Skok was selected to the All-Star team in both the Eastern League (1971) and the International League (1972)[2] before his 1973 trial with the Red Sox. Afterwards, he spent the full seasons of 1974–1975 in the Minor Leagues.
Before the 1976 season, Skok was sent by Boston along with Juan Beníquez and Steve Barr to Texas in the same transaction that brought Ferguson Jenkins to the Red Sox. He then split the season between the Rangers and their Triple-A Sacramento Solons affiliate, and was released and out of baseball for 1977.
Skok signed with the Braves as a free agent in 1978 and appeared in 87 games over the 1978–1979 campaigns.
