Konuszewski attended Bridgeport High School in Bridgeport, Michigan where he played baseball, basketball and football.[2] As a junior in 1988, he had an earned run average of 1.47 followed by a 0.78 ERA in 1989. Over his final two seasons of high school he tallied 187 strikeouts in 129 innings. He was named all-state as both a junior and a senior and won multiple Michigan baseball player of the year awards.[3]
Konuszewski was drafted again in 1992, this time in the seventh round by the Pittsburgh Pirates. Konuszewski began his professional career in Pittsburgh's farm system. He was pitching what he considered to be his "best [season] as a professional pitcher" in 1994 when his progress was interrupted by the 1994–95 Major League Baseball strike.[4] That offseason, he pitched in the Arizona Fall League where he had the distinction of striking out Scottsdale Scorpions outfielder Michael Jordan in a nationally televised game.[3]
On August 4, 1995, Konuszewski relieved Steve Parris in his first and final Major League Baseball game. Konuszewski faced five Houston Astros batters, among them future Hall of FamerCraig Biggio. Konuszewski allowed four of them to reach base before manager Jim Leyland pulled him from the game. By 1997, Konuszewski was relegated to Double-A at 26 years old. After 15 games that season, he asked for his release and quietly retired.[4]
