Coming off its incredible medal comeback in a number of events, the U.S. was looking for another big medal day as the Tokyo Games continued Sunday night and into Monday morning.
It was an eventful day that saw medals awarded in men's gymnastics, fencing, cycling, diving, shooting, skateboarding, swimming, table tennis, triathlon and more.
Local triathlete Kevin McDowell stepped into the global spotlight and made history in his first Olympics ever.

Here are five things to watch from Sunday night and Monday morning in Tokyo.
1. Team USA Finishes Fifth in Men's Gymnastics Team Final
The U.S. men's gymnastics team missed out on a medal in the team event for the third straight Olympics after finishing in fifth place at Monday's final.
Team USA, made up of Brody Malone, Sam Mikulak, Yul Moldauer and Shane Wiskus, had the fourth-best score in team qualifying but finished just behind fourth-place finishers Great Britain by a little over a point.
The Russian Olympic Committee won gold, edging host nation and defending Olympic champions Japan by just .103 points. Japan claimed silver and China won bronze.
2. Geneva Native Kevin McDowell Places 6th in Men's Triathlon - A Record for an American Man
Geneva native Kevin McDowell finished sixth in the men's triathlon, marking the best finish by an American since the event was added to the Olympics in 2000.
McDowell finished 50 seconds behind Kristian Blummenfelt of Norway, who had a time of 1:45:04. Alex Yee of Great Britain and Hayden Wilde of New Zealand claimed the silver and bronze, respectively.
The 29-year-old, who was one of three American men to qualify for the race, is a seven-time World Triathlon Cup medalist and the 2017 USA Triathlon Elite national champion, but his biggest victory in his life came after he was diagnosed with Hodgkin’s Lymphoma in 2011.
3. Momiji Nishiya Wins Women's Skateboarding Street, USA's Alexis Sablone Finishes Fourth
At just 13 years old, Japan's Momiji Nishiya skated into history Sunday night by winning the first-ever women’s Olympic street skateboarding event in Tokyo. Nishiya helped the host nation sweep both the street competitions after Yuto Horigome won gold in the men's event the previous day. Nishiya made more history in addition to winning the events Olympic debut; she also became one of the youngest Olympic gold medalists ever.
American Alexis Sablone finished fourth after scoring 13.57 points, just missing the podium. Sablone, a seven-time X Games medalist (winning in 2015, 2012 and 2010), grew up in Connecticut and started skateboarding at the age of 10.
4. Swimming Medals Won, Softball Continues Winning Streak
Four more swimming medals were awarded Sunday night during finals for the women’s 100m butterfly, men’s 100m breaststroke, women’s 400m freestyle and men’s 4x100m freestyle relay.
In men's swimming, the U.S. won the 4x100m freestyle relay in a time of 3:08.97. The Americans had a .20-second lead going into the final leg, and Zach Apple pulled away from the pack to secure the gold.
Meanwhile, Katie Ledecky had to settle for silver in her first final of the Tokyo Olympics, as Ariarne Titmus of Australia took the gold in 3:56.69. Ledecky was about six-tenths of a second behind at 3:57.36 and held the lead for most of the race until Titmus overtook her in the last 100m.
Li Bingjie won the bronze, more than two seconds behind Ledecky and Titmus.
Meanwhile, in its last match of the preliminary round, the U.S. softball team earned a walk-off win when Kelsey Stewart hit a solo home run. Japan nabbed the early 1-0 lead in the first inning before the Americans equalized in the sixth.
The U.S. had already advanced to the gold medal round before the match began and has now finished the preliminary round a perfect 5-0.
5. Chicago Fencer, Notre Dame Alums Take Stab at Fencing Medals
Chicago-area athletes competed in the women's individual sabre events Monday, but didn't make it to the medal rounds.
Mariel Zagunis, the most decorated fencer in U.S. history, fell short in the quarterfinals of the event when she lost to ROC's Sofya Velikaya. The University of Notre Dame alum has competed in four prior Olympics and collected two gold medals and two bronze medals. She won her first gold medal in 2004 at the age of 19, becoming the first US fencer to capture gold in a century.
Olympic newcomer and Chicago fencer Eliza Stone also competed in the event but dropped her first match.
On the men's side, fellow Notre Dame alums Nick Itkin and Gerek Meinhardt also did not make it to the medal rounds in the men's foil event.
