Santillan (back) was pulled off his rehab assignment Friday due to right knee discomfort.

Santillan had been pushing toward his season debut after battling a back injury last year and again this spring, but that plan will be put on hold due to this knee issue he picked up at Triple-A Louisville. The severity of the setback is not yet clear.

Stephenson (elbow) was activated Friday from the 15-day injured list.

Stephenson will join the Pirates' bullpen Friday night in St. Louis after missing the first three weeks of the 2023 regular season due to right elbow soreness. He could eventually work his way into a prominent setup role, though Pittsburgh's relief corps has been impressive all around in the early going.

Oller was optioned to Triple-A Las Vegas on Friday.

After surrendering seven runs over 2.1 innings Thursday against Baltimore, Oller earned himself a trip back to the minors. The 28-year-old righty posted a 3.69 ERA and 1.47 WHIP over 31.2 innings across seven Triple-A starts last season, and he could find himself bouncing frequently between the minors and the majors in 2023 as the Oakland bullpen needs fresh arms.

Harris was recalled by the Athletics on Friday.

The 26-year-old lefty has yet to appear in a big-league game. Harris has made 10 starts in Triple-A since 2022 and holds a 6.34 ERA and 1.84 WHIP across 32.2 innings in that time. Adam Oller was optioned to Triple-A Las Vegas in a corresponding move, so Harris will most likely take Oller's spot in the bullpen as a multi-inning reliever.

Hjelle was recalled Friday from Triple-A Sacramento, Alex Pavlovic of NBC Sports Bay Area reports.

Hjelle was just sent down Wednesday, but the Giants had an opening on their 26-man roster after having to place outfielder Bryce Johnson on the 7-day concussion IL. Hjelle will get another look out of the bullpen.

Sborz was activated from the 15-day injured list by the Rangers on Friday.

Sborz got a late start to the season due to a sprained ankle, but he's ready to go now. The right-hander will fill a middle-relief role with the Rangers.

Brieske (arm) is slated to throw a bullpen session by the middle of next week, Evan Petzold of the Detroit Free Press reports.

Brieske played catch Thursday for the first time since undergoing a hydrodissection procedure to treat a nerve issue in his right arm and will progress to mound work in a few days. There's no timetable yet for his return.

Foster was transferred to the 60-day injured list by the White Sox on Friday with a right flexor strain.

The move frees up a spot on the 40-man roster and ensures that Foster won't make it back until at least late May. It's not clear whether the reliever is in the midst of a throwing program or remains shut down.

Weissert was recalled by the Yankees on Friday.

Weissert appeared in 12 games for the Yankees last season, surrendering seven earned runs across 11.1 innings out of the bullpen. He's gotten off to a much better start this year with Triple-A Scranton/Wilkes-Barre (1.69 ERA, 0.39 WHIP, 5.1 IP) and will look to provide New York's bullpen with some reinforcements. Colten Brewer was designated for assignment in a corresponding move.

Bristo was optioned to Triple-A Durham by the Rays on Friday, Neil Solondz of the Rays Radio Network reports.

Bristo picked up a three-inning save in his major-league debut Thursday versus the Red Sox, not yielding a hit and fanning four along the way. Unfortunately for him, he wasn't going to be available for a few days after throwing 42 pitches, hence the demotion. Bristo put himself in a good spot to earn another look down the line, though.
