Now that was a bad loss.

At RFK. Riding a five-game unbeaten streak. Facing a wounded opponent. When the halftime whistle sounded, ending an unfulfilling 45 minutes, you just knew the match was going to turn against D.C. United. And right on schedule, the Revolution scored on a set piece — United’s weakness all season.

If you want to make the playoffs, you can’t lose at home to New England. And you can’t continue to drop points at RFK. (United is now 2-3-5 in the capital city and 0-2-4 in its past six at home.) There’s a long way to go in the MLS season and, thanks to the Eastern Conference’s instability, United should be able to stay in the race for awhile, but this one stings.

Credit to Matt Reis for a superb display of goalkeeping. Man of the match, without question. As for Charlie Davies, the badly missed penalty was the low point of a difficult evening. He didn’t move well. Maybe it was the thick air, maybe it was the mental strain of his scoreless streak (now four games). Whatever it was, he was laboring.

Ben Olsen was critical of his team’s finishing and wasn’t particularly pleased with the defending either. He also said playing consecutive matches four days apart in oppressive conditions took a toll.

“I was hoping we could recover physically, but there were some zombies out there at times.”

Expect many reserves in the lineup Saturday against Everton.
