FOXBOROUGH — At the beginning of the week, Je-Vaughn Watson was without a goal in 14 starts with the New England Revolution.

After scoring in regulation and netting the decisive penalty kick in the Revolution’s win in the US Open Cup quarterfinals Wednesday, however, Watson strutted around the locker room before the team’s Saturday tilt against the Chicago Fire telling teammates he would score again. In the 85th minute of the game he backed up his words with a goal that led the Revolution to a 1-0 win at Gillette Stadium.

“That’s the thing with me,’’ Watson said. “Whenever I score one goal I just keep scoring. When I used to play in Jamaica, when I used to play in Dallas, whenever I score one goal I just want to get a few more so that’s the thing, I got the feeling before the game I was going to score, I told [Gershon] Koffie I was going to score, I told Kelyn [Rowe] I was going to score. It’s just a confidence that you have going into the game.’’

The Revolution were putting late pressure on the Fire via Diego Fagundez, who substituted for Scott Caldwell in the 58th minute, when Chicago goalie Sean Johnson conceded a corner kick after making three saves in two minutes.

Revolution defenseman Chris Tierney took the kick and Johnson came off his line to stop it, but missed the block, allowing Watson to knock a header into the net.

“I know Chris is going to hit the ball and I know, like, the perfect spot he’s always putting them in, so I was just focusing on getting the ball in the back of the net,’’ Watson said. “As soon as the keeper was coming out, he came in front of me, but I just, I keep my eyes on the ball kind of thing.

“From the get-go, I know he can’t get that ball so as soon as he came over I just headed it in the goal.’’

After scoring in regular time and on a penalty kick against the Philadelphia Union Wednesday in the Lamar Hunt US Open Cup quarterfinals, Watson started on the left side of the midfield for the Revolution, pushing Rowe up a line and Fagundez, who played 120 minutes Wednesday, into a substitution role.

Watson also played the whole game Wednesday, but coach Jay Heaps wasn’t worried about him tiring.

“He’s a gamer and I’ve asked him, how many times, ‘Are you tired?’ and he says ‘No, I’m good to go,’ ’’ Heaps said. “Look, Je-Vaughn is a guy where you write his name down on the game sheet you know exactly what you’re going to get. He’s going to leave it all on the field.’’

Watson has started 15 games at four positions in 2016. His goal Saturday was his first MLS goal of the season.

“I just keep fighting and at the end of the day it pays off because I’m trying to earn a spot on the team, so I have to do what I have to do,’’ Watson said.

New England entered the match in sixth place, the last playoff spot, in the Eastern Conference and four spots ahead of last-place Chicago which hasn’t won on the road all season.

As a matter of fact, with Saturday’s loss, the Fire’s MLS-record road winless streak now stands at 35.

On Wednesday, the Revolution bested the Union while Chicago topped the Fort Lauderdale Strikers to advance to the Open Cup semifinals. The teams will meet at Gillette Stadium on August 9.

Having played extra time and used mostly regular starters against Philadelphia, the Revolution seemed to be playing on tired legs.

They controlled possession for 55.3 percent of the game and took 11 shots on target to Chicago’s none, but most were of middling quality.

“Any time we felt like we found a little bit of a seam, we were a little bit off or we didn’t find the right pass,’’ Heaps said. “I think on a night when we’re a little bit fresher, we find those chances a little bit easier.

“I think tonight we had to wait for a moment, wait for a set piece and wait for a moment where we could get everyone to take a deep breath and commit to making a play and that’s what Je-Vaughn did.’’
