BOSTON — The last time the Boston Red Sox won 15 straight games, Ted Williams was putting up an MVP season in 1946 and leading them to an American League championship.

On Wednesday, the Red Sox matched that streak from 80 years ago, beating the Baltimore Orioles 6-3 in the opener of a doubleheader.

“I’ve read some stuff. I know Ted Williams was around back then, so I’m aware of the year and how long it’s been,” interim manager Chad Tracy said. “It’s cool that they’ve accomplished something great.”

The streak finally ended Wednesday night, however, as Baltimore scored four runs in the first inning on its way to a 5-1 victory.

When the afternoon game was over, the Red Sox took a little more time than usual on the field to soak it in as The Standells’ song “Dirty Water” played in the background like it does after each victory at Fenway Park.

They also enjoyed the moment in the clubhouse.

“Oh, yeah, absolutely between the staff. We were realizing the guys were going crazy in the locker room — they always do — but even more emphasis right now with what we’re going through,” Tracy said. “Everybody enjoys it, for sure.”

Boston fired manager Alex Cora after a 10-17 start and seemed to be in for a long season. The Red Sox were 37-48 and last in the AL East on July 1. Now they’re in third place, and they hold an AL wild-card spot.

Tracy is the first manager since the 19th century to lead a team to a winning streak of 15 games or more who didn’t start the season in the job, according to MLB.

Boston took a 4-0 lead in the first inning of the opener, and starter Jake Bennett held the Orioles to three runs over 5 2/3 innings.

With a 6-3 lead after six innings, Caleb Durbin, who hit a tiebreaking homer in Monday’s win over Baltimore, started thinking about how many outs were left.

“I think in the seventh inning, I’m counting them down a little bit,” he said, smiling.

After the final out, left fielder Jarren Duran said he was able to appreciate the cheering crowd when he met with center fielder Ceddanne Rafaela and right fielder Wilyer Abreu.

“When I get to go see (them), I take a look around and I get to enjoy that moment, that’s always fun,” he said.

With the organization in its 126th season, the streak has more meaning for some.

“You look back at it and think about where you’re doing it and how long this franchise has existed. It’s been incredible,” Durbin said. “It feels great. One win closer to 16 to break it. I’m just glad we’ve got another one to play today.”

Orioles manager Craig Albernaz, who grew up watching the Red Sox about 45 miles away in Fall River, Massachusetts, showed his respect.

“I mean, a 15-game heater is really impressive,” he said. “You know, its tough to win one game in the big leagues, and them going 15 straight, it’s really impressive.”

In the night game, rookie pitcher Eduardo Rivera couldn’t make it out of the first inning, allowing four runs on three hits and two walks. Brayan Bello took over with two outs and worked 5 1/3 scoreless innings, but the Red Sox managed just five hits against Kyle Bradish and three relievers.

Boston’s lone run came in the fourth inning on a double by Willson Contreras and a single by Masataka Yoshida.
