In a game against Gonzaga University on March 22, 1968, he pitched a perfect game. He was drafted by the Cleveland Indians in the first round of the secondary phase of the 1968 Major League Baseball Draft, and began his professional career with the AA Waterbury Indians. In 1968, Austin had a 1-8 win-loss record and a 2.73 earned run average (ERA), and in 1969 he split the season between Waterbury, the Indians' rookie team, and the Portland Beavers. With Portland, he had a 5-6 record and a 3.66 ERA in 16 games. After the season, he, along with Rich Hand, were noted as two of the Indians' top pitching prospects.
