A junior college transfer in 1991, she came to Arizona in time to help UofA win their first national championship. Show was All Pac-10 First-Team for three consecutive years, and a three-time All-Region honoree. She received second team All-American honors in 1992 and First-Team All-American honors in 1993, as a member of Arizona's second NCAA championship softball team. In three years in the outfield she committed only one error and at the plate she hit .330, .338 and .365 in successive years. She left Arizona listed in the top ten in career batting, hits, runs scored, home runs, and stolen bases, and she is still first in career triples.
