Great Britain's Paralympic gold medallist Jonathan Fox has comfortably secured a place in the men's S7 100m freestyle final after finishing second in heat one.
Fox, who won gold in the S7 100m backstroke, was neck and neck with the USA's Lantz Lamback on the final leg.
The Brit, who could only set the fifth fastest time in the qualifiers, started off well but it was his American opponent who edged the fastest time of 1:02.33, while Fox secured his place in the final in 1:02.47.
Fox's compatriot Josef Craig also booked a place in tonight's final after coming second in his heat with a time of 1:04.00.
