Dina Asher-Smith returned as Team GB’s women set a new British record to reach the 4x100m final at the Tokyo 2020 Olympics.
Asher-Smith, who last week was in tears after having to pull out of the 200m with a hamstring injury, recovered to produce an assured run in the third leg.
In the men’s sprint relay, GB also qualified for tomorrow’s final but the story was another poor baton handover from the US team.
It has troubled the Americans in the past, notably at the last Games in Tokyo when they were judged to have passed over the baton outside the exchange zone.
Elsewhere for Team GB, canoeist Liam Heath was unable to defend his K1 200m single title.
He managed to claim bronze on a photo finish, just edging out the Hungarian Kolos Csizmadia for third place.
In the boxing ring, it was another successful morning for GB as Galal Yafai made the flyweight final.
Yafai produced a relentless display to beat Kazakhstan’s Saken Bibossinov and guarantee himself a medal.
Looking ahead, it is a big day in the track cycling. Jason Kenny and Jack Carlin will aim to reach the quarter-finals of the men’s sprint. Kenny has said that Carlin is GB’s best bet for a medal.
Matthew Walls, world bronze medallist last year, is competing in the track cycling omnium.
