The Minnesota Thunder soccer team plays the first game of the A-League Western Conference finals Friday night in Seattle, and the deciding second game of the total-goal series takes place Sunday at the National Sports Center in Blaine. While the team has played most of the games in its 14 seasons in Blaine and is obligated to finish out its season there, it's announced it will move to a different venue in 2004. Jim Froslid is the team's president and general manager. He says the Thunder may play second fiddle to the Twins and the Vikings, but interest in soccer is growing.
