NYR-OTT -- STL-NSH Playoff buzz 5-2

Welcome to the 2017 Stanley Cup Playoff Buzz, your daily look at the stories impacting the 2016-17 postseason. The playoffs continue Tuesday with two games. NHL.com writers covering the playoffs will be checking in throughout the day to give you latest news, including from the sites of the two games. Here is the playoff news for Tuesday:

5:23 p.m.
Oilers must improve faceoff performance

The Edmonton Oilers may have a 2-1 lead in the best-of-7 Western Conference Second Round series against the Anaheim Ducks, but they have struggled to keep up in the faceoff circle.
After finishing last in regular-season faceoff win percentage (47.0), the Oilers have won only 81 of 200 faceoffs over the first three games (40.5). They know they'll need a more concentrated effort to defeat the Ducks in this series.
Anaheim is unlikely to have right wing Patrick Eaves for Game 4 on Wednesday (10 p.m. ET; NBCSN, SN, TVA Sports). Eaves, who sustained the injury early in the third period of Game 3 on Sunday, didn't skate when the Ducks practiced in Kelowna, British Columbia on Tuesday.
The Ducks will also be without defenseman Kevin Bieksa, NHL.com's Lisa Dillman reports. Bieksa is out until late in the series with a lower-body injury.
Oilers captain Connor McDavid said Tuesday he was honored to be named a finalist for the Hart Trophy with Columbus Blue Jackets goalie Sergei Bobrovsky and Pittsburgh Penguins center Sidney Crosby. McDavid won the NHL scoring title with 100 points (30 goals, 70 assists) in the regular season.
"It's a credit to my teammates and being able to play for this great team and being able to play with all these great players," McDavid said.

Here's the scoop on the two postseason games set for Tuesday:
Ottawa Senators at New York Rangers (7 p.m. ET; NBCSN, CBC, TVA Sports) -- There's a chance Rangers left wing Tanner Glass will replace Pavel Buchnevich in the Game 3 lineup to make his debut in the Eastern Conference Second Round against the Senators.

. Senators left wing Clarke MacArthur
will be in the lineup
after leaving Game 2 on Saturday with an upper-body injury, according to staff writer Mike G. Morreale.
St. Louis Blues at Nashville Predators (9:30 p.m. ET; NBCSN, SN, TVA Sports) -- There's no place like home in the postseason for the Predators, who have won seven straight playoff games at Bridgestone Arena dating back to Game 6 of their Western Conference First Round series in 2016 against the Anaheim Ducks. Nashville has allowed a combined four goals in three home wins this postseason. Blues coach Mike Yeo is expected to make a few lineup adjustments with St. Louis trailing 2-1 in the best-of-7 series. Forwards Zach Sanford and Magnus Paajarvi are likely to play. Correspondent Robby Stanley has

Senators look to match Rangers' desperation

Ottawa Senators coach Guy Boucher said they will have to manufacture their desperation superficially because the urgency will clearly be on the New York Rangers' side in Game 3 of the Eastern Conference Second Round on Tuesday (7 p.m. ET; NBCSN, CBC, TVA Sports).

The Rangers lineup could change with forward Tanner Glass potentially replacing Pavel Buchnevich, although coach Alain Vigneault would not confirm anything Tuesday morning. What we do know for sure is that the Senators lineup will not change, meaning forward Clarke MacArthur (upper body)
will be in the lineup

Senators and Predators look to take commanding leads

The Ottawa Senators have an opportunity to take a 3-0 lead in their best-of-7 Eastern Conference Second Round series against the New York Rangers at Madison Square Garden on Tuesday. In the Western Conference, the Nashville Predators will look to take a 3-1 series lead against the St. Louis Blues in their second round match at Bridgestone Arena in Nashville.
Here's an early look at each game:

The Senators rallied for a 6-5 win in Game 2 when Jean-Gabriel Pageau scored his fourth goal of the game in double-overtime Saturday. Pageau
has become a bit of a celebrity
since his four-goal outburst helped give Ottawa a 2-0 series lead. There's a chance left wing Clarke MacArthur (upper body)
will be in the lineup for Game 3
, as reported by staff writer Mike G. Morreale. The Rangers are considering
a few lineup adjustments
as well, according to senior writer Dan Rosen. Rosen also identified
five players for the Rangers who need to be better
than they were in Game 2.

The Predators took a 2-1 series lead when forward Cody McLeod and defensemen Ryan Ellis and Roman Josi each scored and goalie Pekka Rinne made 22 saves in a 3-1 win in Game 3 on Sunday. Ellis has eight points (three goals, five assists) during a six-game point streak, a playoff record for a Predators defenseman. One big key for the Predators in the win
was being able to contain
Blues right wing Vladimir Tarasenko, as told by LNH.com senior managing editor Arpon Basu. The Blues, meanwhile, are
hoping for a strong response
to even the series in Game 4, according correspondent Louie Korac. It certainly would be worth your time to read about how the
Predators have molded Nashville into a hockey town
, as told by director of editorial Shawn P. Roarke.

One game, but it was a good one

There was one game on the schedule Monday, but Game 3 of the Eastern Conference Second Round series between the Pittsburgh Penguins and Washington Capitals had enough twists and turns for a full schedule of games.
Here's a look at what happened Monday:

The Capitals won on a goal by defenseman Kevin Shattenkirk 3:13 into overtime to cut the Penguins' lead in the best-of-7 series to 2-1. Penguins center Sidney Crosby left the game 5:24 into the first period after a cross-check by Capitals defenseman Matt Niskanen and didn't return. The Penguins scored twice in the final 1:53 of regulation to send the game into overtime. Game 4 is Wednesday.
The game-winning goal served as a bit of
redemption for Shattenkirk
.
As for Crosby, the Penguins
did not say what his status would be
for the rest of the series.
Columnist Nick Cotsonika says Crosby's long-term health is
the Penguins' No. 1 priority
.

Here are some things we learned on Day 20 of the Stanley Cup Playoffs:

The Capitals are resilient
Coach Barry Trotz keeps saying this Washington Capitals team is different from those that haven't responded well to playoff pressure in the past. They demonstrated some of that characteristic Monday. After letting a two-goal lead slip away in the final 1:53 of the third period, they were on the precipice of falling into a 3-0 hole in the best-of-7 series. But they regrouped during the intermission and won on defenseman Kevin Shattenkirk's power-play goal 3:13 into overtime.

The Penguins have guts
The Pittsburgh Penguins lost center Sidney Crosby to injury 5:24 into the first period. They failed to score for most of the game. And then, with their goalie pulled in the final minutes, they scored twice in 48 seconds and forced overtime. Evgeni Malkin blasted a one-timer, then set up Justin Schultz for a point shot. It has to give them hope they can survive if Crosby is out for any length of time, and it has to put fear in the Capitals that Pittsburgh will be tough to beat even without Crosby.
