A daily double, as Michael Phelps became the winningest Olympic athlete by capturing his 10th and 11th career gold medals.

He began his day by setting a world record in the 200-meter butterfly with a time of 1:52.03, and later set a blistering pace of 1:43.31 to lead the U.S. freestyle relay team to a world record in the 800-meter. The Americans became the first team to break the seven-minute barrier with a time of 6:58.56, which shattered the old mark by more than four seconds.

He joked with reporters on his equipment malfunction in the first race. During the butterfly, his goggles became water-filled, and Phelps shrugged off the victory knowing that he could have done better. He is now halfway toward dethroning Mark Spitz and winning eight gold medals in one Olympiad.

Everyone wanted a glimpse at history, as the U.S. Basketball team cheered from their poolside seats. LeBron James posed for photos with Phelps’ mom prior to the competition.
