University of Missouri Tigers coach Tim Jamieson spotted him in a summer league, and convinced him to head east for his junior year. Jamieson said, "I saw him take ground balls and thought, defensively, he was as good a middle infielder as I had ever seen. As for his bat, I didn't really care." While there, Kinsler had a .335 batting average, .416 on-base percentage, and .536 slugging percentage, with 16 steals in 17 attempts. He was named to the All-Big 12 Conference second team. Jamieson noted, "From the day Ian stepped through the doors here, you could see it on his face: He was on a mission."
