Timberlake didn’t post a decision in his two-game stint in the Big Leagues, pitching to an earned run average of 7.50 over six innings of work, with four strikeouts and a whopping nine base on balls.
Only 20 years old at the time, he’d go on to pitch another six years in the Minor Leagues, the last five with the Oakland organization, but never getting another shot in the Majors, retiring for good after the 1975 season.
With those Oakland staffs of Hunter, Blue, Holtzman, etc, I can see why a young starter would have had a hard time breaking into that rotation during the early to mid 1970’s.
