"I've had one or two asthma attacks when I've been playing but I just try to battle on," Stephenson said.
Being named in the tournament team at the North Island Regional under-15 championships in New Plymouth where her Bay team finished 10th in a 20-team B grade section was a significant achievement. Stephenson was the only B grade player (there were 219 B graders and 179 in a 16 team A grade competition at the champs) to be named alongside three from Auckland, four from Wellington, two from North Harbour and Hamilton and one from Manawatu in the 13-strong team.
Stephenson played every minute of the Bay's seven games at this tournament including two quarters at wing defence. She was also selected in tournament teams in Masterton and Hastings.
Palmerston North was the only tournament where she didn't gain tournament team selection. It wasn't because she was below par, quite the opposite in fact, officials at this event only selected a Year 8 tournament side.
A big fan of Silver Ferns captain and defender Casey Kopua and former Silver Ferns midcourter Temepara Bailey, Stephenson will aim for Hawke's Bay under-17 team selection next year.
Her Napier Girls' High School netball coach, national selector Charissa Barham, said Stephenson is "extremely coachable."
"Briana has tremendous speed from her athletics pursuits and she knows how to use that speed ... she is a lot more court smart now than at the start of the season."
While she is a dedicated trainer the modest Stephenson attributes a lot of her sporting success to the fact it's hereditary as her father and mother Trudi are both more than handy athletes.
Stephenson is hoping to embark on a sports science course at Otago University when she leaves school. It's likely to be around that time she has to make the choice between netball and athletics ... if she hasn't done so already.
