Australia's Robbie McEwen tightened his grip of the Tour Down Under after a sprint finish secured a second stage win and increased his overall lead.
Robbie McEwen wins second stage of Tour Down Under
The 32-year-old Davitamon-Lotto rider beat Italian Paride Grillo to the line, with Australia's Allan Davis in third.
Great Britain's Bradley Wiggins put in another steady ride to finish among the pack after the 150km stage.
The triple Olympic medallist, using the race to prepare for the European season, is 12 seconds off the lead.
McEwen, two-time winner and current holder of the Tour de France green points jersey, has never won an overall race but is now well placed to take control in the remaining stages.
But he will have to keep an eye on compatriot Stuart O'Grady. The two-time winner of the event is yet to make a charge but has stated his intention to go all out for victory.
David O'Loughlin from Ireland secured the black jersey in the stage which took the riders from Salisbury to Tanunda.
The black jersey is given to the rider who is judged to have instigated the most attacks and breakaways.
