BOSTON -- Derek Roy almost won the game in overtime, but he did win it in the shootout.
The St. Louis Blues center, who scored a goal in regulation and sent one off the crossbar in overtime, scored in the fourth round of the shootout to give the Blues a 3-2 decision over the Boston Bruins Thursday night.
Roy was the second St. Louis player to beat Boston goaltender Tuukka Rask in the shootout, as the Blues moved to 15-3-3 on the season, 6-2-1 on the road.
The Bruins got a shootout-opening goal from center Patrice Bergeron against Jaroslav Halak, but the goalie, who made 29 saves during the game, was successful on the next three to improve to 18-15 lifetime in shootouts.
The Bruins, the Eastern Conference leaders, are 6-1-2 in their last nine games.
Rask, who made 24 saves, fell to 13-11 lifetime in shootouts.
Center Gregory Campbell scored his first goal of the season and left winger Carl Soderberg scored his third for Boston, and centers Roy (No. 6) and David Backes (No. 9) scored for the Blues in regulation.
Both teams had major chances in the overtime, with Roy hitting the crossbar on a breakaway and Soderberg, also in alone, stopped by Halak with 10 seconds left.
The Bruins, playing without injured defensemen Dennis Seidenberg and Adam McQuaid, had three rookies, including the NHL debuting Kevan Miller and 20-year-old second-year man Dougie Hamilton, on defense.
The teams traded goals in each of the first two periods. St. Louis defenseman Ian Cole was wiped out trying to carry the puck out, leading to Campbell's goal, and Rask whiffed badly on the tying goal by Roy, just 31 seconds later.
In the second period, Backes tipped in defenseman Kevin Shattenkirk's wrist shot from the point toi make it 2-1. The Blues then left Soderberg alone in the slot and center Maxim Lapierre didn't go down to try to block the shot that tied the game 2:37 after the Blues had taken the lead.
Each team killed a power play in the third period, when the only two penalties of the game were called.
Shattenkirk, who played for Boston University, picked up his 14th assist of the season on the Backes goal, the 100th of his NHL career.
NOTES: While D Adam McQuaid missed his sixth game with a hip and groin injury that's improving, fellow D Dennis Seidenberg suffered a lower-body injury on his first shift on Tuesday night in New York and also was out. "As far as tonight, he's not in," coach Claude Julien said before Thursday's game. "He's day to day and he's working out. It's probably one of those situations, I would put it, more or less, could be seven days, maybe less." ... D Kevan Miller made his NHL debut for Boston. ... The Blues go home to face the Dallas Stars on Saturday and the Bruins continue their homestand with a Saturday matinee against the Carolina Hurricanes. ... The Bruins, celebrating their 90th year, honored different decades at home games. On Thursday, it was the 70s as legendary defenseman Bobby Orr, who led the Bruins to the Stanley Cup in 1970 and '72, dropped the first puck.
