• Men’s and mixed 4x400m quartets set new Australian benchmarks

An Australian team including sub 10-second man Lachlan Kennedy have equalled the national 4x100m record on a big day one for the green and gold contingent at the World Athletics Relays in Botswana.

Kennedy, Joshua Azzopardi, Christopher Ius and evergreen anchor leg runner Rohan Browning stopped the clock at 37.87sec – good enough for third spot in the heat and a berth in the final on Sunday (Monday AEST).
