Davis was born in Longview, Texas. He has an older sister, Jennifer. While he was in high school, his parents divorced. Davis attended Longview High School, playing shortstop on the school's varsity baseball team and pitching as well before graduating in 2004. He was originally chosen by the New York Yankees as the third-to-last pick of the 2004 Major League Baseball (MLB) Draft (1,496th overall in the 50th round). However, he did not sign and opted to attend Navarro Junior College in Texas instead, beginning in 2005. At Navarro, he was used as a third baseman and first baseman. He was once again drafted, by the Los Angeles Angels of Anaheim, in the 2005 MLB draft, however he did not sign. He was named a preseason JUCO All-American by Baseball America in 2006, earning Region XIV East Zone Most Valuable Player honors. That year with Navarro, he hit 17 home runs, one of which hit a retail building 100 feet away beyond the 380 sign on the outfield fence. Davis was then drafted again, this time by the Texas Rangers in the fifth round of the 2006 MLB draft. Davis was inducted to the Navarro College athletic hall of fame in 2021.
