Known for his control and ability to keep hitters off balance, he was a workhorse on the mound, regularly pitching over 200 innings per season. His best season statistically came in 1969 when he recorded a 20-15 win-loss record with a 2.66 ERA, further establishing himself as a reliable starter.

In 1974, Osteen was traded to the Houston Astros, where he continued to demonstrate his pitching prowess. Although his time with the Astros was brief, he provided veteran leadership and experience to the team's pitching staff. He later played for the St. Louis Cardinals and the Chicago White Sox before retiring in 1975.
