Nicola Adams became the second Great Britain boxer after Luke Campbell to guarantee at least a bronze medal after a comprehensive 16-7 win over Stoyka Petrova in her women's flyweight quarter-final at ExCeL.
The Leeds 29-year-old was simply too sharp for her Bulgarian opponent, wobbling Petrova with a short left and a right over the top in the first round, and again with a stabbing left in the second to lead 5-3 at the half-way stage.
The shorter Adams continued to do well with her countering lefts in the third, but Petrova, a former world quarter-finalist, was proving a difficult challenge as she pushed forward looking to land hooks with either hand.
Adams, however, was clearly more classy, pulling away to take a six-point lead into the final round and book at least bronze - and a titanic showdown with Indian sensation Mary Kom in the semi-finals on Wednesday.
