An innovator in promotions and marketing, Vonachen purchased the Peoria Suns in late 1983 and turned the Midwest League franchise into a 1980s powerhouse after renaming the team the Chiefs in 1984. Then, the Chiefs became an affiliate of the
Chicago Cubs from 1985–1995, moved to the
St. Louis Cardinals from 1996–2004, rejoined the Cubs from 2005 through 2012, and returned to St. Louis in 2013. Stressing first-class facilities and a belief that fans should have fun at the ball park, Vonachen, with the cooperation of the Peoria Park District, turned Meinen Field into such an attractive park that it won the 1987 Midwest League Gold Award for the most outstanding facility in the league. During this period, the Class-A Chiefs were led by future big leaguers as
Joe Girardi,
Mark Grace,
Greg Maddux,
Derrick May,
Rafael Palmeiro,
Dwight Smith,
Jerome Walton and
Rick Wilkins, among others, being managed by
Joe Maddon (1984),
Pete Mackanin (1985–1986),
Jim Tracy (1987–1988) and
Brad Mills (1989). On April 18, 1992, Meinen Field was renamed
Pete Vonachen Stadium. Then Vonachen returned to the Chiefs in September 1994, leading a new investor group and serving as their
general manager through 1998. During his second stint with the club, Vonachen helped the Chiefs secure the site and raised money for the development of a new downtown stadium, while attendance grew by nearly 20,000 fans. After retiring, he turned over the reins to his son Rocky Vonachen in 1998. In 2002, the Chiefs moved into their new ballpark
O'Brien Field, won their first ever Midwest League Championship, and obliterated the franchise attendance mark. In 2009, the site was renamed Peoria Chiefs Stadium. ==Honors==
