George Spriggs was pictured, hatless in a Pirates uniform, as a Red Sox Rookie Star in the 1968 Topps set. Acquired in the Rule V draft, he instead was returned to the Pirates for the 1968 season at the end of spring training, and spent the entire year in the minors. Purchased by the fledgling Royals in October of 1968, he would return to the majors in Kansas City.
Here is a Flexibell file shot from his 1968 spring with the Red Sox, running alongside Jose Tartabull.
