Kinsler was drafted by his home-state Arizona Diamondbacks after high school in the 29th round of the 2000 MLB draft, but did not feel ready for the pros. He opted instead to honour his commitment. He started his college career at Central Arizona College, where he hit .405 with 17 doubles, 37 RBIs, and 24 stolen bases, was named second-team All-ACCAC, and played shortstop alongside future major leaguers Scott Hairston and Rich Harden. The Diamondbacks drafted him again in 2001 (26th round), but he declined to sign because he felt that playing college baseball a little longer would help him develop his game.
