Born in Terrell, Texas, Morehart attended Austin College and played two seasons for the Chicago White Sox before being traded (along with catcher Johnny Grabowski) for infielder Aaron Ward in January 1927; Morehart was therefore a member of the 1927 New York Yankees, a team often considered the greatest ever. As a rookie with Chicago, Morehart set a record with nine hits during a doubleheader.

Morehart died in Dallas, Texas on January 13, 1989. He was one of the last surviving players to have played with Babe Ruth and Lou Gehrig.
