Blake Govers' campaign to follow in the footsteps of his Olympic medallist brother ended in heartbreak before it even started.

Sixteen-year-old Govers had been hoping to replicate the success of his older brother, Kookaburra and 2012 London Games bronze medallist Kieran, at the Australian Youth Olympic Festival (AYOF) hockey field.

Govers earned selection but on Wednesday was reduced to a spectator as the under-21 men's national team crushed USA 7-0 in their AYOF opener at Sydney Olympic Park.

A grade-one muscle tear during a training match on Tuesday afternoon ruled him out for the rest of the AYOF tournament.

"I used to come up to watch (Kieran) in the AYOF back in the day, so I was pretty keen and eager to get out there," Govers told AAP on Wednesday.

"It was pretty disappointing to hear I couldn't play."

Govers will spend the AYOF on the sidelines helping the team, but it's advice from his Olympic medallist brother which is helping him.

"You've got to relax and stop being so uptight about the game - that's the main advice (Kieran) gives me from when he went through (the AYOF).

"When he started relaxing, he started to play some good form."

Govers' focus is now on the Hockey Junior World Cup in December.

There was triumph for another hockey player with a famous surname on Wednesday.

Brooke Peris, niece of famous Hockeyroo Nova Peris, is one small step closer to her goal of winning an Olympic gold after the under-21 women's team secured their first win at the AYOF, beating Great Britain 3-0.

The twenty-year-old is one of four senior squad members of the Jillaroos, and she's out to make another Peris name famous.

"That would be the best, to win gold (at Rio de Janeiro) ... to try and play with the big girls," Peris told AAP on Wednesday.

Peris's journey to Rio is made a little easier having a role model in her 1996 Atlanta Games gold medallist aunt.

"I spoke to (Nova) yesterday and she (told me) to be creative with my own skills ... to do what you do best and do what you can for the team," Peris said.

"The rest I have to figure out for myself, because there are times when I'll have to learn by myself, and that's what she tells me."
