By day's end, Team USA held a commanding lead over the rest of the field with 26 medals overall. Here's aglanceat the 2016 Olympic medal count as it looked at the close of the fourth day of competition in Brazil.

Team USA day 4 Olympic medal count is golden

Although Michael Phelps' nearly back-to-back wins in the men's 200m butterfly (which, to the delight of #PhelpsFace fans, concluded with Chad le Clos in fourth place) and the 4x200m freestyle relay cemented Team USA's position atop the Olympic medal count standings, the Baltimore native wasn't the only member of the nation's delegation to bring home gold on day four.

In all, Aug. 9 saw four first place finishes for American athletes. In addition to the gold for Phelps and relay teammates Townley Haas, Ryan Lochte, and Conor Dwyer,Katie Ledecky out-touched Sarah Sjostrom of Sweden for gold in the women's 200m freestyle, and the #FinalFive ladies of the women's gymnastics team --Simone Biles, Aly Raisman, Gabby Douglas, Laurie Hernandez, and Madison Kocian-- cruised to gold over second-place Russia by more than eight points. The podium-topping performances gave Team USA the lead in the gold medal count with nine.

China second in Olympic medal count and gold medal count

With 17 total medals --including eightgold-- Team China ranked second in both the gold and overall Olympic medal counts on day four.

Japan, whose athletes have won the most bronze medals to date (10), ranked third with 14 medals, while Russia --the only other team to have reached a double-digit medal total to date-- was fourth with 12. With nine medals each, Australia and Italy shared fifth place, and four nations rounded out the top 10 with six medals apiece: Hungary (which is the home of Rio 2016 swimming super star Katinka Hosszu), South Korea, France, and Great Britain.

Team Canada is alone on the overall Olympic medal count standings with five podium placements. The remaining 36 nations represented on the leader board by the close of day four of Rio 2016 have won four or fewer medals at the Summer Olympic thus far.
