Taylor Phinney wins world title

MELBOURNE, Australia -- American cyclist Taylor Phinney won the men's under-23 time trial Wednesday, adding to his growing list of world championship titles.

Phinney completed the 20.4-mile course in 42 minutes, 50.29 seconds, beating Australian Luke Durbridge by less than two seconds on the opening day of the world road cycling championships.

The 20-year-old Phinney won his second individual world pursuit championship earlier this year and was the heavy favorite coming into the race. His victory comes about a week after he signed to race with BMC as a professional.

Olympic silver medalist Emma Pooley of Britain won the women's time trial, beating German veteran Judith Arndt by more than 15 seconds. Amber Neben of the U.S. finished fourth.

The world championships run through Sunday.
