Primarily a second baseman and shortstop, Oceak spent his entire playing career (1932–40; 1942–43; 1946–47) in the lower minor leagues, briefly as a member of the Yankees' farm system.
Two years later, as manager of the Beaver Falls Browns of the Class D Pennsylvania State Association, Oceak was suspended by Commissioner of Baseball Kenesaw Mountain Landis for the entire 1941 season for an assault on an umpire.
[1] However, Oceak resumed his playing and managing careers in 1942 with the Oil City Oilers of the PSA, his first assignment in the Pirates' organization, where he would spend most of the rest of his baseball life.
The bulk of his managing career, as in his playing days, took place in the lower minors, until 1957 when he was named skipper of the Columbus Jets of the Triple-A International League, one of the Pirates' two top-tier farm clubs.
Oceak then spent one season, 1965, with the Cincinnati Reds as a coach under Dick Sisler before returning to Pittsburgh as a minor league manager at the Class A and Double-A levels from 1966–69.
