Tampa Bay is 4-0 when holding a 3-1 series lead in the Stanley Cup Playoffs.
Here are 5 keys for Game 5:

1. Callahan might play, Vatanen won't

Lightning forward Ryan Callahan practiced Friday and
will be a game-time decision Saturday
. He has missed two games with an upper-body injury.
"He's progressing, so we'll re-evaluate him and see how he's doing [Saturday]," Lightning coach Jon Cooper said. "He's definitely a game-time decision."
Devils defenseman Sami Vatanen left Game 4 late in the first period with an upper-body injury after a check by Kucherov. Vatanen was not at practice Thursday, did not travel with the team and won't play.

2. Lightning's forward depth

In Tampa Bay's first two wins in the series, it received major contributions from their secondary lines; forward Alex Killorn scored three goals, centers Tyler Johnson (two goals, one assist) and Brayden Point (one goal, two assists) each had three points, and center Yanni Gourde had two points (one goal, one assist).
The top line of Kucherov, Steven Stamkos and J.T. Miller took over in Game 4, combining for the three goals with four assists. Kucherov has nine points (four goals, five assists), Stamkos has five points (one goal, four assists), and Miller has four points (one goal, three assists).

3. Vasilevskiy the closer

Lightning goaltender Andrei Vasilevskiy made 27 saves in Game 4, and the Vezina Trophy finalist will be trying to close out a Stanley Cup Playoff series for the first time.
Vasilevskiy has a 2.26 goals-against average and .937 save percentage in the series.

4. Special-teams battle

The Lightning's penalty kill was 28th in the NHL (76.1 percent) during the regular season but has improved in the postseason. The penalty killers have allowed three goals on 18 attempts (83.3 percent), and two of the goals came with the Lightning down two men.
"The power play has to figure it out," Devils forward Taylor Hall said. "We've had a good power play all season long (21.4 percent, tied for ninth in the NHL) and I think it's more of just a rut than something to panic about."
New Jersey did not allow Tampa Bay to score in five power-play chances in Game 4, but the Lightning are 5-for-14 (35.7 percent) in the series and 3-for-4 (75 percent) at home.

5. Muscle vs. muscle

The Lightning and Devils each turned up the physicality in Game 4 and were called for 13 penalties (seven against Tampa Bay, six against New Jersey). Game 5 is likely to be as physical; however, each coach stressed the need to play tough but smart and stay out of the penalty box.
"I think it's looked at as a physical series because you're looking at two teams that you don't really think play that way," Cooper said. "I think sometimes when it's not expected it seems like it's more than usual. But it's two teams that are trying to win, and that's why this series has been the way it's been."
