The Athletics designated Bielak for assignment Saturday.

The move comes with the Athletics recalling right-hander Tyler Ferguson from Triple-A Las Vegas. Oakland acquired Bielak from the Houston on May 16 after the Astros DFA'd the 28-year-old right-hander May 11. Bielak appeared in three games for the Athletics, and he did not give up a run over his last two outings. He's out of minor-league options, but Bielak should still draw interest from teams that are in need of right-handed depth in the bullpen.

Hernandez pitched a perfect inning in Friday's 8-1 win over the Rays.

Hernandez got three straight flyouts from Jonathan Aranda, Randy Arozarena and Jose Caballero to finish off the lopsided game. Hernandez missed nearly two months to begin 2024 as well as all of spring training due to a pinched nerve in his right shoulder. He pitched to an 8.22 ERA, 1.94 WHIP and 12:6 K:BB over 7.2 innings during his rehab assignment with Triple-A Omaha, though he kept runs off the board in five of his last six outings before he was activated. The Royals' bullpen has been OK this year, with James McArthur and John Schreiber leading the way for high-leverage opportunities, so Hernandez is likely to be eased in for his first few appearances.

The Rays reinstated Devenski (knee) from the 15-day injured list Saturday.

Devenski landed on the IL on April 29 due to right knee tendinitis. He made three rehab appearances with Triple-A Durham, and in his last outing he gave up one run on two hits while striking out three over three innings. Devenski will be available for the Rays' weekend series against the Royals, and the 33-year-old right-hander is expected to be used as a long reliever upon his return.

Tarnok (hip) has allowed multiple earned runs in two of his four rehab appearances for Triple-A Las Vegas, pitching to a 10.38 ERA and 1.62 WHIP with a 4:1 K:BB across 4.1 innings.

Tarnok's first and most recent rehab appearances went well, with the right-hander blanking Round Rock over one frame in his minor-league debut May 8 and then bouncing back last Sunday with a pair of perfect innings against El Paso after consecutive rough outings. Tarnok has yet to pitch at the major-league level this season as he completes his recovery from August 2023 hip surgery. He may end up needing his full rehab window with the Aviators, but there could be room for him in the rotation upon activation, considering there are three Athletics starters on the injured list and veteran right-hander Ross Stripling is now sitting on a 1-9 record and a 5.82 ERA across his first 11 starts.

Stewart (shoulder) has been making plyo ball throws as he builds up for a rehab assignment, the St. Paul Pioneer Press reports.

Stewart was placed on the IL on May 3 with right shoulder tendinitis and then had a platelet-rich plasma injection. It sounds like he's making progress but he's still a ways away from a rehab assignment as he likely needs to throw off a mound first.

Urena was removed from his start in Friday's loss to the Twins due to swelling in his left lower leg, MLB.com reports.

Urena was hit by a comebacker in the ankle area of his left leg during the third inning but remained in the game. He made it through another two innings and attempted to warm up for the sixth when the discomfort became too much. Texas manager Bruce Bochy said the team wasn't too concerned about the injury, adding that Urena will be checked out again Saturday.

Foley set down the lone batter he faced to pick up the save in Friday's 6-2 win over Toronto.

Andrew Chafin recorded the first two outs in the ninth inning before allowing four consecutive base hits, allowing the Blue Jays to get the tying run to the plate. However, Foley would come on in relief to set down Danny Jansen for the final out, earning his 11th save this season. Foley's ERA is down to 2.41 on the year with a 1.34 WHIP and 16:7 K:BB across 18.2 innings.

Cano (3-2) allowed a run on one hit and struck out two over one inning Friday, blowing a save but earning the win over the White Sox.

Cano gave up a game-tying solo home run to Andrew Vaughn in the seventh inning, but the Orioles retook the lead in the eighth. Cano's allowed four runs over 3.2 innings across his last six appearances, adding two blown saves and two holds in that span. He has a 3.18 ERA, 1.37 WHIP and 21:9 K:BB over 22.2 innings while picking up two saves, 11 holds and three blown saves. He's still part of the high-leverage mix, but his recent inconsistency may force manager Brandon Hyde to turn to another reliever for save chances if Craig Kimbrel is unavailable at any point.

Hader struck out two in a perfect inning to earn the save in Friday's 6-3 win over the Athletics.

Hader has not allowed a hit over his last five appearances spanning seven innings, and he has a 12:2 K:BB with three saves and two wins in that span. The Astros are trending upward as well, which has given Hader more consistent work. The southpaw is at a 3.91 ERA, 1.04 WHIP and 37:9 K:BB over 23 innings while converting seven of eight save chances this season.

Duran allowed a walk and struck out one batter in a scoreless inning to earn a save over the Rangers on Friday.

Duran worked around a two-out walk to finish off a 3-2 win. He'd been tagged with five runs in 2.2 innings over his previous three outings after beginning the year with a seven-inning scoreless streak. Friday's outing was his first scoreless appearance since May 12 and lowered his ERA to 4.22 alongside an 11:4 K:BB.
