The U.S. got clear rounds from their first three riders in the jump-off. One Canadian rider knocked down a fence, and since Canada only had three riders to the Americans' four, that clinched the U.S. gold.
The U.S. also won team jumping in 2004 in Athens and has two returning combinations on the 2008 team, McLain Ward on Sapphire and Beezie Madden on Authentic.
Ian Millar, riding in his ninth Olympics, forced the jump-off with a clear round on In Style. The team silver is Millar's first Olympic medal.
