It was a rare game for the Orioles — especially the post-trade deadline Orioles — in which everything seemed to go right.

They pitched well. They hit and ran in different situations. The defense, even with a hodgepodge center field, managed all the plays it needed to.

And even a two-hour, 18-minute delay forcing them to go to their bullpen for the last 3 2/3 innings didn’t ruin it as the Orioles beat the Seattle Mariners 5-3 Thursday to win the series at Camden Yards.

It doesn’t change much for an Orioles team that’s 55-66. But beating a playoff contender like the Mariners is one of the few accomplishments this team has left to celebrate.

The Orioles’ runs came off fundamental plays. Jordan Westburg took advantage of a wild pitch to score the first. Then Ryan Mountcastle and Daniel Johnson executed a double steal for the second. A single from Jeremiah Jackson — who also had a great throw in the first inning from right field to get the runner out at second — brought in the third.

After all, a struggling offense has to take advantage of anything it can.

“I don’t think we have much of a choice,” interim manager Tony Mansolino said.

Two more runs scored in the fifth, off a double from Gunnar Henderson and a sacrifice fly from Mountcastle. All the while, Tomoyuki Sugano held the Mariners to just two hits in five shutout innings. His ERA is down to 4.13, and he has the opportunity to end the season under 4.00 if he continues this stretch.

“Every pitch was effective and it went according to game plan, so it was good,” he said through interpreter Yuto Sakurai.

Then the rain started. By the time Sugano came out for the top of the six, it was nearly a downpour.

He got one out, but then Josh Naylor singled. Facing Julio Rodriguez, Sugano stepped off multiple times. He was assessed an automatic ball as he tried to dry his hand with the rosin bag in his back pocket. He didn’t feel he had a choice.

“If I had thrown another pitch, I wasn’t sure where it was going to go,” Sugano said.

Then Rodriguez asked for time, and both players started looking into their dugouts, arms raised, confused that play was continuing. Mansolino went out to talk to the umpires, also confounded by what was going on.

“When our pitcher has to step off the mound twice because he can’t see the plate because the rain is in his eyes so bad, it is the responsibility of the manager to go out there and state our case as to why that’s not a good situation for our team, and it wasn’t,” he said. “I didn’t love the situation as a whole.”

Eventually, the call was made and the tarp was brought out, but by this point the infield had been flooded. A hurried attempt to put the tarp out didn’t do much to stop the deluge.

Over two hours later — after multiple attempts to clean up the infield — Rodriguez finally stepped back into the box with the count 1-1, except it was against Rico García. Sugano’s day, because of the delay, was long done. Had it not rained, he would have had at least one more inning in him.

Four pitches after play resumed, Rodriguez took García’s high fastball to right-center field for a two-run homer. The hundred or so remaining Seattle fans, who had taken advantage of the now open seating policy to move behind the Mariners’ dugout, chanted his name.

A 5-0 lead was down to 5-2.

But Keegan Akin and Kade Strowd got through the seventh and eighth. Dietrich Enns allowed traffic, loading the bases with just one out, but did enough to secure the win. It was Enns’ first save since Sept. 20, 2021.
