The 2012 MLB season was a big one for rookie phenoms. Los Angeles Angels outfielder Mike Trout demolished everything he saw en route to finishing second in AL MVP voting and first in AL Rookie of the Year voting. Washington Nationals counterpart Bryce Harper won the National League Rookie of the Year award in his age-19 season.
The American League also saw Cuban defector Yoenis Cespedes make a good name for himself with the Oakland Athletics. Their division rivals, the Texas Rangers, had a star of their own in Japanese import Yu Darvish, who was impressive in his debut campaign in the United States.
In the National League, the top rookie pitcher was Wade Miley of the Arizona Diamondbacks, who nearly beat Harper for the NL Rookie of the Year title. Todd Frazier finished third, emerging as a viable option for the Cincinnati Reds.
However, some other rookies flew a little under the radar in terms of their overall performances, either due to more limited playing time or just not being in the right situation. But with a new season ahead of them, here are some of those names set for stronger second seasons.
