Brandon Young had everything going for him tonight except offensive support.

That would come, too.

Young forced the Mariners to beat the ball into the ground, where he recorded eight outs through the fourth inning and 12 through the seventh. He struck out five, including three with his revamped splitter. He acted like a veteran unwilling to back down from a pitchers’ duel.

Needing a stopper with their losing streak at four games, the Orioles turned to Young and were rewarded again in a 7-2 victory before an announced crowd of 13,483 at Camden Yards. In his 22nd major league start and 10th this season, Young shut out the Mariners on two hits over a season-high seven innings. And a scoreless tie evaporated in the sixth on Pete Alonso’s leadoff home run against George Kirby.

Leody Taveras and Blaze Alexander added run-scoring doubles in the inning, Jackson Holliday broke open the game with a grand slam in the seventh, and the Orioles improved their record to 32-37 with a chance Thursday night to split the series.

“It was great to see,” Young said of the uprising. “Not surprised. Like I told this team earlier, we’re really good, and we know it, but I think to go toe-to-toe … Kirby’s a really good pitcher. He’s got some nasty stuff. It kind of lit a fire under me to keep it a low-scoring game for the team just to keep the team in it, knowing that we’re going to get a couple of runs here and there. And glad we did – three-spot here and a four-spot right after.”

Holliday connected off reliever Domingo Gonzalez with two outs to give the Orioles a 7-0 lead. He has three career slams, joining Brian Roberts as the only Orioles with that many among his first 25 homers.

“I knew they were attacking me with heaters kind of all night, and I was just trying to get one down in the zone to hit a line drive,” Holliday said. “Kind of got one over the middle of the plate and was able to, I guess, hit it out. But I kind of had a game plan of they’re going to throw a lot of fastballs and just got to be ready and be on time.”

Two of Holliday’s three slams have came on Bark at the Park. He isn’t dogging it.

“It feels like we’ve had a lot already this year, but I mean, I think every night should be Bark at the Park,” he said with a grin. “I don’t think there should be any rules. But it’s always fun.”

Young lowered his ERA to 3.04. He’s allowed five earned runs in his last four starts over 26 2/3 innings. He was removed tonight after 88 pitches, and the Orioles improved to 9-1 in his games.

“He’s been outstanding,” said manager Craig Albernaz. “Tonight was awesome, attacking the strike zone. This split was real again, that pitch is a great equalizer for him. But just the way he throws strike right now, and command the strikes on attacking with all of his pitches, getting the curveball going, the slider, and in both fastballs, yeah, was an awesome performance.”

Everyone can see Young taking the next step in his career. He hasn’t tripped.

“I think so,” he said. “Trying to stay present as much as I can, not trying to get too ahead of myself.”

“It’s been awesome,” Holliday said. “It’s been awesome to watch. B.Y. is an amazing guy, so it’s even more fun to watch him just go out there and dominate for, it feels like the past four or five times that I’ve seen him. It’s been a lot of fun.”

“I think it’s credit to him,” Albernaz said. “It’s tough, any player, make adjustments in season, and the pitching group has done a great job with BY, but BY has put in a ton of work, and to see him go out there and be really consistent with everything he does, his work in between starts, his prep work, and then ultimately what he does in the mound and what you see is a confident BY right now, and just attacking the strike zone.”

Young tied Shane Baz for most consecutive quality starts with four. Keeping the ball on the ground was a key tonight.

“I definitely think it worked, definitely helped out just getting some I think early contact, weak contact, especially to Jackson. A lot to Jackson,” Young said. “Wasn’t the intention, but I think it just had to do with the amount of splitters, curveballs, and kind of  just how we were attacking them.”

Young’s only going to get tougher as he refines the splitter.

“You can see some of the pitches, it still wasn’t coming out right, and then some were really good,” he said. “I think I saw one was like negative-five vert, and then others just coming out a little too soon and it’s kind of flying out on me. But yeah, I think the more I throw it, the more consistent it’s gonna be and the more confidence I can throw it to both sides, righties and lefties.”

Young retired 12 in a row after Cole Young singled with one out in the third. Kirby retired nine straight after Gunnar Henderson singled with no outs in the third, but Alonso sent a high 96.8 mph fastball 402 feet to right-center field.

Finally, a breakthrough.

Taveras led off the second inning with his sixth bunt single, but he was thrown out trying to steal while Holliday struck out. Tyler O’Neill followed with his second double in his last three at-bats going back to last night and was stranded.

O’Neill also doubled in the seventh after Holliday’s slam and is 7-for-24 since May 25. He has two multi-hit games this season, the other on April 7.

“He had a great swing last night, driving the ball to the opposite-field gap,” Albernaz said. “Kind of like we talk about with a lot of hitters, a right-handed hitter, when you drive the ball the other way to that gap means a lot going right. To see him do that again in his first at-bat and then get another double down the line, it’s awesome to see.

“He’s been working hard. I think everyone knows that he’s not the best version of himself right now but he’s been working hard the whole season to get back to show what he can do. The boys in that clubhouse and everyone sees the work he’s putting in. So, yeah, the guys were fired up to see T.O. get some results.”

The Orioles loaded the bases with no outs in the third on Sam Huff’s infield hit, Taylor Ward’s walk and Henderson’s single into center. They still couldn’t score. Alonso struck out, Colton Cowser flied to shallow center, Taveras struck out and the crowd booed.

Alonso began and ended Kirby’s streak of outs, and he took over the team lead with his 14th homer.

The Mariners scored twice against left-hander Grant Wolfram in the eighth. Wolfram walked only his second batter this season in 23 appearances.

The Orioles were 2-for-20 with runners in scoring position in the series before tonight and 4-for-31 during their losing streak. They went 4-for-13 tonight.

Leftover Albernez

Albernaz spent the bulk of his seven-minute pregame media scrum talking about Samuel Basallo’s absence again from the lineup, his relationship with the young catcher and the disappointments and support received in first season as a major league manager.

“Sometimes you have to make decisions where it’s not popular decisions, but it’s ultimately what you feel like is best for the team and the players moving forward. And that’s something that I don’t take lightly,” Albernaz said.

“In Sammy’s case and to Sammy’s credit, he’s ready. Like yesterday’s at-bat against (José A.) Ferrer was outstanding. It’s a really tough lefty and his job, what he was trying to do, was to make contact and move the ball forward, which he did, and it was a great at-bat for us. Sammy’s such a great player, smart kid. Everyone talks about the talent and the physical tools are there, but he’s such a bright kid, smart kid, especially for 21 years old and being a catcher. It’s a lot on his plate.

“With Sammy, we’re playing the long game with Sammy and we’re here to love and support on him.”

Albernaz also was asked about his relationship with control owner David Rubenstein and president of baseball operations Mike Elias. Albernaz didn’t shield himself from the Orioles’ sub-.500 record and residency in the lower tier of the division.

“All of them have been great,” he said. “Mike has been awesome to work with. David’s been awesome, as well. And they all want what’s best for the guys that are in that clubhouse, and ultimately for the city and to win. And right now, I’m not holding up my end of the bargain, because I’m judged on wins and losses and right now we’re not performing the way that I want, and that’s ultimately on me and I know that. I take full accountability for that.

“But when it comes to David and Mike and everyone that’s been above me in leadership, they’ve been outstanding to work with. They’ve been awesome, supportive, every step of the way.”

Helsley update

Closer Ryan Helsley begins an injury rehab assignment Thursday with Triple-A Norfolk.

Helsley made it through his live batting practice sessions without experiencing any discomfort in his right elbow. He hasn’t pitched for the Orioles since April 28.

Helsley still leads the club with seven saves.

Tromp returns to organization

The Orioles have signed catcher Chadwick Tromp to a minor league contract and assigned him to Norfolk.

The Braves designated Tromp for assignment after he went 5-for-25. He appeared in six games with the Orioles last summer and went 3-for-16 with a double and home run.

Albernaz has a relationship with Tromp dating back to their days with the Giants.

Norfolk could use an extra catcher with Huff on the Orioles’ roster and Silas Ardoin on the taxi squad. And the major league club has a murky catching situation with Basallo and Adley Rutschman out of the lineup for three consecutive games. Rutschman hasn’t played since Sunday.

“He wanted to Kirk Gibson it,” Albernaz said. “He felt good after the workout, so we’ll see how he feels after he sleeps tonight and wakes up tomorrow. But, yeah, it was an encouraging sign.”
