Jim Paciorek appeared one year in the major leagues. He is the brother of two major leaguers - Tom Paciorek, who had a long career as a player and broadcaster, and John Paciorek, possessor of the perfect batting average. Another brother, Mike Paciorek, as well as nephews Mack Paciorek, Pete Paciorek and Tom Paciorek Jr. also played professional baseball. His son, Joseph Paciorek, was drafted by the Milwaukee Brewers in the 15th round of the 2007 amateur draft and currently plays in their organization.
Jim played for the University of Michigan, where he was an All-American. He was drafted in 1982 by the Milwaukee Brewers, and while he mostly hit over .300 in the Brewers minor league organization, he didn't make it to the big leagues until 1987, when he got 101 at-bats. It was the year when Paul Molitor hit .353 for the Brewers.
He played in Japan from 1988 to 1991 for the Whales (Bay Stars), and in 1992 and 1993 for the Hanshin Tigers. He led the Central League in batting once, and in hits three times. Paciorek had a .315 batting average with 86 home runs and 431 RBIs during the six years.
