Tampa Bay will look to sweep the season series from Pittsburgh for the first time when the teams conclude a home-and-home set.
The Lightning have outscored the Penguins 18-3 in winning the first three meetings, including a 9-0 rout on Nov. 8.
Tampa Bay is 22nd in the league on the power play (14.2 percent), but has converted on 27.7 percent of its power-play opportunities against Pittsburgh.
The Lightning scored three power-play goals on Tuesday and went on to beat the Penguins 6-2 in Pittsburgh for their ninth win in 13 games.
Tampa Bay concluded a four-game trip with seven of a possible eight points to increase its lead in the Southeast Division.
“It was an unbelievable road trip with a lot of travel,” Kubina said. “It was a very tough road trip, but we’ve been playing great the last couple of weeks.”
Sydor, who will man the point, has 39 power-play goals and 172 power-play assists in his career.
“Darryl Sydor is the top four defenseman we have been searching for for quite some time now,” Tampa Bay general manager Jay Feaster said. “He will bring veteran leadership and significant playoff experience to our hockey club as he has already played more than 900 NHL regular-season games and almost 100 Stanley Cup playoff games at the age of 31.”
Pittsburgh’s loss on Tuesday was its seventh straight and ninth in 10 games.
Goalie Marc-Andre Fleury made 33 saves while under constant pressure, but still lost for the 11th time in 12 decisions. He has allowed at least four goals in six consecutive games.
“It’s pretty tough,” Fleury said. “Obviously, everybody wants to win.”
