Another historic medal came from the wrestling with Scotland's Viorel Etko claiming the bronze at the SECC Precinct. Etko's bronze in the men's 61Kg freestyle is the first wrestling medal in 20 years.
Today's medals takes Scotland's tally to 39, six more than its best result in Edinburgh 1986.
In the gymnastics at the Hydro, England's Max Whitlock topped the overall rankings to take gold, adding to his men's team win yesterday in which Scotland claimed silver.
