The bullpen is about to undergo another change.

This one comes from outside the organization.

The Orioles traded Triple-A Norfolk pitcher Garrett Stallings to the Brewers this afternoon for right-handers Thyago Vieira and Aneuris Rodriguez. Vieria hasn’t reported, and the 40-man roster will be full upon his arrival. Rodriguez will head down to the Florida Complex League.

Vieira, 31, had a 5.64 ERA, 1.701 WHIP and one save in 16 appearances with the Brewers. He owns a career 6.18 ERA and 1.667 WHIP in 41 games with the Mariners, White Sox and Brewers, making his major league debut in 2017. He pitched in Japan from 2020-22.

The fastball averaged 98 mph this season and his sinker has plus velocity at 96.9, but he’s averaging 4.9 walks per nine innings in the majors to go with nine strikeouts. He’s averaged 4.5 walks in 10 minor league seasons.

CHICAGO – Kyle Stowers is in left field today and Ramón Urías is the third baseman, as the Orioles try to win a third consecutive game after being swept in St. Louis.

Ryan O’Hearn is in right field. Colton Cowser returns to center field after last night’s leaping catch at the fence to rob Tommy Pham of a home run and end the game.

Jordan Westburg’s RBI double last night snapped an 0-for-13 streak. He’s the second baseman today.

Gunnar Henderson and Houston’s Kyle Tucker are tied for the major league home run lead with 17. Henderson is swinging 56.1 percent of the time with two strikes, with eight of his home runs coming in those counts, per STATS.

Albert Suárez is making the start after the Orioles put Dean Kremer on the 15-day injured list with a strained right triceps. He’s made 10 appearances, the last seven in relief, and registered a posted a 1.78 ERA and 0.947 WHIP in 25 1/3 innings.

CHICAGO – The Orioles won’t completely empty their injured list this season because closer Félix Bautista is on the 60-day and unavailable until 2025. He’s playing catch and posting videos of his workouts in Sarasota.

They got it down to two names, including Tyler Wells, before John Means and Dean Kremer hopped on this week on back-to-back days. Health progress is made and then erased.

To borrow a Bruce Springsteen lyric, one step up and two steps back.

Five starters have gone on the injured list. Ace Corbin Burnes and left-hander Cole Irvin, temporarily moved to the bullpen, have managed to avoid it.

Knuckles rap on wood at the mere mention of it.

CHICAGO – Orioles manager Brandon Hyde explained earlier in the day why Adley Rutschman wasn’t in the lineup. Had nothing to do with an injury. That’s reserved for the rotation.

Three consecutive day games were on the docket. This was a way to give the catcher a little break before the grind.

Hyde smiled as he sat in the visiting dugout and conceded that Rutschman probably would get in there anyway. That’s usually how it works.

Rutschman came off the bench in the eighth inning and singled with two outs to score two runs, breaking a tie and giving the Orioles a 6-4 victory over the White Sox before an announced crowd of 18,831 at Guaranteed Rate Field that ensures nothing less than a split of the four-game series.

The Orioles are 31-18 and starting Albert Suárez on Saturday afternoon after placing Dean Kremer on the 15-day injured list with a strained right triceps.

CHICAGO - The Orioles aren’t listing a starter for Saturday afternoon’s game against the White Sox. They can go in a few directions. Calling upon Dean Kremer isn't among them.

Kremer was supposed to get the ball on his normal turn, but he’s on the 15-day injured list with a strained right triceps. Manager Brandon Hyde said he could make the announcement after tonight’s game.

“This is still pretty fresh so we’re still talking about it,” Hyde said.

Albert Suárez is the in-house candidate. He can provide some length.

Meanwhile, left-hander Cade Povich is scheduled to start Saturday for Triple-A Norfolk in Worcester. The No. 9 prospect in the system per MLB Pipeline is 5-1 with a 2.08 ERA and 1.049 WHIP in nine games and is averaging 12.3 strikeouts per nine innings. His walk rate is down to 3.2, compared to 5.8 last year in 10 starts with the Tides.

CHICAGO - The Orioles are running out of starters.

The team announced today that it placed Dean Kremer on the 15-day injured list with a right triceps strain, retroactive to Tuesday. They also optioned Jonathan Heasley to Triple-A Norfolk.

On the other side of the transaction, the Orioles recalled relievers Dillon Tate and Nick Vespi from Norfolk.

Kremer was supposed to start Saturday afternoon against the White Sox. He’s joining John Means on the IL.

Kremer is 3-4 with a 4.32 ERA and 1.120 WHIP in nine starts. He’s allowed eight earned runs and 11 total in his last two games covering 9 2/3 innings.

Teammates felt sharp pangs of sympathy for Orioles pitcher John Means, experiencing their own discomfort after he packed up his belongings Wednesday and flew back to Baltimore.

They don’t know when they’ll see him again, though early next week at Camden Yards is most likely. They don’t know how long he’ll be on the injured list or when he’ll start again. No one had answers yesterday.

None of it seemed fair.

Means returns from ligament-reconstructive surgery in his elbow and a strained muscle in his upper back, only to be shelved by a strained left forearm that keeps him off the Division Series roster. He accepts that he’ll begin the 2024 season on the injured list, is reinstated, and returns to it after only four starts and with his ERA at 2.61 and WHIP at 0.871.

“It’s so hard to hear,” said reliever Danny Coulombe. “John just worked his tail off to get back. Nobody can ever question his work ethic. But his body didn’t cooperate and we’re just hoping and praying for the best.

CHICAGO – One of the starting pitchers was back in Baltimore having his left elbow examined. Multiple relievers were unavailable following a couple of rain delays and a suspended game in St. Louis, which necessitated the arrival of Jonathan Heasley in a potential bulk role.

The Orioles had lost three in a row and seen much better days when they arrived in Chicago to begin their series against the White Sox, and that was before Grayson Rodriguez threw 30 pitches in the first inning.

They fell behind twice tonight to the team with the worst record in baseball. The team that’s scored the fewest runs. But they snapped out of their funk in the fourth inning.

Finally, they could feel good again. They were due for it.

They just had to sweat a little in the ninth.

CHICAGO – John Means has returned to Baltimore and is undergoing further examinations and testing on his sore left elbow.

Means went on the 15-day injured list today with a left forearm strain after tossing three scoreless innings yesterday in St. Louis but experiencing discomfort that caused him to occasionally flex his arm. He obviously was uncomfortable on the mound.

“He’s meeting with the doctors in Baltimore and just haven’t gotten the results back yet,” manager Brandon Hyde said. “He’s meeting with them this afternoon and we’re hoping for the best.

“It was disappointing because he’s worked so hard to get back and was a huge boost for us in September last year after the long road back. Was throwing the ball well. You could tell something was a little bit off yesterday, but hopefully we get good news today.”

Means couldn’t pitch in the 2023 Division Series due to a forearm strain, and he went on the injured list Opening Day to get built up after a late start to his winter throwing program.

CHICAGO – Jordan Westburg is batting fifth tonight and playing third base in the series opener in Chicago.

Colton Cowser is in left field, Cedric Mullins is in center and Anthony Santander is in right.

Ryan Mountcastle is the first baseman, with Ryan O’Hearn serving as designated hitter.

Adley Rutschman leads the Orioles with 56 hits. He joins Milwaukee’s William Contreras (65) as the only catchers ranking first on their teams.

Grayson Rodriguez has a streak of 12 straight scoreless innings, third-longest by an Orioles starter behind Cole Irvin’s 22 2/3 and Albert Suárez’s 12 1/3.

CHICAGO – John Means is returning to the 15-day injured list.

The Orioles announced today that Means has been diagnosed with a left forearm strain, the same ailment that delayed his 2024 debut.

Reliever Jonathan Heasley was recalled from Triple-A Norfolk to replace Means on the roster.

Means tossed three scoreless innings yesterday in St. Louis but was flexing his arm and experiencing a noticeable decline in velocity across the board. The game was interrupted by rain but Means wasn’t returning for the fourth.

This is the latest setback for Means, who returned from Tommy John surgery last September, made four starts and missed the Division Series due to the forearm strain.

The Orioles have talked about going to a six-man rotation, certainly by the brutal stretch in June with only one day off. In the meantime, Cole Irvin pitches out of the bullpen and waits to find out if he’s bouncing between roles again.

Too many starters? We heard it before Kyle Bradish and John Means were reinstated from the injured list. Tyler Wells and Grayson Rodriguez were sidelined by inflammation in the elbow and shoulder, respectively. These things, yes, have a way of working themselves out.

Means made his fourth start yesterday and tossed three scoreless innings against the Cardinals with only one hit allowed. He threw 51 pitches and Irvin replaced him after inclement weather forced another interruption.

Toasted ravioli and rain delays. It’s what St. Louis does.

Was a storm the only reason Means came out of the game? Unfortunately, no.

Teammates knew that reliever Mike Baumann wouldn’t clear waivers after the Orioles designated him for assignment. He’d most likely be traded rather than relinquished for no return.

They were right.

The Orioles announced late tonight that they’ve traded Baumann and Triple-A Norfolk catcher Michael Pérez to the Mariners for catcher Blake Hunt. Hunt was optioned to Norfolk.

Hunt, 25, is batting .293/.372/.533 with four doubles, a triple, four home runs, 20 RBIs, six walks and 15 runs scored in 23 games with Triple-A Tacoma. He’s also been hit by four pitches.

He knows how to get on base.

The Orioles completed their suspended game today with a 3-1 loss to the Cardinals, setting up this afternoon’s series finale before the charter flight to Chicago.

A win is needed to prevent the sweepless streak in the regular season from ending at 106 series.

Nolan Gorman hit a two-run homer off Keegan Akin in the sixth inning to break a 1-1 tie. Akin inherited a runner from Jacob Webb.

Ryan Mountcastle singled today to interrupt a 1-for-26 slump. He’s on the bench for the second game.

Left-hander Nick Vespi was added as the 27^th man. The Cardinals added right-hander Chris Roycroft.

Most of Trey Mancini’s swings are now done with a tennis racket. He’s living in Miami with wife Sara Perlman, his last baseball game played in spring training with the Marlins before they granted his release on March 23. Interest from other teams hasn’t really percolated and he’s fine with any outcome.

The Cubs are paying Mancini through the rest of the season after signing him to a two-year, $14 million deal in January 2023. They released him seven months later after he batted .234/.299/.336 with 12 doubles and four home runs in 79 games, and he spent a week in the Reds organization, appearing in five games with Triple-A Louisville and going 6-for-19 with two doubles and two home runs.

That release was followed by a minor league deal with the Marlins in January, a 9-for-35 spring with a double and home run, and the opt-out after being told that he wouldn’t make the club.

Mancini, 32, has a World Series ring with the Astros but his finest seasons and fondest memories are with the Orioles, who drafted him in 2013 and brought him to the majors three years later. They traded him at the 2022 deadline while in contention, an unpopular move with fans but not unexpected with free agency pending.

Nothing is more important than what follows here: Trey Mancini has been cancer-free for four years.

Ryan Mountcastle is in tonight’s lineup at first base, as the Orioles try to even their series in St. Louis.

Mountcastle came off the bench last night. He hadn’t been in the lineup for two of the last three games.

Kyle Stowers is in right field. Ryan O’Hearn is the designated hitter.

Anthony Santander, playing with a bruised left knee, is on the bench.

Jordan Westburg is batting cleanup again.

Constant fluctuations in run production are expected over the course of a 162-game regular season. The dam bursts and is rebuilt.

The Orioles were shut out against the Yankees on May 1 and scored seven runs the following day. They beat the Reds 2-1 in Cincinnati, erupted for 11 runs in the next game and lost 3-0 in D.C. They totaled seven runs in a three-game stretch, opened the weekend Mariners series with a 9-2 win and were no-hit last night through five innings before Gunnar Henderson's three-run homer off Sonny Gray.

The club ranked 21^st in the majors in runs scored this month with 64 heading into last night’s game in St. Louis after ranking fourth in the majors and first in the American League with 132 in April.

“We’re just continuing to work through it,” said co-hitting coach Matt Borgschulte. “We just want to continue to take good at-bats and put pressure on the pitcher and hopefully continue to grind out some more good at-bats like we did (Saturday) night and first game of the series.”

Austin Hays was putting together better at-bats right before his left calf strain in Kansas City. He had hits in five of six games heading into last night.

Ryan Mountcastle is out of the Orioles lineup again tonight to begin a three-game series in St. Louis.

Mountcastle sat out Saturday's game and played first base yesterday. He had two doubles and a triple on May 11 but has one hit in his last 20 at-bats. He hasn’t drawn a walk since April 24.

Anthony Santander, who’s receiving treatment on a bruised and swollen left knee, is the designated hitter.

Jordan Westburg is batting cleanup for the second time in his career.

Cedric Mullins is in center field. Mullins stole his 100^th career base yesterday and needs three more to tie Corey Patterson for eighth in club history.

Cole Irvin understands the situation. The sub-3.00 ERA and the scoreless streak that reached 22 2/3 innings don’t make him immune to a sudden switch in roles.

Irvin would have started Wednesday afternoon against the Blue Jays if inclement weather hadn’t forced a postponement the previous night. He’s skipped in the rotation and sitting with the relievers.

The Orioles are listing Dean Kremer, Kyle Bradish and John Means for the series in St. Louis. Grayson Rodriguez and Corbin Burnes would work on normal rest if they start the first two games in Chicago.

Irvin could hop back into the rotation, which is going to expand to six starters with one off-day in June. In the meantime, he’s finding ways to prevent any rust from accumulating, getting in his throwing without letting it impact his availability.

“We need another bullpen guy,” he said yesterday morning. “Unfortunately, we lost Big Mike (Baumann) and we need Grayson back and he’s healthy. Just a numbers thing, you know? I’m going to do my job the way I was doing it at the beginning of the year, the way I did it last year. Like, whatever the team needs of me I’m going to do. So, just keeping it simple, don’t think about it too much other than I have a job to do now out in the bullpen.”

Gunnar Henderson has got the routine down to where he could perform it in his sleep. But it makes more sense at the ballpark.

The loud contact leading off the first inning. Touching the bill of his helmet as he approaches second base and looks at the bullpen. The hop after stepping on home plate and slapping of hands above his head. The crouching low-five to the No. 2 hitter. The upright and aggressive double-smack with the next batter in front of the dugout.

Jordan Westburg greeted Henderson first today and Ryan O’Hearn was next in line. The major league co-leader in home runs got his 15^th today and fifth to start off the first inning. It doesn’t matter who’s on the mound. Henderson is in attack mode and flashing power that’s Derby worthy.

Henderson’s third homer in three days pointed the Orioles toward a 6-3 victory over the Mariners before an announced crowd of 30,494 at Camden Yards. They went 5-3 on the homestand, with a game rained out, and are 29-15 as they board a flight to St. Louis.

Corbin Burnes held Seattle to one run over six innings, scattering seven hits and tying his season high of 11 strikeouts from Opening Day. He struck out two in his last outing, a career low as a starter.
