USOC GETTING TOUGHER: The U.S. Olympic Committee will take a more aggressive approach with its anti-doping strategy, putting more emphasis on testing athletes in high-risk sports such as track and cycling, increasing unannounced testing and pumping more money into research.

Not satisfied with progress being made in the increasingly high-profile fight against doping, the USOC signed a new agreement with the U.S. Anti-Doping Agency through 2010 that gives the USOC a more active role in expanding research.

WIMBLEDON SECURITY: Vehicle blockers were set up in front of gates to the All England Club on Sunday as part of efforts to tighten security at Wimbledon after two foiled car bombings in London and a fiery attack on Glasgow's airport.

Tournament organizers already had stepped up measures in recent days, including more stringent searches of bags carried by people onto the grounds.

"As a result of recent events in London and Glasgow, and further to our own discussions with the police and other authorities, as well as taking into consideration the generally higher security alert level in London and across the country, we have been advised by the police to adopt extra security measures to protect the areas of most risk," All England Club chief executive Ian Ritchie said Sunday.
