DETROIT (AP) -Pavel Datsyuk and Nicklas Lidstrom scored within the first 4 minutes Sunday and Detroit went on to beat Calgary 3-1, taking a 2-0 lead in their first-round series.
The Flames had five penalties, two of which led to Lidstrom's goal, in the first 8:13. The Flames seemed to unravel in the opening period, getting penalized twice for cross-checking in a 2-minute span.
Calgary's Dion Phaneuf scored a power-play goal early in the second period on a shot that was deflected and fluttered past Dominik Hasek's glove. The Flames went into the third within a goal because of that key score and Miikka Kiprusoff's 33 saves through two periods.
But they couldn't beat Hasek again.
Six minutes into the final period, Detroit rookie Valtteri Filppula followed up his goal-scoring debut in the playoffs with a goal off a rebound.
Game 3 is Tuesday night at Calgary.
Senators 4, Penguins 2
PITTSBURGH (AP) - Daniel Alfredsson scored twice during a second dominating Ottawa second period in as many days. The Senators made this lead stand, taking Pittsburgh's stars and its crowd out of the game in Game 3 of their first-round series.
The Senators seized back home-ice advantage - they have as many as two home games remaining in the series - by mostly controlling Pittsburgh's stars and getting two key goals from one of their own in Alfredsson.
Ottawa, rebounding from a 4-3 loss at home barely 24 hours before in which it twice squandered third-period leads, takes a 2-1 lead into Game 4 on Tuesday night. Game 5 follows in Ottawa on Thursday.
The Senators have been in control for all but 1 1/2 periods of the series, wining 6-3 in Game 1. Only this time - unlike Saturday, when the Penguins came back with three goals in the third period - they have the victory and the series lead to prove it.
