The Pirates optioned Stratton to Triple-A Indianapolis on Friday, Alex Stumpf of MLB.com reports.

Stratton will end up as the Pirates' roster casualty as Domingo German comes up from Triple-A to give Pittsburgh another long relief option. The 27-year-old Stratton got off to a rough start in the majors this season, though he went unscored upon in five innings during his latest stint with the Pirates.

Bukauskas (triceps) was removed from his rehab appearance at Triple-A Nashville on Friday after getting hit by a comebacker, Curt Hogg of the Milwaukee Journal Sentinel reports.

Bukauskas took a 98 mph line drive off his arm and had to leave the game after facing just one batter. The 27-year-old righty was making his fourth appearance at Triple-A since resuming his rehab assignment in late July, but his time in the minors figured to be extended as a result of his latest injury.

The Giants optioned Doval to Triple-A Sacramento on Friday, Maria I. Guardado of MLB.com reports.

The decision to send Doval to the minors comes after he gave up three earned runs in one inning and was charged with his fifth blown save Thursday. The 27-year-old righty will attempt to get back on track with Sacramento after recording a 6.75 ERA and 1.83 WHIP through 21.1 innings since June 2. Ryan Walker and Tyler Rogers are likely the favorites to pitch in save situations for the Giants, and Landen Roupp will come up from Triple-A to replenish San Francisco's bullpen depth.

The Giants recalled Roupp from Triple-A Sacramento on Friday, Maria I. Guardado of MLB.com reports.

Roupp will take Camilo Doval's spot on the active roster, marking Roupp's first MLB action since June 30. In 16.1 big-league innings, Roupp has logged a 6.06 ERA and a 1.65 WHIP with a 15:10 K:BB.

Megill (back) will throw a bullpen session Saturday, Curt Hogg of the Milwaukee Journal Sentinel reports.

Saturday will mark Megill's first time throwing off a mound since a lower-back injury forced him onto the injured list near the end of July. It remains unclear how far away he is from rejoining Milwaukee's bullpen, but the return of Devin Williams means that Megill will almost certainly be moved into a setup role once he's activated.

Pagan (lat) is with the Reds for their weekend series against the Brewers, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Pagan began his rehab assignment Aug. 2, and after throwing two scoreless frames over his first two outings, he gave up two runs on two hits in one inning in his last appearance with Triple-A Louisville on Thursday. The 33-year-old reliever travelled with the team to Milwaukee and could be activated during the weekend series. Pagan has recorded three holds across 22 major-league appearances this season with a 4.43 ERA and 1.38 WHIP over 20.1 innings.

The Diamondbacks recalled McGough from Triple-A Reno on Friday.

McGough owns a 7.33 ERA and 1.70 WHIP through 27 innings in the majors this season, though he's put up a 3.09 ERA across 11.2 frames since being optioned to Triple-A in late June. He'll now return to the big leagues to give the Diamondbacks a fresh bullpen arm, replacing Slade Cecconi.

The Phillies designated Castillo for assignment Friday.

The 25-year-old was sent to Triple-A Lehigh Valley late in spring training after being claimed off waivers from the Red Sox, but he's now been jettisoned from the Phillies' 40-man roster. Castillo struggled to an 8.37 ERA, 1.93 WHIP and 37:24 K:BB over 42 innings (10 starts) at Triple-A.

Atlanta recalled Logue from Triple-A Gwinnett on Friday.

While it'll be Logue's second MLB stint of 2024, he's yet to appear in a game for Atlanta this season. In 20 appearances (12 starts) at Triple-A, the left-hander has logged a 2.93 ERA and a 1.06 WHIP across 83.0 innings. Parker Dunshee was optioned to Gwinnett in a corresponding move.

Atlanta optioned Dunshee to Triple-A Gwinnett on Friday.

Dunshee's contract was selected Thursday, and he threw 2.1 innings in Thursday's 16-7 loss to Milwaukee, allowing five runs on four hits and two walks. The outing marked the 29-year-old's MLB debut. Zach Logue was recalled from Gwinnett in a corresponding move.
