There has been no shortage of must-see action on Day 5 of the Tokyo Olympics. Katie Ledecky won the first-ever gold medal in the women's 1500m freestyle, one of four medals Team USA took in the pool Tuesday night.
Shortly after, Kevin Durant and the U.S. men's basketball team rebounded after their disastrous opening loss -- their first Olympic loss since 2004 -- to beat Iran in a blowout. And Team USA and New York's Stefanie Dolson just beat ROC in the first-ever Olympics women's basketball 3x3 final.
Without further ado, here are our 4 to Watch on Day 5:

1. Katie Ledecky, Team USA Have Another Impressive Night at the Pool
Coming off a disappointing fifth place finish in the 200m freestyle earlier in the night, Katie Ledecky took gold in the women's 1500m freestyle — the first time the event has been held for women in the Olympics. Teammate Erica Sullivan finished with the silver medal. Ledecky set an Olympic record in the inaugural 1500m heats.
Team USA got two other medals on the night, both coming in the the women’s 200m butterfly. Westchester County's Kate Douglass took bronze, while University of Virginia teammate Alex Walsh finished second.
Tokyo marks Douglass' first Olympics. The Pelham homer graduated from Pelham Memorial High School in 2018.
Despite having entries in the men’s 200m butterfly and men’s 4x200m freestyle relay, Team USA came up empty in both contests. The lineup of Kieran Smith, Drew Kibler, Zach Apple and Townley Haas was in a tight race for the bronze medal in the relay, an event the U.S. had won in four straight Olympics, but came up short and finished in fourth place. In the 200m butterfly, Gunnar Bentz finished seventh.
The night’s action also included semifinal races in the men’s 100m freestyle, women’s 200m butterfly and men’s 200m breaststroke — all of which saw Americans advance to the finals, presenting more opportunities for Team USA to take home hardware.
2. US Women's 3×3 Basketball Team Beats ROC to Win Sport's First Gold Medal
The four members of the U.S. women's 3x3 basketball team won gold and made history.
For future trivia questions asking who won the first Olympic gold medal in women's 3x3 basketball, the answer will be: New York's own Stefanie Dolson, Allisha Gray, Kelsey Plum and Jackie Young of the United States of America.
That quartet of WNBA players led the U.S. to an 18-15 victory over the Russian Olympic Committee in the first ever women's 3x3 basketball gold medal game on Wednesday.
The outcome was never in doubt as the Americans jumped out to an 8-3 lead behind five early points by Plum.
After France cut the United States' lead to three, Gray drove baseline and converted a layup for a 15-11 advantage with 2:12 left.
Yulia Kozik hit a 2-pointer to pull ROC within 17-14 with 44 seconds remaining, but Dolson answered with a putback to push the lead back to four and seal the victory and gold medal.
Dolson finished with seven points and nine rebounds. Plum finished with five points, Gray added four points and five rebounds, and Young had two points and three rebounds.

3. US Men's Basketball Gets Back on Track After 1st Olympic Loss Since 2004
After getting stunned by France in the fourth quarter of their Group B opener on Sunday, which gave the Americans their first Olympic loss since 2004, Team USA rebounded against Iran to win handily, 120-66.
Damien Lillard led the way in scoring for Team USA with 21 points. Devin Booker added 16 points, and Jason Tatum scored 14 of his own. The game was never all that close, with the U.S. leading 28-12 after the first quarter
Beyond momentum, the game carries weight for Team USA in the standings since only the top two teams in each group advance to the quarterfinals. The men's team next plays at 8 a.m. Saturday against Czech Republic, which is 1-0 after also beating Iran in its first game.
4. US Women's Water Polo Falls to Hungary, 10-9
Team USA has looked like a team determined to win its third straight Olympic gold medal in women’s water polo.
The team took an 8-6 lead into the final quarter of play, but was outscored 4-1 in the final frame. The U.S. even held a 9-8 lead with just over two minutes left to play, but Hungary responded with a quick goal right after, then scored the eventual game winner with 45 seconds left. It was the Americans' first Olympic loss in 13 years.
The team's next game is against the Russian Olympic Committee at 2:30 a.m. Friday, with first place in the group up for grabs.
Team USA's first loss of the tournament comes after a historic, 21-goal victory over host nation Japan on Saturday. The margin of victory was the most ever in a women’s Olympic water polo game … until Spain broke the record against South Africa just a few hours later. The Americans followed that outing up with a 17-12 win over China.
