With the fewest regulation losses in the NHL, the Boston Bruins have had little issue with their opposition this season, sans one notable exception.Perhaps improbably, the cellar-dwelling Detroit Red Wings have a chance to win their sixth straight game over the Bruins when they visit Boston on Saturday afternoon. The Red Wings, with an NHL-low 14 wins, have beaten the Bruins twice in Detroit this season — 4-2 on Nov. 8 and 3-1 last Sunday.Now the season series shifts to Boston, where the Bruins are 20-2-9. The teams will meet again at TD Garden on March 24.The Bruins enter Saturday’s contest having won seven of eight, the lone loss being the setback at Detroit. Boston had a 40-20 advantage in shots in that game but couldn’t solve Jonathan Bernier, who made 39 saves in net.”Give Detroit credit for winning the hockey game, but I don’t think they were the better team,” Bruins coach Bruce Cassidy postgame said.The Red Wings have rarely been the better team of late, losing 12 of their last 14 games (2-11-1). But when it comes to facing Boston, something seems to click.”It seems like they get excited to play us,” Bruins defenseman Torey Krug said. “For whatever reason, it’s a tough matchup for us.”Boston is coming off a 4-1 victory over the Montreal Canadiens on Wednesday in which star winger David Pastrnak completed his fourth hat trick of the season to surpass the 40-goal mark (41). He’s the first Bruin to accomplish that feat since Glen Murray scored 44 in 2002-03.Tuukka Rask also shined in net in the contest with 28 saves, improving to 13-0-6 at home this season. He has started Boston’s last three games while Jaroslav Halak recovers from an upper-body injury; Rask stopped 17 shots in Sunday’s loss at Detroit.
