Splitting medals is unusual, but it happened three times on Day 4.
In both other instances, there were no silver medals handed out as the competitions ended in ties for gold.
In the men's coxless pairs rowing event, Felipe Leal and Oscar Vasquez of Chile and Diego Lopez and Axel Haack of Argentina both crossed the finish line in 6:27.77.
The top of the podium again held twice the normal number of athletes after a tie for first in the men's pommel horse. Gymnasts JossimarCalvo Moreno of Colombia and MarvinKimble of the United States both scored 15.025 to split the gold.
