Dayne St. Clair screamed and stomped in the first half against FC Cincinnati on Wednesday.

The goalkeeper’s acts were warranted as defenders in front of him let the Loons down in a 2-1 loss at Allianz Field.

MNUFC (11-12-6, 39 points) had a two-game winning streak end, while defending Supporters Shield winner Cincinnati (17-8-4, 52 points) became the first MLS team with 10 road wins this season.

“We got ourselves into a position and we set up in such a way that those are the types of goals that we certainly shouldn’t have conceded,” Minnesota United coach Eric Ramsay said. “We showed some naiveté, particularly on the second goal to open up at a point in which we really didn’t need to.”

The Loons’ problems started midway through the first half.

MNUFC center back Michael Boxall allowed Yuya Kubo to go around him, but St. Clair made a diving fingertip save in the 29th minute. But five minutes later, Kubo outraced Micky Tapias and slotted a shot past St. Clair for a 1-0 lead.

St. Clair shot an arm up in frustration.

Then Bongi Hlongwane jogged back and allowed MLS MVP Luciano Acosta to get a shot on goal that was saved.

St. Clair yelled in exasperation.

That was followed by Hlongwane, Jefferson Diaz, Boxall and Tapias allowing runners in behind and Luca Orellano to cut across the field and score just before halftime. The deficit doubled in stoppage time.

“Sometimes a little shake-up kind of gets things moving forward,” St. Clair, who made three saves, said about his demonstrative efforts. “In some of those moments, I think, it would have prevented some of those long runs. Obviously I know I’m not doing the runs and I can respect that. Those runs are longer, but I try to organize so we can do the work earlier and it’s not a 50-yard sprint for these guys.”

After falling into a two-goal hole, Ramsay pulled out Hlongwane, Joaquin Pereyra and Carlos Harvey at the half, bringing in Tani Oluwaseyi, Wil Trapp and Sang Bin Jeong.

The Loons got back in the game when Orellano was called for a penalty with an apparent kick to Jeong’s head in the 18-yard box. Kelvin Yeboah converted from the penalty spot to make it 2-1 in the 55th minute. It was the new Italian forward’s third goal in three PKs this season.

Substitute forward Teemu Pukki nearly scored an equalizer in the 88th minute, but the Finn’s curling shot hit the corner of the goalposts. Pukki had another attempt but Roman Celentano made a save late in stoppage time.

The Loons’ best scoring chance came in the 20th minute when Pereyra had a breakaway with only the goalkeeper standing in his way. Instead of passing to an open Hlongwane, his shot was saved by Celentano.
