Women's sevens wins fans with action-packed finale

Women's rugby sevens has a bright future at the Olympics, Australia's coach Tim Walsh said after his side won the sport's debut gold in Rio.

Australia capitalized on the sin-binning of star New Zealand winger Portia Woodman to turn the screws and notch a 24-17 victory at a raucous Deodoro Stadium on Monday.

Rugby sevens was accepted for the Rio Olympics in 2009, and Walsh said he believed the three days of entertainment from the 12 teams proved rugby was worth its place - despite a large gap between the top and bottom sides.
