A stunning night at the Olympics Aquatics Stadium saw several of swimming's biggest names deliver performances befitting the grand stage.
Katie Ledecky, Adam Peaty and Sarah Sjostrom all lowered their own world records en route to spectacular victories on day two of the swimming competition at Rio 2016, while Michael Phelps earned his 19th gold medal.
There was an air of inevitablity surrounding Sunday's three individual finals and each of the favourites emphatically lived up to their billing.
Sjostrom was the first to shine, a time of 55.48 seconds in the 100m butterfly enough for her to triumph by a wide margin and become the first Swedish woman to claim an Olympic gold medal in the pool.
Great Britain's Peaty had already improved his 100m breaststroke world record to 57.55 in Saturday's heats, but shaved a further 0.42secs off that mark to claim a similarly dominant victory in his final, with Cameron van der Burgh a distant second.
Ledecky, the most dominant figure in women's swimming, then lowered her 400 freestyle record to a staggering time of three minutes and 56.46 secs, the American teenager beating Britain's Jazz Carlin by almost five seconds to take her maiden Olympic gold.
And the action was fittingly rounded off with yet more success for Phelps, who starred as the United States prevailed in the men's 4x100m freestyle relay. Phelps now boasts 23 Olympic medals in all.
RACE OF THE DAY
There was much to admire throughout Sunday's evening session, but Ledecky's victory was arguably the most staggering of all - the outcome certain almost from the outset. Expect repeat performances from the 19-year-old over the coming days.
Sjostrom set the tone for another high-quality evening session and from that moment on the records kept on tumbling, to the delight of the crowd at the Olympic Aquatics Stadium.
QUOTES OF THE DAY
"I took it easy today. I swam in the morning then later I played Yahtzee with my room mates," - Sjostrom apparently had no problems remaining calm and collected ahead of the biggest race of her career.
"I've no idea what my nan [grandmother] is tweeting. I've been on Twitter for a few days. She's great. My nan has always loved swimming," - Peaty comments on the interest shown in his grandmother's recent Twitter activity.
Four more golds are up for grabs on Monday, starting with the men's 200m freestyle final, for which Sun Yang posted the fastest qualifying time. Reigning champion Yannick Agnel bowed out in the heats and later announced Rio would be his last Olympics.
