Jaworowski was a solid hitting first baseman/third baseman at the University of Missouri-Columbia, and later with the Minnesota Twins farm system. The founder and president of the Rawlings Tigers Baseball Club, Aaron launched the team in 2011. The Rawlings Tiges are now considered the premier baseball club in the United States, with over 150 teams in 24 states. He is also the founder of Balls-n-Strikes, which was established in 1999. Jaworowski is an active board member of Midwest Premier Baseball and American Premier Baseball.

Drafted by the Twins in 1997 while playing at Mizzou – where he earned All-America honors - he was featured on the top 100 Prospects List by Baseball America. During the summer of 1997, Aaron led the Appalachian League in RBIs and finished second in home runs. He also led his Twins team in RBIs, home runs, doubles, extra base hits and at-bats. Jaworowski played four years in the Twins’ and New York Yankees’ farm systems. He also played for the River City Rascals and hit the first home run at the team’s T.R. Hughes Ballpark.

He still holds the single-season records for RBIs, doubles, extra base hits and total bases at Mizzou, where he spent three seasons before signing with the Twins. He ranks in the top five in Mizzou history in single season at-bats. In 1996, he was named the Mizzou Athlete of the Year and was twice named the Mizuno National Player of the Week. He was the Big 12 Tournament MVP after posting 15 hits in 20 at-bats with 15 RBIs and six doubles, breaking Robin Ventura’s tournament record for hits and RBIs. That year, he had four home runs in a doubleheader and eight consecutive hits in a doubleheader. In 1995, Aaron hit a walk-off home run against Oklahoma State, the top-ranked team in America at the time.

Aaron starred for Lafayette High School’s baseball team.
