After leading Bay City, Michigan All Saints Central High School to a baseball state championship in 1981,[1] Miller was selected in the 24th round of the 1981 Major League Baseball draft by the Cleveland Indians, but opted to attended Oral Roberts University, instead.

He hit his first career home run on July 1 off the Houston Astros' Jim Deshaies, and went 3-for-6 in the extra innings loss to bring his average above .200 for the first time all season.

That idea was pretty much abandoned after the Mets acquired Daryl Boston from the Chicago White Sox,[6] however, 1990 turned out to be the one full season of Miller's career in which he logged more innings in the outfield (423.1) than the infield (69).

His best season as a Met turned out to be 1991, when he batted .280 with four home runs and 23 RBIs, all career highs to that point.

At the Winter meetings, he was part of a blockbuster deal in which he, Gregg Jefferies and Kevin McReynolds were traded to the Kansas City Royals for two time Cy Young Award winner Bret Saberhagen and infielder Bill Pecota.

[8] Miller was in left field that day, but he was shifted back to his natural position at second base by the end of April to replace the slumping Terry Shumpert.

During the off-season, the Royals dealt Jeffries to the St. Louis Cardinals, and shifted Miller to third.

Among his notable clients with Aces Inc. are David Wright, Brandon Inge and Scott Rolen.
