It was the 2001 Great Lakes Classic, against Steve Wilson. Great show. It's on disc 48. Steve Wilson threw a gutter ball in one of the first frames of the show during the wildcard match.
The Weber/Haugen match was the title match at the 2001 Louisville Open, Pete shot 289 to Haugen's 279. It's easy to get them confused because Steve Wilson looks so much like Mike Haugen. Also they were about six weeks apart.
