Competition began with the fencing event and the U.S. team got off to a strong start with four straight victories. But they faltered a bit in the second half of the fencing competition and finished in 8th position with 728 points.
The next event of the day was the swimming competition. Stettinius swam a time of 1:06.40 over the 100-meter freestyle course and Sacksen clocked in at 1:01.80, which placed them 9th for the swim.
The American duo moved up in the standing in the riding event by placing 2nd with 1160 points. This put them in 6th place in the overall standings, 1:06 behind the leaders, the Russian team of Ilia Frolov and Polina Struchtkova.
In the final discipline, the combined run/shoot event, both athletes shot well and Sacksen was able to pass China's Jiahao Han at the finish line of the run to clinch the bronze medal for the U.S.
"The result is simply awesome," said Stettinius. "This is my comeback event after I broke my collarbone and to cap it off with a bronze medal is a dream come true.
"I am very pleased, my hard training was the key to the final sprint which won us the bronze," added Sacksen.
The team from Germany won the gold medal in the mixed relay while Poland took the silver medal.
