About Roy Sievers
Roy Sievers was a slugging first baseman/left fielder who broke in as the American League's first-ever Rookie of the Year in 1949 with the St. Louis Browns. After injuries slowed him, he found his greatest success with the Washington Senators (1954-1959), averaging 30 home runs a year and becoming one of the AL's most feared power hitters. His finest season came in 1957, when he led the league in home runs (42), RBI (114), extra-base hits (70), and total bases (331) while hitting .301, finishing third in AL MVP voting behind Mickey Mantle and Ted Williams. A five-time All-Star, Sievers hit .267 for his career with 318 home runs, 1,703 hits, and 1,147 RBI over 17 seasons (1949-1965) with the Browns, Senators (both the original and expansion franchises), White Sox, and Phillies. This 1959 Topps card, issued across multiple card numbers that season, captures him in his final year as Washington's cleanup hitter before being traded to the White Sox. He died in 2017 at age 90.
