Here, we wrap up the action from across Rio and looks ahead to today:

* Andy Murray beat Juan Monaco of Argentina in the men’s singles, the defending champion winning 6-2 6-1 in his second-round encounter, but Johanna Konta had to come through a three-hour battle against Svetlana Kuznetsova before prevailing 3-6 7-5 7-5.
* Britain’s women’s gymnasts finished fifth in the team competition as the United States claimed a dominant victory.
* City of Leeds pair Tonia Couch and Lois Toulson finished fifth in the women’s synchronised 10 metres platform final, where the water in the pool attracted attention for being green.
