George Brett 1990 Upper Deck
Like many aging superstars that can no longer play the defense that they were once capable of, George Brett made the change to first base.
He did this sooner than most – and it began during the 1987 baseball season, his 13th year in the majors.
In 2,707 career games, Brett played first base in 461 of them. During that span, he compiled a fielding percentage of .993. And while he was never awarded a Gold Glove for his defensively ability at 1B, he was a serviceable aid to the Royals defense.
This card from the 1990 Donruss card captures Mr. Brett fielding his new position.
