Reggie Jackson Oakland A'sOn June 18, 1972, colorful Oakland A’s owner Charlie Finley holds baseball’s first ever “Mustache Day.” Finley agrees to pay $300 to each of his players for growing mustaches by Father’s Day and all do except Vida Blue, who is still bitter about his recent contract negotiations with the team owner. Reggie Jackson had started the trend by reporting to spring training with a mustache – the first major leaguer to do so since Wally Schang in 1914.
