Three big things about Team USA

1. Men's basketball handles Serbia in Olympic opener

Kevin Durant did not miss a shot in the first half as Team USA pulled away from Serbia 110-84 in its Olympic opening match Sunday. Durant's 23 points led the team as they earned a crucial two standings points. Team USA next faces South Sudan on Wednesday, who nearly won against the Americans in a warm up game on July 21.

2. Swimming delivers top action yet again

Drama in the pool was of no shortage Sunday. France's Leon Marchand gave the home fans something to cheer about early, earning gold in the men's 400 Individual Medley. American Torri Huske edged out teammate Gretchen Walsh for gold in the women's 100 Butterfly while Great Britain's Adam Peaty and U.S. co-captain Nic Fink tied for silver in the men's 100 Breaststroke. Fink's other co-captain Ryan Murphy barely qualified for the men's 100 backstroke final.

3. Women's soccer defeats Germany to qualify for quarterfinals

Team USA put away a strong Germany side 4-1 in its second group stage match Sunday. Sophia Smith scored twice and Mallory Swanson tallied the go-ahead goal in the first half alone. Lynn Williams put the iced the match late in the second half. The Americans will play Australia on Wednesday needing only a draw to win their group.

You won't believe this

Tennis legends Rafael Nadal and Novak Djokovic are set to face off in the Olympic tennis second round in what is usually a matchup reserved for a Grand Slam final. With Nadal's professional future in question after the Paris Games, this could be the final time the two greats meet in a competitive setting.

Also, Team Japan women's soccer pulled off an incredible upset Sunday morning, scoring twice late in second half stoppage time to defeat powerhouse Brazil 2-1.
