Shelton started his career at Alabama. As a freshman in 2023, he batted .300 with 25 home runs. Due to the departure of coach Bohannon, Shelton entered the transfer portal after the season. He was one of the top targets in the entire portal and was eventually picked up by Florida. He made the switch from 3B to SS once arriving to the Gators where he shined all year. He recently announced he will be returning to Gainesville in 2025 despite being a draft eligible sophomore this past season. He looks to be one of the best, if not, the best SS in the nation and most likely a 1st round draft pick.
