Wales became the first team to qualify for the Rugby World Cup quarterfinals while virtually shutting the door on Australia’s hopes and putting the Wallabies in danger of their worst-ever showing. The Welsh won by a record 40-6, executing a low-risk, disciplined gameplan and crucifying the many Australian mistakes in Lyon. The Wallabies, winners in 1991 and 1999, have never missed the quarterfinals but losing consecutive pool games for the first time in 36 years left their fate in the hands of their Pacific neighbor Fiji, which upended them last week.
