1) Simone Biles Goes for Fourth Gold Medal
On the final day of gymnastics, Team USA superstar gymnast Simone Biles soared to her fourth Olympic gold medal on Tuesday, winning the floor exercise. The 4-foot-8 powerhouse earned a 15.966.
Aly Raisman won a silver medal after a routine that included a perfect double layout. She scored 15.500, which was enough to beat Britain's Amy Tinkler, who won a bronze medal with a 14.933 score.
Biles will return home with four golds and a bronze. Raisman now has six Olympic medals. She won gold on the floor in London.
Danell Leyva won two silver medals, on high bar and parallel bars. Leyva went last on the bar and his score pushed Team USA's Sam Mikulak out of a bronze medal.

2) Christian Taylor Defends Triple Jump Gold Medal
Team USA's Christian Taylor successfully defended his Olympic triple jump gold medal Tuesday.
He set a season-leading mark of 17.86 on his first attempt and posted the three best jumps of the competition.
Taylor claimed a gold medal at the London Olympics and won the 2015 World Championships. He switched his lead leg in 2013 after he developed pain in his left knee. He compared the adjustment to starting to shoot a basketball layup with the opposite hand.
3 ) Maryland Boxer Fights in Quarterfinals
Prince George's County's own Gary Russell lost his fight with Fazliddin Gaibnazarov of Uzbekistan 2-1.
Russell, a 20-year-old who weighs in at 141 pounds, was his family's second chance at a gold medal. As News4's Tracee Wilkins reported, Russell's older brother was devastated when he was unable to compete in the Beijing Olympics.
