this winter.

Santana threw a scoreless inning while not allowing a baserunner and striking out one Tuesday against the Orioles.

Santana entered the game in the ninth inning with score tied 2-2. He retired the side in order on only 10 pitches, and he has posted a 2.35 ERA and 0.85 WHIP across 15.1 frames since being tagged for five runs by the Rockies on Aug. 1. Santana should continue to serve as Pittsburgh's closer through the end of the campaign.

Ashcraft allowed one earned run on two hits and two walks while striking out four across three innings Wednesday against the Orioles.

Mike Burrows drew the traditional start, but Ashcraft followed him into the game to work in bulk relief. He struggled to consistently hit the zone, with only 36 of his 63 pitches finding the strike zone. While he was inefficient, Ashcraft also racked up seven swinging strikes and recorded all three of his outs in the fifth inning via the strikeout. Ashcraft has a 2.72 ERA and 1.16 WHIP across 36.1 innings since the All-Star break, though most of those appearances have come either in bulk relief or shortened starts.

Agnos (elbow) was scheduled to throw from the slope of a mound Friday, MLB.com reports.

Agnos has been sidelined since the end of July with an elbow injury and is hoping to ramp up in time to return this season. It's unclear whether that will happen, but Agnos appears to be recovering well from the injury.

Halvorsen (elbow) has resumed throwing from 60 feet and is hoping to return from the injured list prior to the end of the season, MLB.com reports.

This marks Halvorsen's first notable progress since he was sidelined in early August with an elbow injury. He hopes to pitch in a game before the season is over, but Halvorsen is expected to be at full strength shortly after the campaign ends if he cannot return.

Walker allowed a hit and a walk in a scoreless inning to earn the save in Tuesday's 5-3 win over the Diamondbacks.

Walker imploded versus the Cardinals on Saturday, and while he wasn't that sharp Tuesday, he was able to get the job done. He's converted five of six save chances over his last seven appearances, and he's been scored on in just two of 14 outings since the start of August. For the season, Walker has a 3.86 ERA, 1.18 WHIP and 55:15 K:BB through 56 innings, and he's converted 15 of 20 save opportunities.
