Hartzell pitched for six years in the majors, finishing with a 27-39 lifetime record. He came up with the California Angels in 1976 and won seven games while posting a 2.77 ERA in 37 games. The season was arguably his best as his ERA would go down as his career low and he pitched the only two shutouts of his career that season. He won eight games the next year, but lost 12. Hartzell pitched one more year for California before joining the Minnesota Twins in 1979. He pitched in 28 games for the Twins that year, mostly in relief, but was released prior to the start of the 1980 campaign. Hartzell pitched in six games for the Baltimore Orioles that season, then went back to the minors in 1981. He did not pitch at all the next two years due to arm injuries. He returned to the majors with the Milwaukee Brewers in 1984, but lasted just four games in what would be the last big-league action of his career.
Hartzell won two games in one day for the Angels on June 26, 1977 against the Texas Rangers at Anaheim Stadium. He pitched two innings of relief in the first game to get the win, then threw another 1-and-2/3 innings in the second game of the double-header for the win. California won both games 4-3.
Hartzell is a member of the Lehigh University Athletic Hall of Fame.
