Jonnie Peacock's bid for the T43/44 100m title at the Paralympic Anniversary Games has fallen short after world record runs by Brazil's Alan Oliveira and the USA's Richard Browne.
Oliveira won the final in a new best time of 10.57, while Browne broke the T44 record with 10.75.
Peacock, though, still achieved a career best time of 10.84 to finish third at the Olympic Stadium as the three-day athletics event comes to an end.
