PRAGUE –The Bruins have let sloppy play define the first two periods of their 2010-11 season, and as a result find themselves trailing the Coyotes, 4-0 heading into the third period. For a team that didn’t have to play from behind much a large chunk of the time in the preseason, it will be interesting to see how they respond.
The Coyotes potted their second goal of the game at 1:59 of the period when Tuukka Rask , a down and a bit deep in his net, was beaten top shelf on a rebound by Phoenix winger Taylor Pyatt. Daniel Paille  later gave away a puck in the offensive zone to a flying Scottie Upshall, who walked in on Rask and beat him low stickside. Then, with 16.1 seconds remaining in the period, Eric Belanger took a Ray Whitney pass in across the net and converted it into the Coyotes’ fourth goal.
Tyler Seguin  logged the most first-period ice time for the Bruins, but after two periods is a minus-two. The only player with a worse rating would be Matt Hunwick, who was moved off his pairing halfway through the period. Dennis Seidenberg  is now skating with Mark Stuart .
