Mike Trout of the Los Angeles Angels became the youngest AL Rookie of the Year on Monday and Bryce Harper of the Washington Nationals was voted the second-youngest winner of the NL honor.
Trout, who turned 21 on Aug. 7, received all 28 first-place votes from the Baseball Writers' Association of America's AL panel. The center fielder was the eighth unanimous AL pick and the first since Tampa Bay's Evan Longoria in 2008.
Trout, who hit .326 with 30 homers and 83 RBIs, received the maximum 140 points. Oakland outfielder Yoenis Cespedes was second with 63, followed by Texas pitcher Yu Darvish (46), who joined Trout as the only players listed on every ballot.
Detroit second baseman Lou Whitaker had been the youngest AL winner in 1978, but he was 2 months, 26 days older than Trout when he took home the award.
In addition to Trout and Longoria, the only other unanimous AL winners were Nomar Garciaparra, Derek Jeter, Tim Salmon, Sandy Alomar Jr., Mark McGwire and Carlton Fisk.
