Federer beats Nadal (in World Cup and Wimbledon seedings)

The greatest rivalry in tennis took to the soccer pitch Wednesday when Roger Federer's native Switzerland faced off against Rafael Nadal's beloved Spanish national team in a World Cup pool game. And for the first time in what seems like a while, Federer came out on top.

The Swiss pulled off the biggest upset of the 2010 World Cup on Wednesday afternoon in South Africa, stunning top-ranked Spain 1-0. Federer and Nadal are passionate supporters of their national teams. Nadal, in particular, is known as a big soccer fan and was said to have celebrated into the night against his coach's wishes in 2008 when Spain won the Euro Cup during Wimbledon.

The small amount of soccer pride wasn't the only good news for Federer on Wednesday. In defiance of the current ATP rankings, Wimbledon organizers installed Federer as the No. 1 seed at next week's grass court Grand Slam. Nadal is the No. 2 seed, a flip-flop of the current rankings. Wimbledon is the only tournament that breaks away from the rankings when determining seeds. It was an easy, obvious decision — Federer has won six of the past seven events at the All England Club — and one that matters in stature only, as the pair would have been on opposite sides of the draw regardless.

Federer and Nadal will learn their respective Wimbledon draws on Friday. As defending champion, Federer will have the honor of playing in the first match of the tournament on Centre Court. He'll have more incentive than usual to make quick work of his first-round opponent. Switzerland's second match kicks off at 3 p.m. London time on Monday.
