Frias went 2-for-5 with a home run and three RBI in a game with Single-A Wilson on Wednesday.
A sizzling stretch that included a 6-for-6 night with Milwaukee's Arizona Complex league club earned Frias a promotion to the Single-A level, and after swiping three bags in his Wilson debut Tuesday, he went yard for the first time a day later. The 18-year-old has firmly put himself on the prospect map, and he has the potential to keep rising up the ranks.
