BLOEMFONTEIN, South Africa, June 24 (Reuters) - United States scored their greatest win for almost 60 years by beating European champions Spain 2-0 on Wednesday to reach the final of the Confederations Cup.

Goals from Jozy Altidore and Clint Dempsey ended Spain's world record run of 15 successive victories and their 35-match unbeaten sequence, a world record streak they share with Brazil, and caused one of the biggest soccer upsets in years.

However, the match ended in bitter-sweet agony for U.S. coach Bob Bradley when his son Michael, who had a brilliant game in midfield, was sent off three minutes from time.
