TAMPA, Fla. (AP) -- Sidney Crosby put together another impressive performance, and the Pittsburgh Penguins needed each one of his big plays.
Crosby had three goals and an assist and Matt Niskanen scored a tiebreaking power-play goal with 18.6 seconds left, lifting the Penguins to a 5-4 victory over the Tampa Bay Lightning on Saturday night.
''It was evident today for us,'' Penguins coach Dan Bylsma said of Crosby's leadership.
Niskanen scored from the top of the left circle, with Crosby getting an assist.
''We kind of have a little bit of a plan on what we want to do on the power play, and for the most part we just kind of read and take what's there,'' said Niskanen, who scored for the first time in 22 games.
Crosby tied it at 3 with a knee-high re-direction of Rob Scuderi's shot 25 seconds into the third, and then put Pittsburgh in front when he scored from the right circle with 9:34 remaining. It was his eighth career hat trick.
''Pucks are going to be around there,'' Crosby said about playing near the net. ''It's not an easy place to go, and you're going to have to force yourself to go there as much as you can. Luckily there was some pucks around there, and I was able to get some good quality chances from there.''
Crosby has a point in all five games this season. It's his longest point streak to start a season since a six-game stretch in October 2005.
Alex Killorn got the equalizer for Tampa Bay with 3:02 to play. Valtteri Filppula, Steven Stamkos and Teddy Purcell also scored for the Lightning (3-2).
''I think that was an even hockey game,'' Tampa Bay coach Jon Cooper said. ''They got that last break at the end and capitalized on it.''
Brooks Orpik scored for the Penguins (4-1), who lost 6-3 Friday night at Florida.
Pittsburgh's Marc-Andre Fleury made 14 saves. Anders Lindback had 21 for the Lightning.
Orpik stopped a 110-game goal drought dating to Nov. 21, 2011, when he tied it at 2 just 1:50 after Stamkos' goal. The defenseman has 12 career goals in 636 NHL games.
Tampa Bay took a 3-2 lead on Purcell's knee-high deflection during a power play with 4:18 to go in the second.
Stamkos, coming off a hat trick in Thursday's 7-2 victory over Florida, gave Tampa Bay a 2-1 lead from the right circle at 5:11 of the second.
Crosby tied it at 1 with an in-close power-play goal 2:14 into the second.
''They, obviously, have some world-class players over there,'' Tampa Bay left wing Ryan Malone said.
