Hebert was a star pitcher for Jack Barry’s Crusader baseball teams of 1928-30. He posted a record on the mound of 22-3 and played on several Eastern Intercollegiate Championship teams. In 1929 Hebert became the staff ace after fellow Hall of Famer Bots Nekola signed to play professionally. He turned down an offer by the Philadelphia Athletics to remain in college baseball and obtain his degree. Herbert was 11-0 in his starts in the '29 season, finishing his year by beating both Providence and Boston College on two days rest to clinch the Eastern Intercollegiate title.
