The Orioles activated Selby (hamstring) from the 15-day injured list Tuesday, Jake Rill of MLB.com reports.

Selby strained his left hamstring July 28 but is healthy after completing a rehab assignment. The 27-year-old right-hander has recorded a 4.09 ERA, 1.55 WHIP and 12:2 K:BB across 11 innings this season for the Orioles.

The Pirates optioned Sisk to Triple-A Indianapolis on Tuesday.

He's being replaced on the roster by Hunter Barco. Sisk has made 19 relief appearances in the majors this season between the Royals and Pirates, posting a 3.57 ERA and 25:10 K:BB over 17.2 frames.

Atlanta optioned Wiles to Triple-A Gwinnett on Tuesday.

He's clearing out to make room on the roster for waiver claim Joel Payamps, who officially reported to the team Tuesday. Wiles' stint in the majors lasted one week and he did not make an appearance.

Zimmermann will start Tuesday's game against the Padres, Adam McCalvy of MLB.com reports.

Zimmermann was promoted to the major leagues Saturday with the expectation that it would be a brief stint, but he'll remain with the Brewers a bit longer after Brandon Woodruff (lat) ended up on the 15-day injured list. Zimmermann has fared well in the minors over his last four outings, cruising to a 1.17 ERA and 0.87 WHIP with 22 strikeouts over 23.0 innings, but he'll face a tough San Diego lineup in his first big-league action of 2025.

Suarez picked up the save Monday against Washington. He allowed five hits and no walks while striking out two over three scoreless innings.

Suarez came in to handle the final three innings Monday, locking down his first save of the year. The southpaw hasn't logged a ton of big-league action, but he's been effective when used, working to a 1.96 ERA and 1.25 WHIP over 18.1 innings across six appearances (one start).

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.
