Second gold
Chinese teenager Ye Shiwen won her second gold medal of London 2012 with victory in the 200m individual medley. The 16-year-old, who claimed gold and a world record in the 400m medley, clocked two minutes 7.57 seconds for a new Olympic best. Australia's Alicia Coutts won the silver medal in a time of 2:08.15, while Caitlin Leverenz, of the United States, got bronze in 2:08.95. Great Britain's Hannah Miley finished seventh in the final, clocking 2:11.29.
US comeback
The United States overcame a sluggish start to thrash Tunisia 110-63 in their second Group A match. Tunisia started strongly, scoring two early three-pointers and, with his team trailing 13-12, USA coach Michael Krzyzewski changed his entire team. They responded to surge into a 46-33 half-time lead and put on 39 points in the third quarter alone to end the chances of a major shock. The win was enough to move the tournament favourites top of Group A.
Silver win
Great Britain's eventers claimed Olympic silver behind Germany after a dramatic tussle with New Zealand. Holding a narrow lead over the Kiwis as the last riders prepared to go, Tina Cook sealed second place by collecting just one penalty. Cook and team-mate Mary King just missed out on a second medal in the individual equestrian event as German Michael Jung celebrated double gold.
Aust triumph
Great Britain's men's volleyball team were hammered 3-0 by Australia as they slipped to their second successive defeat of the Olympic tournament. Australia's aggressive serving proved too much for GB, as their rivals raced into an 8-1 first-set lead. They never recovered, losing the set 25-15, before better showings in the second (25-18) and third (25-20).
Brazil shock
Great Britain will play Canada in the quarter-finals of the women's Olympic football tournament after defeating Brazil 1-0 at Wembley. Steph Houghton struck from a tight angle in the second minute to score her third goal in as many games. Kelly Smith had a penalty saved after the break as GB went in search of a decisive second.
Tennis time
Jo-Wilfried Tsonga beat Milos Raonic in the longest tennis match in Olympic history to reach the third round. The Frenchman won 6-3 3-6 25-23 after three hours and 56 minutes, following a third and final set lasting 48 games - itself an Olympic record. Tsonga wasted three match points before winning the epic deciding set.
Players charged
The Badminton World Federation has charged eight Olympic doubles players with "not using one's best efforts to win a match". Four pairs of players — two from South Korea, one from China and one from Indonesia — could be disciplined. Constant errors, including players serving into the net, took place. All four pairs had already qualified for the last eight, and they have been accused of wanting to lose in an attempt to manipulate the draw.
