At the 2013 IIHF World Championship, Berra split goaltending duties with Martin Gerber.[1] Berra appeared in four games, winning all four and posting a GAA of 1.00.[20] The unheralded Swiss team went on a "Cinderella run" at the championship, winning their first nine games of the tournament.[21] The ninth win came in the semi-final as Berra led his team to an upset win over the United States.
