If you thought Wednesday night’s extra-inning loss felt like a momentum-killer, your instinct was right on the money.

The Red Sox’s feast-or-famine season continued on Thursday, as did their unfortunate habit of making losing teams look like well-oiled winning machines. The Colorado Rockies, for example, lost eight in a row after winning the series at Fenway Park last week.

And after taking the first pair of the 4-game set in dominant fashion, the Red Sox lost 6-0 to the Twins, with a complete-game shutout capping off the series split.

Every time they seem to turn a corner, they turn back again.

The Twins teed off against Justin Garza and Brandon Walter, taking an early lead they’d never relinquish.

Garza opened the game (technically his first career MLB start), and allowed three earned runs on four hits. Carlos Correa and Byron Buxton got Minnesota on the board in the first with a pair of over-400-ft solo home runs.

Making his major league debut, Walter struggled early on, but ultimately settled in and held down the fort. He allowed struck out two, walked three, and allowed three earned runs on six hits (including Buxton’s second homer of the day). His performance was mixed bag, but three of his frames were scoreless and his 6 1/3 innings is the third-longest debut by a Red Sox pitcher in this century.

But the biggest story of the day was Joe Ryan, who pitched the first Twins’ complete-game shutout since June 2018, and his organization’s first against the Red Sox since 2002. Coincidentally, it was the first time the Red Sox were the victims of a complete-game shutout since they were no-hit by Sean Manaea in 2018.

Thursday came pretty close to being a no-hitter, too.

Through three, Minnesota’s starter had a perfect game going. Through six, a 1-hit shoutout.

Justin Turner broke up the perfecto, but the Red Sox couldn’t get anything going. They collected just three hits in the game, none for extra bases, and Ryan didn’t issue a single walk.

Having only thrown 82 pitches through seven, Ryan returned for the penultimate inning. Other than David Hamilton’s first career major-league hit, the Twins starter breezed through the eighth, too, and set a new career-high in shutout innings.

Back out for the ninth, he got the Red Sox to go 1-2-3 for the sixth time, dispatching the visiting team without protest.

Ryan had faced the Red Sox three times before, and they’d collected nine runs on 19 hits (two doubles, four home runs) against him. He’d allowed at least one earned run in 12 of his 14 starts this season, and was coming off giving up a season-high six earned runs to the 32-41 Detroit Tigers.

So, of course, he had a career day.

The cherry on top is that he was the Tampa Bay Rays’ seventh-round pick in 2018, when Chaim Bloom was their senior vice president of baseball operations.

In a crucial stretch when they have opportunity to make up ground, the Red Sox seem incapable of making any progress they don’t immediately undo. Four games after arriving in Minnesota, they depart with an identical winning percentage and place in the standings, last.

Next, they’ll head to Chicago, for a three-game set against the White Sox, who own a losing record in their own ballpark.
