Botswana missed out on the men's 4x400 metres relay final at the World Athletics Championships on Saturday after dropping the baton in their semi-final heat while the United States ran the year's fastest time. Bahamas, Olympic champions on the same track five years ago, also failed to qualify for the final as did Jamaica. The U.S., aiming for a seventh world title in a row, ignored the trouble behind them as they stormed away to win the heat in 2:59.23 ahead of Trinidad and Tobago and Belgium. Jamaica were fourth while Bahamas, who also won bronze in Rio de Janeiro last year, trailed home in sixth.
