Allenby made eight birdies and one bogey in his opening round.
DUBAI, United Arab Emirates (AP) -- Robert Allenby shot a 7-under 65 on Thursday for a one-shot lead after the first round of the Dubai World Championship.
The 38-year-old Australian, who plays mainly on the PGA Tour, had eight birdies and only one bogey on the Earth Course, which is hosting the $7.5 million final event of the European Tour season.
Allenby was one shot ahead of England's Lee Westwood, Chris Woods and Colombian Camilo Villegas, who all shot 66.
When the tournament ends Sunday, the top player on the European Tour's money list will win a $1.5 million bonus from the new Race to Dubai.
Westwood, sitting in second in the race, was two shots ahead of money leader Rory McIlroy of Northern Ireland.
