Dave Steffen of Flat Rock, Michigan was inducted into the Player Category in 2004 in Fort Myers, Florida. Nicknamed "The Daffy One" for his colorful antics on and off the field, the 6'4" 300lb plus Steffen was an all around athlete earning all state honors in baseball, football, and wrestling at Flat Rock High School. He spurned a football scholarship at the University of Michigan to sign with the Detroit Tigers as a high draft pick. The fire balling right hander made the major league roster only to suffer an arm injury in spring training. His last ditch effort with the Chicago White Sox also failed and he turned to softball.

During a 16 year career at the major level of softball he played with South Western Industries of Taylor, MI; Coors of Detroit, MI; Steele's Sports of Brook Park, OH; Marlton Trucking of Portland, OR; Lilly Air of Chicago, IL; Bell Corp. of Tampa, FL; Ritch's/Kirks of Harrisburg, NC; Converter's of Kinston, NC and Ritch's Superior TPS of Windsor Locks, CT.

Steffen appeared in 13 ISA World Series and won 6 titles, including 5 straight with Ritch's-Superior. In 1993 at Gainesville, GA he was named the series MVP posting an .818 batting average and was the home run champion with 13. He was also named to 6 other ISA all world teams.

In 2002 Dave played an integral role in bringing the ISA to is hometown complex in Flat Rock. All leagues and tournaments are now sanctioned with ISA. Dave and his wife Tammy have two sons Casey and Kyle.
