Classic White Sox cap circa 1963 was worn to the mound by one tough cookie, Puerto Rican fireballer Juan Pizarro, who in '62 threw two no-hitters and in '63 and '64 went a combined 35-17 with ERAs well under 3.00. Blue cap has the old-style diagonal "SOX" in white, and a handwritten "32" is on the underside of the bill. Extensive wear with abundant soil and sweat staining.
