The story on this card
Card 233 in the 1967 Topps set is a League Leaders card recapping the American League ERA race from the prior season, naming the top three finishers together: White Sox teammates Gary Peters and Joe Horlen, plus the Indians' Steve Hargan. Peters topped the league at 1.98 for Chicago, Horlen was close behind at 2.43, and Hargan rounded out the trio after a strong first full season in the Cleveland rotation, going 13-10 with a 2.48 ERA and his first career shutout, a seven-hitter over the Twins. The card ties two of the era's stingiest White Sox arms to a rising young Indians starter, spotlighting a category the light-hitting Chicago staff dominated by pitching to soft contact and low run support rather than overpowering strikeout totals.
Gary Peters - White Sox lefty who needed seven minor-league seasons and four short call-ups before an emergency start stuck in 1963, the year he led the AL in ERA and won Rookie of the Year; he later tied for the league lead in wins. A soft-spoken right-hander from San Antonio, Joel Horlen anchored the Chicago White Sox rotation through the 1960s with a hard curve and a stingy ERA, throwing a 1967 no-hitter for a club that could barely score him a run. A Fort Wayne, Indiana native who broke in with Cleveland in 1965, Hargan made his only All-Star team in 1967 after opening the year with consecutive shutouts.
