Where to begin is the question. Last night the U.S. Women’s gymnastics team of Simone Biles, Gabby Douglas, Ally Raisman, Laurie Hernandez, and Madison Kocian pulled off the repeat by winning the gold medal in the team competition in blow out fashion. In doing so they became only the 3rd U.S. Team to do so, and the first to repeat.

They also unveiled a new nickname, ” The Final Five”. It holds a two-fold significance in that it marks the final team that Martha Karolyi will coach, as this is her final Olympic Games, and going forward the teams will now consist of 4 members instead of 5. What a way to send off your coach.

At the pool, Michael Phelps and Katie Ladecky continued their dominance. Phelps avenged his 2012 loss in the 200m butterfly, his favorite event, by putting away the competition as he added to his unprecedented medal count, winning his 20th gold medal.

Later, he added to that total by anchoring the 4x200m freestyle relay team (Connor Dwyer, Townley Haas, Ryan Lochte, Michael Phelps) to gold. They simply obliterated the entire field from start to finish.

Katie Ledecky added to her legend and unbeaten string by winning gold in the women’s 200m freestyle.  This was gold medal number 2, with an anticipated 3 more opportunities to come. And to top it off, she has not lost a major international race since the 2012 Olympic Games in London.

Then there’s the disappointment of what happened to Serena Williams. The #1 women’s tennis player on the planet, and defending Olympic gold medalist was upset in straight sets by the Ukraine’s Elina Svitolina.

It was painful to watch as Serena struggled with her serve and overall mechanics all match. It has led some to speculate whether she was playing through injury. But Serena, not one to make excuses, released a statement saying that she is looking forward to her next outing and wants to put this disappointment behind her.
