Born in Tucumcari, New Mexico,[1] he was an outfielder who appeared in 59 Major League games for the Baltimore Orioles (1979–1981).

Corey was Baltimore's second pick in the January 1976 Major League Baseball Draft out of Central Arizona College.

There, Corey again led the league in batting average (.310) and hits (152), and was just two home runs and ten RBIs short of leading the Southern loop in those categories as well.

Hampered by a knee injury,[2] Corey played in only 74 games in 1978 for the Triple-A Rochester Red Wings, but he batted .324 and was primed to take over a spot on the Orioles' American League roster for 1979, but his ongoing knee miseries and a poor performance in spring training[2] earned him a return ticket to Rochester.

He struggled even more with the Red Wings, with his batting average falling to .230, but in his midseason trial with the Orioles, Corey hit his only Major League home run, a two-run shot on July 14 off Paul Splittorff of the Kansas City Royals.
