Barnsley manager Neill Collins hopes his side learn from their mistakes in the second half after they held off a fight back from Port Vale to win 3-2.
Adam Phillips opened the scoring before John McAtee added a quickfire brace, including a stunning strike from 35 yards for his second, to make it 3-0 after 37 minutes.
But Vale fought back after the break, with Ethan Chislett and Jack Shorrock both finding the net to make the scoreline much more respectable.
Victory keeps the Tykes in seventh spot in the League One table, two points outside the play-offs.
However, Collins believes his team should have put the game to bed and pinpointed a good chance for Herbie Kane, which was well saved by Connor Ripley just moments before Chislett earned Vale a lifeline in the 72nd minute, as an opportunity to do that.
“In the first half, I thought we were outstanding,” he said.
“I thought the quality of our goals was excellent, I thought we looked a real threat, I thought we looked comfortable defensively.
“So everything that was probably good about the first half was negative about the second, particularly the last 20 minutes.
“I thought we started a bit slow coming out in the second half, then we had a little period where we looked like a threat again and we probably should have made it four when Herbie Kane goes through.
“Port Vale got their goal and we had to make certain changes – some we made decisions on and some were forced.
“And I thought once they got their tails up, we struggled to cope with it.
“But I can’t take anything away from a great three points. I think we tend to have games like this in the Christmas period, and hopefully we learn from it.”
Defeat for the Valiants brought their three-match unbeaten league run to an end and saw them drop one place to 16th.
Boss Andy Crosby was left to rue an extremely disappointing first-half display, but was pleased with how his side responded.
“What was happening in that first half, we looked devoid of anything,” he said.
“The second half reaction is more like I want us to be.
“We played with pride, we played with enthusiasm, we played with quality.
“I can’t mask over that first-half performance and it’s something that I have to apologise to the fans for, because it was really poor.
“There’s a number of things – if you don’t track runs into the box, if you don’t defend balls into your box, you’re going to get hurt because of the quality of the opposition.
“They’ve obviously got a number of really good attacking options. They’ve got a good team. That’s why they are where they are in the league.
“And when you’re giving that much space and freedom to play, they’re going to hurt you.”
