Baseball:The World Series shifts to Colorado for Game Three tonight, a move the Rockies hope will also bring a shift in momentum as they trail the Boston Red Sox 2-0 in the best-of-seven Major League Baseball championship.

Colorado's Coors Field is unique. Denver's mile-high elevation in the Rocky Mountains means thinner air.

Meanwhile, in American Football, the New York Giants face Miami Dolphins at Wembley Stadium in London tomorrow in the first competitive National Football League game to be played outside North America.
