A three-year letterman at Canyon del Oro High School that led his team to victory in the 1997 Arizona High School State Championship and a national ranking in the Top 25, Shelley was a two-time Arizona Republic state player of the year. Shelley finished his high school career setting city and school records for home runs in a season (13) and career (26).
Shelley spent three years at the University of Arizona shattering all of the school home run records and leaving as a first team All-American. After hitting 20 home runs his freshman year and earning first team Freshman All- American honors in 1999, Shelley went on to break the career record of 36 in only his second year. In 2001 Shelley had a season that earned him first team All-American honors as he led the Pac-10 in home runs (24) and runs batted in (78). His 24 home runs that season are an Arizona record, and a mark that still hasn’t been reached in the Pac-12 since he did it that year. He left with 55 home runs, which still stands as the Arizona record and 5th best in Pac-12 history.
