FOXBOROUGH — The timing was right for the Revolution to break their scoring slump Saturday night. After compiling scoreless streaks of four games and 374 minutes, the Revolution took a 2-0 win over the Colorado Rapids on a night dedicated to all-time leading scorer Taylor Twellman.

The Revolution (7-12-9, 30 points), ending a six-game winless streak, took the lead on a 12th-minute Juan Agudelo goal, the team’s first since a 4-1 loss at Toronto Aug. 6. Chris Tierney added a 49th-minute score as the Revolution attacked effectively in their second game since switching to a 4-4-2 formation.

Agudelo and Lee Nguyen combined up front, the Revolution missing Kei Kamara (Sierra Leone national team), against a Rapids team (11-5-10, 43 points) playing without former Revolution midfielder Jermaine Jones (injured), plus goalkeeper Tim Howard and three others on international duty.

The scheme also allowed Diego Fagundez and the other Revolution midfielders to take on playmaking roles in what Nguyen described as “free-flowing football.’’

Nguyen hit the post twice in the first half, on a 33d-minute penalty kick and a 41st-minute attempt off a give-and-go with Agudelo.

“That was the whole point of changing the formation,’’ Nguyen said. “Coaches wanted to put our possession players centrally and have them in the center of the field, Scotty [Caldwell] and [Gershon] Koffie keeping the foundation, the ball flowing left to right, and me and Juan finding those little pockets in between.’’

Agudelo finished to the far side of the net past Zac MacMath, the Revolution’s first goal since Teal Bunbury’s 88th-minute score against Toronto. The sequence began off a throw-in, Koffie and Nguyen playing a give-and-go, Koffie laying off for Agudelo.

Dillon Powers had chances to tie, one-timing a shot wide left (15th minute) and having a drive saved (18th) by Brad Knighton.

“A timely save,’’ Revolution coach Jay Heaps said. “It was the save you need in a game where we need things to go our way. If that goal had come back and now it’s 1-1, who knows what’s in the next moments? I thought that was huge and that kept our confidence up.’’

After the fans produced a 20th-minute chant in support of Twellman’s ThinkTaylor concussion awareness organization, the Revolution went back on the attack.

A Caldwell through ball sent Kelyn Rowe in alone, Rowe going down after slipping the ball under a diving MacMath. Nguyen, who had converted 11 successive penalty kicks, sent the shot off the right post, his first miss since Sept. 21, 2013 (2-1 win over D.C. United). Nguyen is 13 for 15 on penalty kicks since joining the Revolution in 2012, one better than the previous team record held by Shalrie Joseph (12 for 15).

Eight minutes later, Agudelo back-heeled to Nguyen­ on a give-and-go, Nguyen continuing past three defenders across the top of the penalty area, then sending a shot off the left post.

Tierney scored his second goal of the season and 10th of his MLS career after Rowe touched on to Fagundez, who ran into the penalty arc, then laid off for Tierney to launch a left-footer into the far side of the net.

The Revolution then began slowing the game down, controlling possession. But the Rapids threatened. In the 60th minute, Knighton tipped a Powers header over the bar off a Dominique Badji cross, and in the 78th minute, a close-range Liam Doyle shot was blocked by London Woodberry.

The Revolution remain at the bottom of the Eastern Conference in goals scored (31), but the two-striker setup could help them remain in contention for a playoff spot — they are 2 points behind D.C. United in the race for the final place.

“We’ve gone through a rough patch here recently and just not been able to convert on our chances,’’ Knighton said. “We put it all together and really showed what we’re capable of doing, and that’s a confidence thing and that builds with wins and shutouts.

“These guys are finishing balls in training, it’s just not converting in the game situations. Finally, we took our chances. We had multiple chances in the first half, and hit two posts, so the chances are there and the goals are starting to come now. So, hopefully we can right the ship and continue on the winning way.’’

Kamara and Je-Vaughn Watson (Jamaica national team) are expected to return for the Revolution’s game against Eastern Conference leader New York City FC next Saturday.

“We don’t have time to relish anything,’’ Heaps said. “Right now, we’re on to the next game.

“I’ve already written on the board in the locker room — NYCFC — we’re on to the next game.’’
