Thomas made 32 saves on the night, improving his record to 33-10-8.
After a scoreless first period, the B’s got second-period tallies from Zdeno Chara  and Johnny Boychuk . Nathan Horton  provided the Bruins with some extra breathing room in the third period when he beat Chicago goaltender Corey Crawford his 24th of the season.
The win brought the B’s within three points of the Capitals for second place in the Eastern Conference, as Washington lost in a shootout Tuesday. The B’s have played 76 games to the Capitals’ 77. Should the teams end up finishing the season with the same point total, the Bruins would likely hold the tie-breaker, as they currently have more wins in games determined in regulation.
WHAT WENT RIGHT FOR THE BRUINS
– Mark Recchi  now has 12th place on the list of career points all to himself. His assist on Johnny Boychuk’s goal gave him 1,532 points, breaking his tie with Paul Coffey. Recchi would need to play another season to get to Ray Bourque ‘s 1579.
– Thomas was in danger of giving up the league lead in goals against average a couple of weeks ago, but his play of late has given him some separation from Nashville netminder Pekka Rinne. Thomas has allowed just one goal over his last three starts, the second time he has had such a three-game stretch. The Bruins did an excellent job of clearing loose pucks in front of the net from the get-go Tuesday, greatly helping Thomas’ cause.
– The interesting story line of Michael Ryder ‘s healthy scratches could continue, as Paille has made good use of his spot in the lineup the last two games. Paille picked up a helper on Horton’s goal, getting the puck in front from behind the net.
– Don’t look now, but Johnny Boychuk has two goals in his last four games. Of course, he had just one goal on the season prior to his goal against the Canadiens last Thursday, so the chances anyone worries about his scoring touch aren’t very big.
WHAT WENT WRONG FOR THE BRUINS
– The Bruins did not have a power play the entire game. It was the eighth game that they have had one or zero power plays. Interestingly enough, they are 7-0-1 in those games.
– Shawn Thornton  left the game in the second period after getting cut above the eye and did not return. Bleeding from the face, Thornton shoved referee Don VanMassenhoven as he was passing the Chicago bench on his way off the ice, seemingly because Blackhawks were chirping from the bench.
– Another night of solid play but no production from the third line. Tyler Seguin  and Chris Kelly  had an opportunity on Crawford in the first period, but Seguin’s pass in front of the net was just out of Kelly’s reach. Seguin has just one goal over his last 15 games.
