Rugby Sevens: All Blacks Sevens stay alive at Los Angeles with pool win over Samoa

Black Ferns Sevens star Tyla King has become the leading alltime women's scorer on the world series, helping her team through to the Los Angeles quarter-finals with a 40-0 pool victory over Brazil.

After overrunning South Africa in their tournament opener, the NZ women were just as ruthless against the South Americans, booking a spot in the final eight, with another pool game against Fiji still to come.

All eyes were on King, who equalled the previous mark - previously held by Canadian Ghislaine Landry - with a conversion of Michaela Blyde's second try just before halftime and broke it with a try of her own seconds later, after the siren.

As Tyla Nathan-Wong, the Tokyo Olympics gold medallist has also represented the Black Ferns XVs side, before switching to rugby league, where she helped the Kiwi Ferns upset the world champion Australia Jillaroos in last year's inaugural Pacific Championship final.

Days later, she was named World Rugby Women's Sevens Player of the Year. 

"It's pretty awesome, especially when most of those points have come from the right boot and not scoring tries," she reflected. "I don't think I've scored that many in my career."

Blyde had a hattrick of tries against Brazil, with King, Portia Woodman-Wickliffe and Tenika Willison also crossing the chalk, and King adding four conversions. 

Meanwhile, the All Blacks Sevens have failed to progress out of pool stages, with a 28-19 defeat to hosts United States, a week after losing the Vancouver final to Argentina.

The NZ men only needed a few seconds to open their account against the Americans, with a try to Scott Curry, but from the restart, speedster Perry Baker sprinted the length of the field to level the scores and quickly had a second, after gathering the kickoff.

Before halftime, Joe Schroeder extended the US lead to 21-7, leaving the Kiwis plenty to do, it they hoped to salvage their California dream.

Joe Webber scored only seconds into the second half, but hopes of a comeback were dashed, when Malacchi Esdale restored the margin. Roderick Solo had a try in the dying seconds for New Zealand, but the sidelined conversion miss and the Kiwis ran out of time.

Earlier, two tries to Webber have helped the All Blacks Sevens ease past Samoa 10-7.

After dropping their opening game against Australia, the NZ men needed to bounce back and struck quickly, with Webber bringing up his double before halftime for a 10-0 lead.

In wet conditions, the Kiwis were unable to add to their scoreline after the break, but kept their opponents out until the dying moments, when Tom Maiava finally put them on the board with a try, converted by Taunuu Niulevaea.

In the dying seconds, Samoa could not find a winning score, as they slumped to their second loss of the weekend.
