Mike Trout of the Los Angeles Angels became the youngest American League rookie of the year on Monday and Bryce Harper of the Washington Nationals was voted the second-youngest winner of the NL honour.
Trout, who turned 21 on Aug. 7, received all 28 first-place votes from the Baseball Writers' Association of America's AL panel. The centre-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).
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.
Harper turned 20 on Oct. 16. The outfielder got 16 of 32 first-place votes. Harper was the top pick of the 2010 amateur draft and batted .270 with 22 home runs and 59 RBIs.
