England's Sophie Thornhill and her pilot Helen Scott won the first Para-sport gold of Glasgow 2014 with victory in the tandem sprint event for blind and visually-impaired athletes.
The pair, dominant throughout, beat Scotland's Aileen McGlynn and Louise Haston 2-0 in the best-of-three final.
The silver for McGlynn and Haston is the hosts' first medal of the Games.
"We went out to win and race the best we could and that got us the gold," Thornhill, 18, told BBC Sport.
The Cheshire teenager came to Glasgow having won two world titles with Wales' Rachel James in April.

Thornhill and Scott had finished fastest in qualifying at the Sir Chris Hoy Velodrome before beating Australians Felicity Johnson, the Paralympic champion, and her new pilot Holly Takos 2-0 in the semi-finals.
And the English pair again showed their strength in the final, winning a cagey first heat after swooping into the lead with just over a lap to go.
Scott, who celebrates her 24th birthday on Friday, again guided her tandem into a strong position in the second heat and they could not be caught.
Thornhill and Scott will go for a Glasgow 2014 double in Sunday's kilo.
"We had such a great time out there," said Scott.
"We don't know whether our events will be in the Commonwealth Games next time so we just want to relish it."
