Opening races of America's Cup challenger series postponed

The opening races in the America's Cup challenger semifinals on Bermuda's Great Sound were postponed Sunday because the wind didn't reach the required six knots for the foiling 50-foot catamarans to race in.

Regatta director Iain Murray says the forecast looks better for Monday.

Two races are scheduled in each of the matchups, between Emirates Team New Zealand and Britain's Land Rover BAR, and Sweden's Artemis Racing and SoftBank Team Japan.

The winners of the best-of-nine series will meet for the right to face two-time defending champion Oracle Team USA in the America's Cup match beginning June 17.
