High school career
Standridge is the son of Wayne and Donna Standridge of Clay, who home-schooled him until the 10th grade. As a junior he enrolled at Hewitt-Trussville High School, where he made an immediate impact in sports. As a senior pitcher he went 9-1 with a 2.19 ERA. In addition to baseball he competed on the wrestling team and was a standout quarterback and captain of the football team. In his senior season as quarterback, Standridge completed 50 of 95 passes for 689 yards and seven touchdowns in Jack Wood's run-oriented offense. He also rushed for 378 yards and seven more touchdowns. He was a PrepStar All-American, a Birmingham News "Super Senior", and appeared in numerous recruiting lists. He signed a letter of intent for Auburn University, but decided to pursue baseball when he was drafted in the 1st round (31st overall pick) of the 1997 amateur entry draft by the Tampa Bay Devil Rays.
