The Rockies catcher, who set a handful of records with the club, was not a finalist for National League Rookie of the Year thanks to a MLB-high 21 passed balls behind the plate in 2012.
Instead, Rosario, 23, was surpassed by Diamondbacks starter Wade Miley, Nationals outfielder Bryce Harper and the Reds’ Todd Frazier.
Miley and Harper are the favorites to win the award.
In the end, his offense alone couldn’t help the Rockies notch their second year-end award, as outfielder Carlos Gonzalez recently won the Gold Glove.
Rosario hit a Rockie-rookie record 28 home runs while batting .270 this season.
