Rios (undisclosed) was activated from the 60-day injured list Thursday.

Rios missed the majority of the 2025 campaign due to an unspecified injury but has since returned to Triple-A Syracuse. He had a rough outing Sept. 18 against Lehigh Valley, getting knocked around for four runs on three hits and one walk while striking out one, but he responded nicely with a scoreless inning Sunday.

The Angels optioned Peralta to Triple-A Salt Lake on Monday.

The move corresponds with the Angels reinstating Ryan Zeferjahn (knee) from the 15-day injured list. Peralta joined the big club Sept. 7 after spending most of the season in Triple-A, but in just four major-league appearances he allowed 12 runs (nine earned) on 14 hits and six walks while striking out seven across 9.2 innings.

The Angels reinstated Zeferjahn (knee) from the 15-day injured list Monday.

Zeferjahn landed on the 15-day IL in early September due to right knee tendinitis, but he has been cleared to return to the majors despite not going on a rehab assignment. The 27-year-old right-hander posted a 3.20 ERA, 1.17 WHIP and 31:11 K:BB across 19.2 innings in 19 games since the All-Star break.

Atlanta designated Ragsdale for assignment Monday.

The transaction frees up a spot on the 40-man roster for the addition of Charlie Morton, who was signed Monday. Ragsdale was just claimed off waivers by Atlanta last week and will now go through the waivers process again.

Atlanta designated Seabold for assignment Monday.

The transaction frees up a spot on the 40-man roster for the addition of waiver claim Joel Payamps. Seabold has yielded five runs with a 10:6 K:BB over 10.1 frames at the big-league level in 2025 and is a good bet to clear waivers.

Atlanta claimed Payamps off waivers from the Brewers on Monday.

Payamps was a staple in the Milwaukee bullpen from 2023 to 2024, holding a 2.78 ERA and 136:35 K:BB over 129.2 innings. However, he's experienced sharp regression in 2025, posting a 7.23 ERA with the Brewers and spending much of the campaign in the minors. Atlanta will give him a look in the final week of the season and could keep him for 2026, as well, if it wants to tender the reliever a contract in his final year of arbitration eligibility.

Vargas allowed one run on one hit in 1.2 innings Sunday against the Astros. He struck out one.

Vargas has been a liability out of the Seattle bullpen of late, giving up at least one run in three of his last four outings. The right-hander has mostly worked as a middle reliever and in low-leverage situations in 2025, and that's unlikely to change at this stage of the season while the Mariners try to clinch a playoff berth. Through 74 frames, Vargas has a 4.01 ERA, 1.35 WHIP and 51:23 K:BB with 14 holds while converting just one of his eight save opportunities.

Ferguson allowed one run on three hits in one-third of an inning Sunday against the Astros.

The Mariners acquired Ferguson from the Pirates ahead of the trade deadline to bolster their bullpen, but he hasn't been particularly reliable for his new team. Through 18.1 innings for Seattle, the southpaw has a 3.93 ERA, 1.53 WHIP and 14:7 K:BB. Given Ferguson's shakiness, Gabe Speier will likely remain the preferred left-handed high-leverage arm for the M's in the future.

Treinen (1-7) was charged with a loss and a blown save against San Francisco on Sunday, allowing three runs on three hits and two walks with no strikeouts over two-thirds of an inning.

After Emmet Sheehan gave the Dodgers seven scoreless, one-hit innings, Treinen entered in the eighth to try to preserve a 1-0 lead. The veteran reliever got into trouble immediately, allowing a pair of singles and then a ground-rule, run-scoring double as San Francisco tied the score. Treinen next retired his first batter, but he followed an intentional walk with a non-intentional one to force in another run, then allowed an RBI groundout for the final tally on his line. It's been a very rough September for the right-hander, who has posted an uncharacteristic 11.57 ERA, 2.43 WHIP and 6:9 K:BB while taking five losses over nine appearances spanning seven innings this month. Treinen was a big part of Los Angeles' run to the championship last year, but it's fair to wonder if manager Dave Roberts will feel comfortable going to him in high-leverage situations at the start of the postseason given Treinen's recent struggles.

Miller earned a hold against the White Sox on Sunday, walking two batters and striking out one over a hitless and scoreless two-thirds of an inning.

Miller wasn't at his best in the outing, throwing just eight of 19 pitches for strikes. He entered with the bases loaded and one out in the seventh frame, so each of his two walks forced in a run, but he was able to escape the inning with the Padres still in the lead. Though this was far from his best performance, Miller extended to 18 his streak of scoreless appearances. The talented reliever has tossed 19 innings during that span, giving up just four hits while posting a sizzling 36:8 K:BB and recording nine holds with one save.
