STORRS, Conn. -- The only way to tell Katie Lou Samuelson was a freshman playing in her first NCAA tournament game was with a scorecard.
Samuelson scored 22 points -- the most ever for a University of Connecticut player in her tourney debut -- as the top-seeded Huskies routed No. 16 Robert Morris, 101-49, in a Bridgeport Regional first-round game before a crowd of 4,784 at Gampel Pavilion on Saturday.
"I'm just feeling more confident and comfortable on the court and I know that I can do things to help out my team," Samuelson said. "I want to keep building on what I've done and not let up."
UConn's 70th straight win, which ties its own mark for the second-longest streak in NCAA history, sends it into a second-round matchup with No. 9 Duquesne here Monday night. The Dukes eliminated eighth-seeded Seton Hall 97-76 in Saturday's second first-round game.
Samuelson hit her first shot, a 3-pointer, and was into double figures in the opening 4:48. She had 17 at halftime and topped her previous best of 21 points with a pair of free throws 2:11 into the third quarter.
"You're always nervous for your first tournament game," UConn forward Morgan Tuck said. "Getting off to a good start is important and now I think she'll be good the rest of the way. Lou won't have those nerves. That's going to help us in the long run."
The foul shots also allowed the Huntington Beach, California, native to pass Jamelle Elliott and Kaleena-Mosqueda Lewis for the top performance for a UConn player in her NCAA debut. Mosqueda-Lewis had 21 points in a 2012 win over Prairie View A&M. Elliott had a double-double (21 points, 15 rebounds) in a 1993 first-round loss to Louisville. That was the last time the Huskies fell in the first round and lost a NCAA game at Gampel Pavilion.
"I think we all got off to a good start," Samuelson said. "I think our energy was really high. So it just made it easier for us to go on a run and we really made our defense transition to offense."
Six Huskies finished in double figures. All-American Breanna Stewart added 18 points, five rebounds, a career-high eight steals and her three blocks allowed her to break Rebecca Lobo's 21-year-old school record of 396. The North Syracuse, New York, native has 398 rejections.
All-American Moriah Jefferson, Kia Nurse and freshman reserve Napheesa Collier chipped in 14 points apiece with Nurse adding six assists and four steals while Collier grabbed a game high nine rebounds.
As expected, UConn (33-0) made quick work of the Northeast Conference Tournament champions.
"We just wanted to come out and show that no one plays harder than us," Stewart said. "We did that defensively, especially the steals, getting in the passing lanes. It made them a lot more hesitant."
Nurse opened the scoring with a trey and Megan Smith answered with a nice post move for the Colonials. The Huskies then netted 22 straight points.
A Samuelson 3 got it started, Tuck followed with two free throws and Samuelson had a pair of layups. Two more free throws by Tuck, Stewart's first basket, and a Samuelson three-point play kept it going. A Tuck hoop, two free throws by Nurse, and a Stewart basket made it 25-2.
After Anna Niki Stamolamprou scored for Robert Morris, the Huskies put up the next 16 points to end the first quarter with a 41-4 bulge. It was the most points for UConn in a quarter this season, as the Colonials finished 2 for 12 from the floor with 13 turnovers.
"We did a really good job of getting into the passing lanes and disrupting their flow on offense," Nurse said. "And our offense was just clicking. We were finding people at the right times and at the right spots. We looked up and saw we had 41 points and thought, 'It's not even the second quarter yet.' It was all good."
It was 64-15 at halftime. Robert Morris (20-13) wasn't quite sure what it hit.
"Obviously we scouted them but you really don't know what a 6-5 girl is like until you're up against her," Smith said. "The tempo was really fast. Their strength -- all of their players were just so strong. It felt like I was battling a post even though they were a guard. Defensively they're all up in your shorts and they never take a possession off. They're always in the passing lanes. They're on point, every time."
Saniya Chong's basket with 3:39 left put the Huskies into triple figures with 3:39 left.
Stamolamprou led Robert Morris with 11 points. The Colonials had 29 turnovers.
It was the final game for veteran Robert Morris coach Sal Buscaglia, who has announced his retirement. During the postgame handshake line, he received long hugs from UConn coach Geno Auriemma and associate head coach Chris Dailey, along with Jefferson and Stewart.
He then spoke to his team in the locker room.
"We were all very, very emotional," Smith said. "There were some tears shed. But it was happy tears. He was very proud of us. He was proud of how we handled the second half and how we finished the game. He said that he was proud that he got to experience all of this."
"I think it hit me as I was walking off the court," Buscaglia said. "As I walked off I thought, 'This is the last time.' I think it will probably hit me in October when practice starts."
Duquesne (28-5) received 25 points, 12 rebounds, and five assists from Deva'Nyar Workman in pounding Seton Hall. The Huskies and Dukes have met one previously, an 88-60 UConn win here in the final of the Connecticut Classic on Dec. 10, 1995.
