Corbin Burnes finished the first inning, shook his head in frustration - at least partly with the plate umpire’s strike zone but more at himself - and walked to the dugout. Catcher Adley Rutschman met him along the first base line and could have been invisible.

On a night that the Orioles optioned top prospect Jackson Holliday, the veteran right-hander needed his own reset before returning to the mound. Shea Langeliers homered on a first-pitch cutter with two outs, the fifth run surrendered by Burnes in the first inning this season. But Burnes regained control of his start and did his usual ace-like work. His troubles seemed to disappear.

Unfortunately for the Orioles, so did their slim lead. And that was the most frustrating part.

Closer Craig Kimbrel, trying for a 425th career save that would have tied him with Kenley Jansen for 5th place on the all-time list, failed to retire any of the five batters faced in the ninth, the only out coming on a play at the plate. He left with the bases loaded and the score knotted and Keegan Akin prevented the go-ahead run from crossing, but the Athletics won in 10 innings 3-2 before an announced crowd of 22,965 at chilly Camden Yards.

Jacob Webb let the go-ahead run score after a 5-2-5-3 fielder's choice removed the automatic runner. Brent Rooker doubled to left field to give Oakland the lead.

Jackson Holliday met with Orioles officials earlier today and was sent back to Triple-A Norfolk with a specific agenda. Areas of improvement were detailed. They just weren’t shared with everyone.

Executive vice president/general manager Mike Elias met with the media today for about 20 minutes and explained the club’s decision to option Holliday, baseball’s No. 1 prospect who went 2-for-34 with one RBI, two walks, 18 strikeouts and five runs scored in 10 games.

The inability to get hot at the plate was a prime factor, of course. No complaints about his defense at second base, a relatively new position. The Orioles will be facing another wave of left-handed starters, which would have put Holliday on the bench. And his struggles were harder for a contending team to overlook than perhaps the 110-loss group from the rebuilding days.

There isn’t a firm timeline for Holliday’s return, but he apparently won’t be rushed back to the majors at the first whiff of success.

“I want to emphasize that this is a kid that’s doing extremely well and is at the very infancy of his major league career,” Elias said. “I don’t know if anyone else from his age group or draft class, high school hitters, are even out of A-ball levels yet. I want to stress that he’s doing very, very well and way ahead of the curve. And this was a decision out of camp that was very borderline at the time. Got a lot of opinions. We ended up sending him down and he hit really, really well in Triple-A for a couple of series, about two weeks, and so we decided to call him up and see how the translation to the major leagues would go on a short-term basis, and what we have seen here and had seen led me to the evaluation and the opinion that he would benefit from going back and adjusting there rather than doing it here in real time.

Ramón Urías is starting at third base tonight with Jordan Westburg at second following the Orioles’ decision to option Jackson Holliday to Triple-A Norfolk.

Urías is batting ninth and Westburg is slotted seventh. Colton Cowser is in left field and batting eighth.

Ryan O’Hearn is the designated hitter.

Corbin Burnes is 3-0 with a 2.76 ERA and 0.920 WHIP in five starts. He’s never faced the Athletics.

Right-handed and left-handed hitters have registered a .208 average against Burnes in his career. Right-handers have a .612 OPS and left-handers have a .602 OPS.

Jackson Holliday is headed back to the minors.

The Orioles announced today that they’ve optioned Holliday to Triple-A Norfolk and selected the contract of outfielder Ryan McKenna.

Holliday made his highly anticipated major league debut on April 10 in Boston, but he couldn’t get onto a roll offensively. He went 2-for-34 with one RBI, two walks and 18 strikeouts in 10 games.

The hitless streak reached 13 at-bats before his single in the seventh inning on April 14 against the Brewers at Camden Yards. Holliday’s other hit came Wednesday afternoon in Anaheim with another single.

Baseball’s top prospect is getting a reset with Norfolk. The Orioles can explain later the timing of the move and potentially how long it could last.

The Orioles are refreshed after yesterday’s break, which the bullpen needed, and ready to host the Athletics for three games and dive back into division competition with four against the Yankees.

Eight of nine series will be outside the American League East before the Yankees come to town.

It could have something or nothing to do with the 16-8 record and eight wins in the last 10 games. This is a very good team, which falls way short of a hot take. Just stating the facts.

The Orioles will be in the playoffs. The only question is whether they’re still active in November. I’m not making any plans until the second week of the month.

On paper at least, they can only get better with injured pitchers returning, Jackson Holliday eventually being Jackson Holliday, other prospects ready for promotion, and one or more trades likely at the deadline.

The coincidence didn’t hit Ryan McKenna right away. He was in a brightly lit airport in Norfolk but also in the dark.

McKenna had no clue that Austin Hays strained a calf muscle and the Orioles needed an outfielder to replace him. He missed the news, which perhaps would have taken his mind in a direction that raised hopes for a return to the majors.

Instead, McKenna stood next to Heston Kjerstad when one of baseball’s top prospects received a phone call from Tides manager Buck Britton. Get back on a plane and head to Anaheim. The Orioles are calling you up.

“To be honest, I didn’t see the injury to Hays, so I wasn’t like fully aware of what was going on,” McKenna said this week.

“I love Heston, man. He’s such a good player. He’s going to be a good major leaguer for a long time, so I was super happy for him. He’s probably one of the guys that I’m closest to in the minor leagues. It was cool. He’s a solid player. Offensively, he outshines this league pretty dramatically.”

ANAHEIM, Calif. – As this game got into the middle innings today, it seemed Gunnar Henderson and Dean Kremer were battling for the O's top starring roles.

Henderson kept getting hits and driving in runs off lefty pitchers and Kremer kept getting whiffs and putting up zeros with his four-seamer and cutter.

It all added up to an Orioles 6-5 victory as they took a 6-0 lead and then held off the Angels. The Orioles win this series and complete a 4-2 road trip. They head home 16-8 and get ready to host the Athletics on Friday night.

The Orioles are now 3-1 in rubber match games and have won six of their eight series.

After Los Angeles cut a six-run deficit to 6-4 on Zach Neto's homer of Yennier Cano in the eighth and 6-5 in the ninth, closer Craig Kimbrel got the final outs as they held on to win.

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.

My mailbag didn’t make it to Anaheim. No direct flights. Refused to fly into LAX.

What am I supposed to do?

I emptied it at home. Let’s get to it, the latest sequel to the beloved 2008 original.

Same rules apply, which is very few. Closer to none. I like editing questions about as much as I like the middle seat on a Southwest flight. Your questions are crystal clear. I don’t need to enhance the clarity. Your style is fine, except for those skinny slacks that don’t go past the top of your ankles.

Also, my mailbag sticks your mailbag with the bar tab, and yours only had water.

ANAHEIM, Calif. – Maybe this was a reverse-lock game. A night after the Orioles moved into first place, they put their 15-7 record and three-game win streak on the line with right-hander Grayson Rodriguez and his 2.63 ERA on the mound. He had not allowed more than two runs in any start this year.

The Angels had scored just nine runs during a five-game losing streak, were 2-5 at home and their pitcher, right-hander Griffin Canning, began his night with an ERA of 8.05.

What could go wrong? O's would have this one, right?

Well, the Angels got a Mike Trout leadoff homer and kept swinging it with loud contact in the early innings off Rodriguez as they beat the Orioles 7-4 at Angel Stadium.

Down 7-0 in the fifth, the O’s pulled within three runs but took the loss. They are now 15-8 for the year and 7-4 on the road, and return Wednesday to the ballpark looking for a series win in the rubber match game.

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."

Heston Kjerstad will play his first major league game tonight since Oct. 1, starting in right field as the Orioles attempt to claim another series.

Kjerstad is batting eighth, nestled between third baseman Jordan Westburg and second baseman Jackson Holliday in a lineup featuring seven players that the Orioles drafted. An eighth, Grayson Rodriguez, is on the mound against the Angels.

A ninth, cleanup hitter Anthony Santander, was selected in the 2016 Rule 5 draft. Santander is the designated hitter tonight.

Ryan O’Hearn is playing first base with Ryan Mountcastle on the bench. Mountcastle didn’t play last night due to a sore left knee.

Colton Cowser remains in left field and has homered in back-to-back games.

The Orioles won again last night and are in first place in the American League East with a 15-7 record. Their 126 runs scored and .780 OPS lead the American League. Their 35 homers lead the majors.

And now, the mid-market rich get richer.

Outfielder Heston Kjerstad was recalled today from Triple-A Norfolk, bringing him back to the majors for the first time since the Division Series. Catcher David Bañuelos, activated yesterday from the taxi squad, was optioned to the Tides.

Kjerstad is the actual replacement for outfielder Austin Hays, who went on the 10-day injured list yesterday with a left calf strain retroactive to Sunday. He’s battering Triple-A pitching, hitting .349/.431/.744 with four doubles, 10 home runs and 30 RBIs in 21 games. He’s also drawn 12 walks.

The first promotion came on Sept. 14, with the Orioles selecting Kjerstad’s contract. He went 7-for-30 with a double and two home runs.

Austin Hays avoided the injured list for the past two seasons, a huge turn in his career after the litany of setbacks dating back to the minors. Much of it bad luck, like the sprained thumb in 2019 on a stolen base attempt after the Orioles optioned him from camp. A head-first slide that he’s done countless times, except he hit the bag wrong.

Hays had slashed .351/.385/.892 in 12 exhibition games, with three doubles, a triple, five home runs and 13 RBIs. But the Orioles wanted to continue his development in Triple-A following his ankle surgery the previous year and the sore shoulder that had interrupted his spring training.  

The toughness was never questioned. Hays played through a lot of pain. And he reached 500 career games while the Orioles were in Pittsburgh.

“He’s tried to be healthy all throughout the year,” said manager Brandon Hyde. “He’s done that the last couple of years as best as he possibly could.”

That’s why yesterday’s news seemed so cruel.

ANAHEIM, Calif. – After going 2,395 days between major league outings coming into this season, this time right-hander Albert Suárez had only a four-day wait.

He held Minnesota scoreless over 5 2/3 innings Wednesday in Baltimore – his first game in the majors since Sept. 26, 2017 – and was back out tonight for the O’s in their series opener in Los Angeles.

And he had another outstanding outing.

He also had another scoreless outing, again over 5 2/3 innings, as the Orioles beat the Angels 4-2 in front of 26,081 to start a three-game series.

The Orioles, who moved into first place in the American League East by a half-game over the Yankees, improved to 15-7 and to 6-2 in series-opening games. They are 7-1 their past eight games and 10-3 the last 13. 

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.

The calf soreness that removed Austin Hays from Saturday night’s game in Kansas City has landed him on the 10-day injured list.

Hays was diagnosed with a left calf strain, with the IL move retroactive to yesterday. He’s 5-for-45 with two RBIs.

The at-bats have improved of late, with a hit in each of his last two games and some loud outs.

Manager Brandon Hyde kept Hays out of yesterday's lineup. Asked later about Hays' status, Hyde said, "We're going to kind of see how he is tomorrow."

Hays hasn't caught a break since reporting to camp. He had a stomach virus in spring training and was under the weather in Pittsburgh.

Orioles infielder Jordan Westburg was named the American League’s Player of the Week after batting .478 (11-for-23) with a .913 slugging percentage, two doubles, a triple, two home runs, eight RBIs, a walk, five runs scored and a stolen base in six games.

Westburg led the majors in batting average and OPS (1.413), tied for the lead in total bases (21) and ranked second in slugging. He tied for the AL lead in RBIs and tied for third in on-base percentage (.500) and hits (11).

The Orioles are on an award roll with Colton Cowser winning it last week.

This is only the third time that the team’s had back-to-back recipients. Eddie Murray won it on Sept. 13-20, 1981. Don Baylor was honored on Aug. 10, 1975, followed by co-winners Jim Palmer and Ken Singleton on the 17^th.

Westburg is batting .457 (16-for-35) during a nine-game hitting streak. He’s batting third tonight in Anaheim, where the Orioles begin a three-game series.

KANSAS CITY – The late innings of Saturday night’s game backed the opinions of Orioles first base coach Anthony Sanders.

Working with the outfielders as the team’s instructor brings a broader appreciation of the group’s abilities.

A once-comfortable lead was slipping away when Colton Cowser, a late replacement in left field with Austin Hays experiencing some cramping in his calf muscle that could put him on the injured list today, threw out Kyle Isbel trying to advance to third base in the seventh inning on Maikel Garcia’s run-scoring single.

The Orioles led 9-7 in the bottom of the ninth and closer Craig Kimbrel retired the Royals in order, but after right fielder Anthony Santander charged Bobby Witt Jr.’s shallow fly ball and made a sensational diving catch.

Preventing the leadoff hitter from reaching was one of the biggest moments in the game.
