Finding space on the ice is expected to be an ongoing challenge for the Ottawa Senators and Carolina Hurricanes in their Eastern Conference quarterfinals series.

So, finding any small edge will be critical when they meet in Game 2 on Monday night at Raleigh, N.C.

“The first round always has all the energy in the world and that’s what you expect,” Hurricanes coach Rod Brind’Amour said.

Carolina won 2-0 in the first game Saturday behind Frederik Andersen’s 22-save performance.

Both teams had difficulty finding openings and more of that could be in the works.

“I don’t think this series it’s ever going to look like there’s a ton of space out there,” Senators coach Travis Green said. “It’s going to look very similar every night. I think at the end of every game, both teams are going to feel like there wasn’t space on the ice and I don’t see changing.”

So, it came down to what the goalies could do.

“The goalies had to really shine,” Brind’Amour said.

Ottawa’s Linus Ullmark made 27 saves Saturday, but he fell to 5-11 in career playoff games. He was sharp as well, though Andersen stole the spotlight when it wasn’t clear leading up to the series opener if he would be Brind’Amour’s choice.

He had to decide between Andersen and rookie Brandon Bussi. Andersen got the call.

“He was up to the challenge,” Brind’Amour said. “We have good options and both guys have played well. Clearly, experience, I think won out. … Freddy has a track record and we know what he’s capable of.”

Green said to win on the road in the playoffs the goalie has to play well (and he liked Ullmark’s outing) and a power-play goal or two would be a boost.

The teams combined to go 0-for-9 on power plays in Game 1, with the Hurricanes having five chances.

“They’re a quick team,” Green said. “They’re good in this building.”

Carolina’s relentless nature is something the Senators need to be ready for again.

“They’re deep,” Green said. “They’re good. … Carolina does a real good job of playing their game.”

Carolina’s Logan Stankoven supplied a goal and an assist in the series opener, extending a strong stretch. He had an eight-game points streak to end the regular season.

Three of Stankoven’s four multi-point postseason outings have come with the Hurricanes. His line has been rolling up strong numbers for the past few weeks.

“We have a lot of depth,” Stankoven said. “Since the break, our line has been clicking pretty good. We’ve been able to find each other and I think we’re all hungry to track pucks.”

Now the Hurricanes will look for upgrades on power plays.

“If we look at one area we’re not overly happy with is our power-play chances,” Stankoven said. “Every team as a series goes on makes adjustments.”

Carolina improved to 7-0 in its last seven postseason opening games. The Hurricanes put together some quality stretches in the offensive zone.

“They probably deserved to win analytically, and they did,” Green said.

The Hurricanes have won 12 of 18 all-time best-of-seven series when winning Game 1.

Mitch Keller pitched seven strong innings, allowing two runs to help the host Pittsburgh Pirates score a 6-3 win over the Tampa Bay Rays on Sunday afternoon.

Coming off a 13-inning loss on Saturday where Pittsburgh used six relievers, Keller (2-1) preserved some arms for the Pirates bullpen and helped his team take two of three games against the Rays, who entered the series having won six in a row.

Bryan Reynolds backed up the pitching with two hits and three RBI to lead Pittsburgh’s bats, while Spencer Horwitz and Nick Yorke each hit solo home runs.

Nick Gonzales had two hits and an RBI and Jake Mangum also had two hits. The Pirates did it with the long ball and small ball as they recorded three bunt singles in a game for the first time since 1998.

After picking up his first win in three years in his previous start, Rays starter Shane McClanahan (1-2) was unable to follow up that success, nor spare Tampa Bay’s own taxed bullpen a day after it used seven relievers. He allowed four runs on eight hits and struck out five over 4 1/3 innings on 90 pitches.

Keller picked up his second win in his fifth start of the season after not doing so last season until his 17th start. He struck out five and gave up five hits and did not issue a walk on 89 pitches.

The Rays took a 2-1 lead in the top of the fifth on a two-run single by Hunter Feduccia off Keller, which was one of Tampa Bay’s six hits overall. Jonny DeLuca followed a Richie Palacios double and then stole second to set up Feduccia’s go-ahead hit.

The Pirates answered immediately when Joey Bart doubled and Billy Cook followed with a bunt single and stole second. Two batters later, Gonzales singled to drive in Bart, and Reynolds followed with a two-run single to put Pittsburgh ahead 4-2.

Right-hander Wilber Dotel was called up from Triple-A Indianapolis and made his major-league debut in the ninth. He allowed a solo home run to Junior Caminero, but then struck out Jonathan Aranda and retired Yandy Diaz on a ground out, and Cedric Mullins on a fly ball to center. The Pirates optioned reliever Cam Sanders to Triple-A Indianapolis.
