Olympic hammer finalist Sophie Hitchon was in record-breaking form in California over the weekend.
Sophie, not 21 until July, broke stadium records at two meets as she produced a consistent series of throws.
On Friday, the British record holder went out to 69.67 in Berkeley at the Brutus Hamilton Open and Distance Carnival - a record at the Edwards Stadium.
And the following day, at the Payton Jordan Cardinal Invitational in Stanford, she produced a winning throw of 70.53m, beating Sarah Holt (67.70m) into second.
Sophie’s throw was again a stadium record at the Cobb Track and Angell Field.
She said on twitter: “another 69m at Berkeley, not quite there, but got the stadium record. Another comp at Stanford, had 2 over 70 and finished with 70.53.”
The former Ivy Bank pupil started her 2013 campaign in March with 70.34m at the British Athletics Winter Throws Trials in Loughborough, before, in her first international appearance of the year, claiming a top 10 finish in Castellon, Spain, at the European Cup Winter Throwing, with a best throw of 66.69m.
Sophie - whose British record mark of 71.98m was set in qualifying for the Olympic final in London last August - is preparing for the European Under 23 Championships in Finland in July, and the Worlds in Moscow in August.
