Following are notes and quotes from Saturday's coverage of the 2016 Rio Olympics on the networks of NBCUniversal:

TRIATHLON - NBC

Play-by-play commentator Al Trautwig on women's triathlon gold medal winner Gwen Jorgensen of the U.S.: "She did just enough in the swim to be part of the lead pack. She started out the cycling portion in the back of the pack, and then, accelerated to the middle, and then the front. Every time (Nicola) Spirig looked like she had something on her mind, Jorgensen responded. She put herself in this position. This was impressive. Tactically, from a competitive standpoint, and the gamesmanship that went on between those two." Note: Nicola Spirig of Switzerland won silver in the race

TRACK AND FIELD - NBC

Analyst Ato Boldon on Team USA winning the women's 4x400m relay for a record sixth consecutive time: "No other country has won more than two in a row - and now the United States has come and won their sixth in a row."

Boldon: "Last year, Williams-Mills came off the turn and ran by the United States to give Jamaica the world title. Allyson (Felix) had this properly measured, and it was no contest in the final 100m."

Play-by-play announcer Tom Hammond on Centrowitz: "He's got it! The first American to win the 1500m at the Olympic Games since 1908!"

Analyst Craig Masback on Centrowitz: "We've been following the rise of Matthew Centrowitz since he first medaled in 2011 at the World Championships. As I mentioned, a disappointment in 2012 when he missed the podium by four one-hundredths of a second. He calls himself a strength runner, but he won that race with speed."

Analyst Tim Hutchings on Great Britain's Farah: "With all due respect, they didn't throw much at him. ... For Mo Farah, it was 'Thank you very much, I'll take that off the plate.' "

Masback on American Paul Chelimo winning the silver medal in the 5000m and the U.S. distance running: "Very significant, a silver medal for Paul Chelimo - no medals for the U.S. in this event since 1964. ... This is the sixth medal for the U.S. in middle- and long-distance running, the most since 1912."

Chelimo to reporter Lewis Johnson, learning of his initial disqualification during his post-race interview on NBC (Chelimo was later reinstated and awarded the silver medal): "I was trying to go to the outside to get a position, because they were blocking me in, they were pushing me to the rail. That's what I was trying to save myself from - all of the pushing, so I was trying to go the outside and stay to the outside. They wouldn't allow me to go where I was, because he was blocking me. ... I was trying to stay behind Mo Farah, but they were blocking me. I was trying to defend myself and go to the outside. ...

"I can't believe it. I was running a fair race. I wasn't trying to impede someone. I was trying to go to the outside, because they kept blocking me the whole time, the whole race. ... I want to appeal that because my intention was not to block anyone."

DIVING - NBC

Analyst Cynthia Potter on Boudia's last dive, clinching the bronze medal:"He said he hated this dive. But he also said he wanted pressure on it to give him the adrenaline he needs to complete these somersaults. He's had trouble completing the four-and-a-half somersaults. He wanted pressure? He got it. ... This is better than he's been doing. I think it was a good move to put this last."

Potter on Boudia's penultimate dive in the men's platform final: "What a dive. This is the dive that won him the gold medal in London, and it is going to score big - maybe bigger than what he did in London for the last round. This is the best one he's done."

Play-by-play announcer Ted Robinson on China's Chen Aisen, who won gold in the men's platform final: "Two gold medals, and a crushing final dive. Apprentice no more."

Potter on China's Qui Bo: "Nobody that had been around him the last four years would ever think that he would not be on the podium. He just had the pressure get to him."

Potter on Great Britain's Tom Daley, who won silver in London and led the prelims, not making the men's platform final: "His dreams have just been shattered, because that dive is very deficient. Jane (his coach) knows it; Lance (his fiancée) knows it; his mother knows it."

Robinson: "This will be, I think, the biggest single headline out of these Olympic games in Great Britain. Tom Daley, astoundingly, will not make the Olympic final. ... For the last two weeks we've been watching diving practices, we never would have thought this."

Potter: "No. Every practice I watched was so exciting, because Tom was diving so spectacularly."

SOCCER - NBCSN

Play-by-play announcer Arlo White on the gold medal-clinching goal by Neymar, as Brazil defeated Germany in penalty kicks in men's soccer: "At the Maracana, in Rio de Janeiro, Neymar to win the gold medal for Brazil - and scores! Brazil strike Olympic gold for the first time in their history! They've completed the set of international titles at last, and it's Neymar who is the hero!"

SUNDAY

"Inch for inch, pound for pound, the most stunning athlete I've ever seen," Mary Carillo on Simone Biles

"I can't wait to come back again. There's a great vibe to the country as a whole - and to this city," Mike Tirico on Brazil and Rio de Janeiro

Following are highlights of Sunday's coverage of the Games of the XXXI Olympiad from Rio de Janeiro, Brazil.

NBC concluded its coverage of the 2016 Rio Games with the closing ceremony, hosted by Mike Tirico, Mary Carillo and Ryan Seacrest, from Maracana Stadium in Rio. Coverage across the networks of NBCUniversal was highlighted by Kevin Durant leading the U.S. men's basketball team to its third consecutive gold medal with a 96-66 rout of Serbia; American boxer Claressa Shields winning her second consecutive gold medal; the U.S. men's volleyball team winning the bronze medal against Russia; and American runner Galen Rupp earning the bronze medal in the men's marathon.

Following are excerpts from Sunday's coverage of the 2016 Rio Games across the networks of NBCUniversal:

CLOSING CEREMONY - NBC

Tirico: "Not be a Pollyanna about it - there are problems, there are issues, and they were present here at the Games. Whether it was game, or it was traffic, the conversation leading up about Zika - many of them were around, and are going to be there when all pack up and go home, and the Games are a memory. But there is so much that is so good about this place. I had the chance to experience it in 2014 when soccer's World Cup was here. I couldn't wait to come back, and I can't wait to come back again. There's a great vibe to the country as a whole - and to this city."

Carillo on the Rio Games: "Brazil has had a pretty great Games. Nineteen total medals, which is a record for them, including seven gold medals, which is another record. The first of which was won by a 24-year-old judoka named Rafaela Silva, who comes from a famous favela, known as the 'City of God.' That's when I started crying. This is my 13th Olympics - I've never cried so much watching the athletes cry out of joy and out of sorrow. I'm glad we're having a big party tonight."

Carillo on what she will take away from the Games: "The good stuff, the joyous stuff, the hard stuff, the depressing stuff. ... When you're in Brazil, I love it, but I love it with clear eyes, the way you're supposed to love anything and anyone. The hope is that now that people have discovered Brazil and have come to understand it and its challenges, it will only get better."

Carillo on Japanese Prime Minister Shinzo Abe and the upcoming 2020 Tokyo Games: "When he was awarded the 2020 Games in Tokyo, he said, 'When I heard the word Tokyo, I was so touched and overwhelmed, the joy was even greater than when I won my own election.'"

Seacrest on the significance of Brazil's men's soccer team winning gold: "I was in a taxi earlier today, and the driver said to me, 'You know what? All is good, because we won gold in football.' "

Carillo on American Simone Biles, who won five medals in Rio: "Inch for inch, pound for pound, the most stunning athlete I've ever seen."

BASKETBALL - NBC & NBCSN

Analyst Doug Collins on the U.S. men's basketball team's dominant performance against Serbia in the gold medal game: "You know that beautiful song by Vanessa Williams, 'Save The Best For Last?' Well that's what the United States have done. They've saved the best for last. This is their best performance (of the Rio Games) at both ends of the floor."

Collins on Durant, who scored 24 points in the first half and 30 in the game : "A lot of speculation coming into this game. Could they beat Serbia? Serbia played them to a three-point game, had a chance to tie that game. ... Kevin Durant took only four shots in that game. In 2010 (FIBA World Cup), the 2012 gold medal game, and the Olympics here ... he's come up money. He's a dynamic scorer - he was built and born to score."

Collins on U.S. men's basketball head coach Mike Krzyzewski: "This is a bittersweet moment for Coach K. He's put 11 years into USA Basketball. He's done a magnificent job, winning his third gold medal. He won two gold medals in the FIBA World Cup and went undefeated in Olympic basketball. But more importantly, what he and Jerry Colangelo have done is uplift USA Basketball once again. After Athens, they've infused this feeling among NBA players to be a part of this family and this culture."

Analyst Fran Fraschilla on the impact of the bronze medal for Spain in their 89-88 win over Australia in men's basketball: "In international competition the teamwork, the effort, the sacrifice ... a bronze medal is huge."

INDOOR VOLLEYBALL - NBC & NBCSN

Analyst Kevin Barnett on the men's indoor volleyball gold medal-winning Brazilian team: "What a payoff for a country stretching to host the Olympic Games. To win in their top two sports - soccer and now indoor volleyball. Gold on the beach, as well."

Barnett on Brazil defeating Italy in straight sets to win gold: "An incredible moment for Brazilian volleyball. They worked so hard to get here, so many times with failure in the finals. What a job by this group. ... Italy played their best volleyball when it mattered, but they just ran into a Brazilian team that played better."

Barnett on the resiliency of the U.S. men's volleyball team, earning a bronze medal in a victory over Russia: "Sweet vindication for the U.S. side. How do you erase the bitterness of 48 hours ago? You come out with a victory and do it with exciting fashion. The U.S. giving Russia a little taste of its own medicine from four years ago." Note: USA came back to defeat Russia in five sets after dropping the first two sets to capture the bronze medal

Barnett on the future of U.S. men's volleyball: "(Head Coach) John (Speraw) said of his young team, 'I am already proud of this young group. What they have accomplished from the start of this tournament, to where they went, I'm proud of who they are and how they have handled it.' ... No matter what the result of today is, his players will take on a new threshold for what it takes to win."

MARATHON - NBC

Analyst Hutchings on men's marathon gold medal winter Eliud Kipchoge of Kenya: "He was an outstanding favorite. This man has such an astonishing career. When he was 18 back in 2003, he won the world 5,000m title. Here he is all these years later moved on to the roads and made the most spectacular conversion from track to roads in the history of marathon running. Beautiful looking runner - bounces nicely, wonderful dimensions, powerful, amazing speed."

Analyst Masback on bronze medal-winner Rupp of Team USA: "No American had won a medal in the marathon since 1908, before Frank Shorter won in 1972. So, the significance of Galen Rupp being among the leading three in this race is huge."

Masback on the struggle of Team USA's 41-year-old Meb Keflezighi, who finished 33rd: "When we're watching these lead runners who look so easy as they go through the race, you forget about how hard the race is and how it takes its toll on individuals. For you to succeed in a marathon race, everything has to be right in the day. You can only fight through so much and remain competitive at a race at this level."

BOXING - NBCSN

Analyst B.J. Flores on Team USA's Shields prior to her gold medal-winning match: "She's been ultra-impressive. She's done an excellent job of really using her experience so far throughout this tournament and letting her opponents know that they don't belong in the same ring with her, so she's used that poise, that experience to really put them at a disadvantage. She comes in with a lot of confidence and that's very valuable in a matchup like this."

Flores on Shields' success: "She had her way with her opponent today, was able to just stay on the outside, land the big shots, counter whenever she wanted and really use her experience and her poise to get the job done and win every single round."

RHYTHMIC GYMNASTICS - NBC daytime

Russia won its fifth consecutive gold medal in the group competition. Spain took the silver medal.
