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.

ST. LOUIS – The Orioles may be back to having one closer, and it’s once again veteran Craig Kimbrel. He buzzed through the ninth inning Sunday on 14 pitches with two strikeouts, recording the ninth save of his year and the 426th of his career. 

Over his past four games, he has thrown four hitless and scoreless innings, lowering his ERA from 4.73 to 3.63, with no walks and six strikeouts in that span.

So is he the main ninth-inning guy again?

“Well yeah, I think so. Probably,” manager Brandon Hyde said this afternoon at Busch Stadium before the opener of the series and the road trip in St. Louis. “I’m going to see how he feels today. … He looked great yesterday. That was awesome. Really happy. Nice to get him a three-run lead, have a little cushion there. But I thought the stuff was outstanding.”

The Orioles are reunited today with their good friend and 2023 teammate, right-hander Kyle Gibson. He pitched to a 4.73 ERA over 192 innings for the Orioles and is 3-2 with a 4.09 ERA for the Cardinals and will face the O’s Wednesday afternoon.

Vladimir Guerrero Jr. grounded a pitch from Kyle Bradish up the middle Wednesday afternoon with two outs in the third inning, and George Springer surely thought he was going to score from second base. Shortstop Gunnar Henderson couldn’t make a diving stop. He appeared to be the last line of defense.

Jorge Mateo had other ideas, and his ridiculous range.

Mateo darted past the bag and corralled the ball to hold Springer at third base. Unfortunately for the Orioles, Bo Bichette followed with a fly ball to the right field warning track that Anthony Santander couldn’t grab before his knee slammed into the wall, resulting in two runs and a 2-1 lead.

The Fielding Bible Award winner at shortstop in 2022 is excelling at second base this year, to the point where he’s pretty much got regular duty rather than working in a utility role.

The play Wednesday wasn’t the only example of the vast territory he can cover. Remember how he hustled to first base to take the relay throw on a double play? How often does that happen?

Grayson Rodriguez is eligible to return from the injured list on Wednesday and he seems to be trending in the right direction.

Rodriguez said he threw about 30 pitches this morning in his latest bullpen session, about double his amount Wednesday in D.C.

“I felt great,” he said.

Rodriguez said he’ll probably throw another ‘pen in the next few days, and the Orioles can decide whether he should go on a brief rehab assignment.

The right-hander’s preference, of course, is to get back on the active roster.

The late-inning bullpen decisions today by the Orioles were lacking in intrigue and excitement. Nothing about the closer. Nothing about protecting a lead. The top story angle also was being reset.

And then, the threat arrived when Anthony Santander hit a home run with two outs in the eighth inning to tie the game. Perhaps there was hope for hysteria after all.  

The movements and usages of the relievers were back to being Baltimore obsessions, but the Orioles didn’t let the game carry to a save situation. Better to just walk it off and win the series.

The Orioles fell behind in the fifth inning before Santander’s 410-foot shot to center off Diamondbacks reliever Kevin Ginkel, and Jordan Westburg poked a single down the right field line on Bryce Jarvis' first pitch of the 11th to score Colton Cowser in a 5-4 victory before an announced crowd of 27,882 at Camden Yards.

Danny Coulombe retired the three batters he faced without the automatic runner budging from second base, Craig Kimbrel hit Christian Walker but stranded runners on the corners in the 11th with a strikeout and force play, and the Orioles improved to 26-12.

Craig Kimbrel stood up tonight, removed his jacket and began to throw in the Orioles’ bullpen.

It was the bottom of the sixth inning.

Kimbrel said earlier in the day that he expected to get the ball again in a save situation, but he jogged onto the field for the top of the seventh with the Orioles ahead 3-2. The lights flickered as if he were closing. The entrance didn’t change.

Just the timing of it.

Kimbrel retired the Diamondbacks in order on a 101.4 mph line drive to Ryan Mountcastle, a strikeout at 94.4 mph and a fly ball near the warning track in right field. Twelve pitches, eight for strikes, and Kimbrel was done.

Albert Suárez made a run at a rotation spot in spring training, faltered late and was reassigned to minor league camp. He was an unexpected addition to the roster on April 17 after the Orioles placed Tyler Wells on the 15-day injured list with right elbow inflammation. And he keeps finding ways to contribute.

Maybe to complicate, too.

Two starts produced a combined 11 1/3 scoreless innings, because the man is full of surprises. The Orioles ran out of room in the rotation and moved him to the bullpen, where he retired all seven Cincinnati batters he faced Sunday afternoon.

“He made it look pretty easy,” said manager Brandon Hyde.

Nothing was simple about Suárez’s assignment Wednesday night in D.C. The 10^th inning, automatic runner on second base, game on the line. Luis García Jr. didn’t budge because Suárez induced a grounder and fly ball and struck out Joey Meneses on a 96 mph four-seamer to keep the score tied.

WASHINGTON – Kyle Bradish backed up home plate in the second inning and glanced at his glove, as if checking whether a hole had gone undetected.

That isn't where the leak would spring later in the night.

Trey Lipscomb’s one-hopper made it past Bradish, who reached across his body and rested the glove on his right shoulder as the ball bounced into center field for a run-scoring single.

The Orioles were behind again in D.C. Bradish finished the inning at 44 pitches, stranding two runners by fielding Jacob Young’s high chopper and striking out CJ Abrams. But he’d need to become more economical to get deep in his second start since his reinstatement from the injured list, and the Orioles would need a rally to avoid their first series sweep in the regular season since May 2022.

Anthony Santander hit a game-tying home run in the fourth inning and Gunnar Henderson provided a lead leading off the sixth. Bradish struck out nine batters in five frames and became the pitcher of record. It was setting up ideally until closing again became a major issue.

John Means makes his 2024 debut tonight as the Orioles continue their series in Cincinnati following last night’s 3-0 win. And after Cole Irvin ran his scoreless streak to 20 2/3 innings.

Means hasn’t pitched for the Orioles since Sept. 29 against the Red Sox, when he allowed two runs and three hits in 6 1/3 innings. He faced teammates in a simulated game at Camden Yards prior to the Division Series and experienced discomfort in his elbow/forearm area that led to his exclusion from the roster, a delayed off-season throwing program and stint on the injured list.

Tonight marks his latest comeback to the rotation, and he’s with a club that’s 21-11, has won 13 of its last 18 games and is one ahead of the Yankees for first place.

The Reds are a new opponent for Means, who’s posted a career 3.97 ERA in 13 starts against the National League.

Jeimer Candelario is 3-for-8 with a double, triple, RBI and walk against him. Santiago Espinal is 2-for-2 with a double and RBI.

Orioles right-hander Kyle Bradish fired a 96.3 mph two-seam fastball to Yankees leadoff hitter Anthony Volpe for a called strike. And not only was Game 4 of this series underway, but so was Bradish’s first big league outing since last October’s American League Division Series.

He was activated today off the 15-day injured list after dealing with a right UCL sprain that led to him getting a platelet-rich plasma injection in January. After three minor league rehab games, he was back on a big league mound for the first time since he faced the Rangers in Game 1 of the ALDS at Oriole Park on Oct. 7.

Bradish’s return was no doubt a lift today for the Orioles and he gave them a solid outing. They used that, a couple of home runs from unexpected places and Jordan Westburg’s two-run triple to beat the Yankees 7-2 in front of 27,299 sun-splashed fans and take three of four in this series.

The Orioles began this series down a game in the AL East, but they leave it at 20-11 and leading the Yankees (20-13) by a game.

The O’s offense had scored just six runs on 16 hits the first three games of this series, but they broke out today versus Yankees lefty Carlos Rodón, who entered with a 2.48 ERA.

Coming off a series loss to Oakland and preparing to face a Yankees team at Camden Yards that scored 15 runs each the last two days, the Orioles have to quickly move on from their tough weekend with the Athletics.

“Yeah, absolutely,” outfielder Colton Cowser said this afternoon in the Baltimore clubhouse. “You have to have a short memory in this league. Got the Yankees coming to town, so it’s good to have a short memory and get on to the next one.”

Added Ryan Mountcastle: “It’s a new series and new day. We’re excited to get this series going and, hopefully, get some wins.”

It’s a battle for first over the next four days in Baltimore with New York (19-10) on top of the division by one game over the Orioles (17-10).

The Orioles are 3-0 in American League East games with a series sweep at Boston. New York has gone 5-4 in two series versus Toronto and one with Tampa Bay.

Craig Kimbrel attracted two mound visits today from manager Brandon Hyde and head athletic trainer Brian Ebel. The first, after the veteran closer issued a four-pitch walk to the first batter he faced in the top of the ninth inning and fell behind 1-0 to the next. The last, after Oakland's Kyle McCann hit a go-ahead two-run homer and Kimbrel fell behind again 1-0.

A second consecutive blown save from Kimbrel might not be the worst news.

Kimbrel walked off the mound with Ebel while Hyde signaled for Dillon Tate, and the Orioles lost 7-6 before an announced crowd of 40,887 at sun-splashed Camden Yards.

Another attempt failed to record his eighth save this season and the 425^th of his career, which would tie the Red Sox’s Kenley Jansen for fifth place on the all-time list. Kimbrel's fastball was in the mid-90s, but something obviously wasn't right.

Hyde said afterward that Kimbrel had upper-back tightness." Kimbrel was in the trainers' room and unavailable to the media.

The Orioles are close to testing the age-old baseball theory that teams never can have too much pitching.

Cole Irvin must wonder how he plays into the experiment.

Kyle Bradish is leaving his injury rehab assignment and starting for the Orioles next week. John Means makes his final rehab appearance on Sunday, which sets up his return.

The process of elimination could make Irvin vulnerable to a bullpen shift, but the timing would be peculiar given his recent dominance. A whole new meaning to leaving on a high note.

Irvin stated his case again today at high volume to be left alone. After tossing 6 2/3 scoreless innings last weekend in Kansas City, he shut out the Athletics for seven in a 7-0 victory before an announced crowd of 28,364 at chilly and damp Camden Yards.

After letting a one-run lead in the ninth get away in last night’s 3-2 loss in 10 innings to Oakland, the Orioles (16-9) host the Athletics (11-16) today in the second of a three-game series.

Oakland has scored three runs or less in eight straight games, scoring 21 in that span. They have also homered in each of the eight games and this is now the longest such streak in MLB history.

Overall, the A’s have homered in 11 consecutive games (15 home runs total), which is the longest such streak by an A’s team over the last three seasons. The last longer streak was a 13-game streak from Aug. 1-16, 2021.

After Friday’s win, the Athletics are 6-5 in one-run games. The 11 one-run decisions are tied with the Yankees for the most in the majors. However, four of their losses have been by eight or more runs so Oakland has a run differential of -37, which is the fourth lowest in the majors.

Going into Friday’s series opener, the Orioles had scored at least seven runs in four straight games against the A’s. Baltimore has never scored 7+ runs in five consecutive games against Oakland and won’t in this run after being held to two runs Friday. The Orioles are 0-5 when scoring two runs or less.

ANAHEIM, Calif. – Lefty John Means made a fifth rehab appearance on the farm last night, pitching for Triple-A Norfolk. His next turn is likely to come Sunday and it’s possible that could be in Baltimore versus the Athletics.

While Corbin Burnes, Cole Irvin and Albert Suárez have been listed to go Friday through Sunday in that series, that is subject to change pending Means’ status.

“We’re talking about that right now,” manager Brandon Hyde said this afternoon. “He feels really good after that start. He gave up seven singles, they were not very well hit, the stuff is much improved. He’s really encouraged about how he felt during the outing and today.”

Means’ results have not been great in those five games with an ERA of 13.85 in 11 2/3 innings. But it's more about how he is feeling and his pitch quality and pitch count, which reached 79 last night. He could make another rehab start if the Orioles decide he needs that, or they could call him to Baltimore for the next one.

“It’s possibly Sunday, one more with Norfolk or with us. We’re discussing that now,” Hyde said.

With the Angels starting left-hander Tyler Anderson in today’s rubber match in Anaheim, Orioles manager Brandon Hyde posted a lineup that doesn’t included Heston Kjerstad or Jackson Holliday.

Kjerstad went 0-for-4 with three strikeouts in last night’s 7-4 loss. Holliday was 1-for-4 with a run scored and two strikeouts.

Jorge Mateo is playing second base. Adley Rutschman is the designated hitter with James McCann behind the plate.

Rutschman was 3-for-5 last night and raised his average to .323 with a .785 OPS.

Ryan Mountcastle is starting at first base after delivering a pinch-hit single last night. He replaced Ryan O’Hearn, who had a two-run double and walked twice.

ANAHEIM, Calif. – Outfielder Heston Kjerstad, officially activated earlier today, is in tonight’s starting lineup for the Orioles batting eighth in right field. 

Ryan Mountcastle, who missed last night’s game with a sore left knee, could be back in that lineup very soon.

“Ryan is way better today,” manager Brandon Hyde said this afternoon in the visiting dugout. “He will definitely be available if we need him.”

As for Kjerstad, who is ranked as the No. 29 prospect by MLB Pipeline and No. 42 via Baseball America, he was tearing it up in 21 games with Triple-A Norfolk. He was batting .349/.431/.744/1.175 with four doubles, 10 homers and 30 RBIs. He went 8-for-16 his last four Tides games with three homers.

“Off to an unbelievable start in Triple-A. Huge power numbers,” said Hyde. “Hitting the ball hard to all fields. Just want him to come up here and try and contribute. We have a good lineup, but Heston has big-time power, so hopefully he can impact us offensively."

ANAHEIM, Calif. – As the Orioles face lefty Reid Detmers (3-0, 1.19 ERA) in tonight’s series opener with the Angels, they will be a missing a couple of key right-handed bats.

At least to start the game.

First baseman Ryan Mountcastle is dealing with knee soreness and outfielder Austin Hays went on the 10-day injured list with a left calf strain this afternoon.

The Orioles were seeing some positive signs with Hays’ bat. He is just 5-for-45 for the year, but had some loud outs recently and produced two hits his last four at-bats.

But any further progress will have to wait.

KANSAS CITY – Corbin Burnes tried to turn away from a hard one-hopper, felt the ball slam off his right hip, scrambled to retrieve it, failed on his first attempt and threw out the runner by a hair.

This was one batter into his start.

Burnes waved off manager Brandon Hyde and head athletic trainer Brian Ebel as they began walking to the mound. Like he knew that he wouldn’t be the starter knocked out early.

The Orioles sent 12 batters to the plate in the second inning and scored seven runs against Royals left-hander Cole Ragans, the same pitcher who blanked them on one hit in 6 1/3 in Baltimore. The same pitcher with the 1.93 ERA.

A relaxed-turned-tense 9-7 win at Kauffman Stadium improved the Orioles to 13-7 and ran their sweepless streak in the regular season to 98 series. The offense was stagnant last night until Adley Rutschman’s grand slam in the seventh, but it took good care of Burnes.

After a 7-4 win over the Minnesota Twins Monday at Oriole Park, in a game in which the Orioles never trailed, they host Minnesota again tonight with a chance to win this series. 

The Orioles (10-6) are on a pace to win 101 games, matching their 2023 total, at this early stage of this season. The O’s begin play today 1 1/2 games behind the Yankees for the American League East lead. They are 6-4 at home and 5-1 in series-opening games.

The Orioles hit three homers last night. They have hit nine in their past three games, 14 in the last five games and 24 on the season. That is a total that leads the AL and is one behind the Los Angeles Dodgers for the major league lead. The Birds average 1.5 homers per game, second in the majors to Milwaukee's 1.6

The Orioles hit two or more homers eight times this season and they are 7-1 in those games.

The Baltimore offense is starting to pick up. In winning five of their past seven games, the Orioles have scored 42 runs while hitting 15 homers. In those games the team batting average is .283 with a .343 OBP, a .504 slugging and .847 OPS.
