Brouwer gave the Capitals a 3-2 series lead with his second goal of the playoffs, beating Tim Thomas over the glove with a wrist shot with 37 seconds left on Benoit Pouliot’s slashing penalty.
The Capitals can wrap up the best-of-seven series at home today.
The Bruins have been in this predicament before. They trailed the Vancouver Canucks 3-2 last year in the Stanley Cup finals, then won the last two games on the road to capture their first title since 1972.
PANTHERS 3, DEVILS 0
In Sunrise, Fla., Kris Versteeg scored a goal and set up another, Jose Theodore made 30 saves for his second playoff shutout, and Florida beat New Jersey to move a win away from its first series win in 16 years.
Scottie Upshall also scored for Florida, which leads the Eastern Conference first-round series 3-2. The Panthers’ last series victory came in the 1996 East finals, and they’ll have two chances to snap that drought.
Tomas Kopecky was credited with an empty-net goal with 34 seconds left, after Ilya Kovalchuk impeded his clear path to the net.
Martin Brodeur made 30 saves for New Jersey, which plays host to a win-or-else Game 6 on Tuesday.
SENATORS 2, RANGERS 0
In New York, Craig Anderson stopped 41 shots to make Jason Spezza’s first-period goal stand up, and Ottawa pushed top-seeded New York to the brink of elimination by winning in Game 5.
The Senators, the No. 8 seed in the Eastern Conference, have won two in a row and will have a chance to knock out the Rangers on Monday in Ottawa. If New York can stay alive, the deciding Game 7 would be back at Madison Square Garden on Thursday.
Since New York took a 2-0 lead in the first period of its 3-2 overtime loss in Game 4, Anderson has gone 116 minutes, 32 seconds without allowing a goal.
BLUES 3, SHARKS 1
In St. Louis, Jamie Langenbrunner and David Perron scored in a 45-second span in the third period, and the Blues woke up in time to put away San Jose and wrap up the first-round series.
Brian Elliott made 26 saves, and Andy McDonald ended all doubt with an empty-net goal in the final minute. St. Louis won a playoff series for the first time in a decade against a franchise that reached the conference finals the past two years.
