The Olympic Games don't really begin until Michael Phelps has a gold medal around his neck.
Well, they are now underway.
Phelps gave his 4x100-meter relay team the lead on the second leg, and the Americans helped him secure a 19th gold medal. It was just one of many highlights in an entertaining night in the pool that saw two more world records fall, including Katie Ledecky crushing her own record.
Early in the day, the story in cycling, unfortunately, was a crash. Dutch cyclist Annemiek van Vleuten was on her way to a gold medal when she crashed and ended up in the hospital.
