Angels’ Mike Trout is just one of many outstanding young players

Mike Trout’s full value to the Angels isn’t shown in his .342 batting average, eight home runs, 32 runs batted in, 22 stolen bases in 25 tries (through Friday) or even his stellar defense. It’s shown in the Angels’ major league-best win-loss record since he was added to the roster April 28.

Trout is a leading contender for rookie of the year in the American League. Deputy Sports Editor Mike Hiserman takes a look at other top rookies, listed in alphabetical order:
