Club thrower Jo Butterfield took gold with a world record of 22.81m in the F51 final – as ParalympicsGB enjoyed their most successful day at Rio 2016.
A total of 21 medals were won across five different sports, more than the best single day at London 2012 (18) and Beijing 2008 (19).
The Scots athlete opened her account with a 22.60m throw to put herself into the lead before her world record of 22.81m saw her claim victory and the eighth gold of Day Four. Teammate Kylie Grimes finished fourth with a best of 18.75m.
Butterfield said: “The last three throws were a little bit emotional, It’s just unbelievable, it’s what I’ve worked for and it feels so good to have done it.
“Five years ago my life changed completely in a moment and sport has given me a massive boost and a reason to carry on.”
Butterfield, from Glasgow, who previously played wheelchair rugby, said: “It is everything I have been working for with my coaches Phil and Shona, so to actually come and nail it is brilliant.
“It has been a tough few days and I must thank my medical team who got me here; it’s great to be able to do it for them.
“This is the result of a lot of hard work, but I love what I do. You need a lot of enthusiasm when it is raining in Scotland, to go out and put the time and effort in.”
It was a disappointing day for wheelchair racer Sammi Kinghorn, who was disqualified in the 400m T53 final, her second final of her debut Paralympics, for a false start.
