Once again banking on its dominate poolside performances, the United States widened its overall medal lead over China by two after Monday’s events at the 2016 Rio Games but remains knotted with the Chinese in gold.

As of publication time Tuesday morning, Team USA increased its medal tally to 19, claiming seven altogether Monday, including two gold after swimmer Ryan Murphy won men’s 100-meter backstroke and Lillia King took down the women’s 100-meter breaststroke.

The U.S. has reached five gold medals, but China continues to keep level at the diving board and pool. Yang Sun pulled away with the men’s 200-meter freestyle and divers Yue Lin and Aisen Chen won the men’s synchronized 10-meter platform for China’s fourth and fifth golds, respectively.

Sun also claimed a silver in the 400-meter freestyle, however, gold-medal winner and Australian Mack Horton called Sun a “drug cheat” after beating him by .16 of a second. Sun later cried at the post-race press conference and accused Horton of trying to get in his head, and the two will square off again in the 1,500-meter freestyle on Friday.

The Chinese, however, remain second to the U.S. with 13 total medals, while Australia stays in third place with seven total medals following shooter Catherine Skinner’s gold-medal performance in women’s trap. The Australians now own four golds, one more than Italy, which counts three golds out of its nine total medals.

Meanwhile, Japan sits in fifth place on the medal leaderboard with 10, including three gold, followed by Hungary in sixth with three golds and no others. Russia has managed to pull down 10 total medals (two gold, five silver, three bronze) despite more than two-thirds of its total delegation banned for alleged roles in a state-sponsored doping program.

South Korea is eighth with five medals, while Thailand and Great Britain each have four medals to round out the top 10 leaders. Altogether, 20 countries have secured at least one gold after nearly one full week of competitions, including host nation Brazil.

Martial artist Rafaela Silva won the women’s 57-kilogram judo competition for Brazil’s first gold, and Felipe Almeida Wu claimed silver in the men’s 10-meter air pistol.

Here’s an updated and live medal leaderboard below that will refresh and re-tally after each event.
