Germany's men and women's indoor hockey teams showed their strength and class to jump immediately to the top of their respective points tables on the opening day of the World Games 2005 in Duisburg.

With indoor hockey appearing at the World Games as an invitation sport in the German industrial city, the home team's men showed their class with an 18-2 demolition of Canada.

Germany piled on nine goals in each half in an entertaining and at times ruthless display that further enhances their overwhelming favouritism for the title. Oliver Domke scored four goals for Germany with Christian Mayerhoefer, Philipp Sunkel and Christoph Bechmann each contributing a hat trick.

Scott Tupper scored both of Canada's goals but it was not even close to overcoming the might of the reigning indoor world champions.

While the first men's match on day one was a one-way contest, the second between Switzerland and Czech Republic was a tight and exciting clash.

Switzerland raced to a 3-0 lead before Czech Republic pegged back the deficit with three goals in four minutes late in the first half.

After scores were tied at 3-3 at half time, the teams traded goals in a high-stakes second half until Switzerland edged ahead in the final three minutes to win an even match 6-5. Michael Kloter starred for Switzerland with three goals and his third was the one that sealed his team's vital win.

Given the brief nature of the tournament (three days), Switzerland are now favoured to face Germany in the final, but all teams but play two more matches before the qualifers for Sunday's final is determined.

In the women's competition, Germany join their male counterparts at the top of the points table after recording an expected 5-3 victory over Czech Republic.

However Germany had to work hard throughout the opening 20 minutes and into the second half to overcome their opponent.

Czech Republic led twice in the first 10 minutes but couldn't maintain their momentum as the experience of the home team prevailed. Anneke Boehmert's acute goal sense netted her two goals - one in each half ÔÇô in an impressive individual performance.

In the other women's match, Belarus came from 2-1 behind at half time to overrun Lithuania 3-2. Each team had chances to gain the advantage in the second half but Belarus gradually wrested control of the match and were deserving winner.

As with the Switzerland men, Belarus are now in the favoured to move into Sunday's final, but they face two tough matches against Czech Republic and Germany on Saturday.

Each team will play two matches each on Saturday before the top two meet in Sunday's final.
