Orioles interim manager Tony Mansolino said Monday that Bautista is going to be "out a while" after an MRI showed significant swelling in the pitcher's right shoulder, Jake Rill of MLB.com reports.

The silver lining is that Bautista does not have any structural damage. However, with the amount of inflammation in his shoulder, he's looking at an absence that will last weeks, not days. With the Orioles not in playoff contention, it's fair to wonder how much of a contribution, if any, he will make the rest of this season. Seranthony Dominguez is the current favorite to see the bulk of the save chances for Baltimore down the stretch, though he is a possibility to be traded.

The Tigers acquired Dobnak and right-hander Chris Paddack from the Twins on Monday in exchange for catcher Enrique Jimenez, Ken Rosenthal of The Athletic reports.

Dobnak made one extended relief appearance for the Twins earlier this season but has spent nearly all of 2025 at Triple-A St. Paul, where he's posted a 7.12 ERA and 42:35 K:BB over 60.2 frames. He's making $3 million this season, so his inclusion in the deal is likely just a means for the Twins to unload a little more salary.

The Guardians recalled Herrin from Triple-A Columbus on Monday.

Herrin will join the Cleveland bullpen in place of Emmanuel Clase (personal), who was placed on administrative leave through Aug. 31 due to his involvement in MLB's gambling investigation. Though the absence of Clase creates a void in the ninth inning, Herrin is likely to be used in middle relief initially rather than factoring into the mix for saves. The 28-year-old lefty has posted a 3.99 ERA, 1.50 WHIP and 28:22 K:BB in 29.1 innings with the big club this season.

The Orioles optioned Hiraldo to Triple-A Norfolk on Monday.

Hiraldo has made two scoreless relief appearances during his brief time in the majors this season. He's clearing out to make space on the active roster for Keegan Akin's (shoulder) return from the 15-day injured list.

The Orioles activated Akin (shoulder) from the 15-day injured list Monday.

Akin missed a month of action with left shoulder inflammation but has been cleared to return after making three rehab appearances. The southpaw should see some high-leverage appearances in the Orioles bullpen, but he could be a candidate to get moved elsewhere ahead of Thursday's trade deadline.

Stephan (elbow) resumed his rehab assignment at Triple-A Columbus over the weekend, issuing one walk in a scoreless inning Friday.

Stephan is in the midst of his second rehab assignment after the Guardians opted to extend his stay in the minors when his initial 30-day window expired shortly before the All-Star break. During the initial assignment, Stephan made eight appearances across stops with three affiliates and logged a 5.40 ERA and 1.44 WHIP in 8.1 innings. Stephan has made two appearances for Columbus during his second assignment, with Friday's outing marking his first since the All-Star break. The right-hander will likely need to sharpen his command and pitch on consecutive days at Triple-A before the Guardians bring him back from the 60-day injured list.

Sewald (shoulder) was diagnosed with a moderate teres major strain after undergoing an MRI over the All-Star break, MLB.com reports.

Sewald was initially placed on the injured list July 15 due to a right shoulder strain, but the Guardians didn't offer up a timeline for his return. The fact that Sewald has been diagnosed with a moderate strain rather than a mild one suggests that he likely won't be in line for a brief stint on the shelf, and his absence could end up stretching into September. Prior to landing on the shelf, Sewald made 18 appearances out of the Cleveland bullpen and logged a 4.70 ERA, 1.17 WHIP and 18:4 K:BB in 15.1 innings.

The Guardians announced Monday that Clase has been placed on non-disciplinary paid leave through Aug. 31 as part of MLB's sports-betting investigation, Zack Meisel of The Athletic reports.

Clase becomes the second Guardians pitcher to be placed on the restricted list in connection with the investigation, as right-hander Luis L. Ortiz previously went on leave earlier in this month. The 27-year-old righty has taken a step back statistically this season but has still performed as one of baseball's top closers, notching saves in 24 of 29 chances while logging a 3.23 ERA and 1.23 WHIP in 47.1 innings. The 52-53 Guardians are 3.5 games behind for the final wild-card spot in the American League and may have considered moving Clase ahead of Thursday's trade deadline, but his placement on non-disciplinary leave likely takes any potential deal off the table. While Clase is out for at least the next month, right-hander Cade Smith (3.02 ERA, 1.19 WHIP and 65:17 K:BB in 44.2 innings) looks like the next man up for save chances in the Cleveland bullpen, though manager Stephen Vogt could opt for a committee approach at closer.

The Twins selected Tonkin's contract from Triple-A St. Paul on Monday.

Tonkin has spent all of this season in the minors, posting a 4.82 ERA but a much more promising 34:7 K:BB over 28 innings with St. Paul. He will give manager Rocco Baldelli a fresh bullpen arm.

Marsh received an injection for his sore right shoulder last week, MLB.com reports.

Marsh has yet to pitch at any level this season after he first experienced shoulder tightness early on during spring training before suffering multiple setbacks in the subsequent months. He's in the midst of a rest period while he waits for the injection to alleviate the discomfort in his shoulder, but if the shot provides the desired effect, he could soon restart a throwing program. Even if he's able to steer clear of any further setbacks, Marsh will likely require an extended ramp-up program and probably won't be a realistic candidate to return from the 60-day injured list until late August at the soonest.
