1970 Topps #370 Tommy Harper
About Tommy Harper
Harper hit .235 with 9 home runs and 41 RBI for Seattle in 1969. He also led the majors in stolen bases, 11 more than anyone else. In the Pilots' first home game he singled and stole second, the first home theft in franchise history. Card #370, a third-series issue, lists him with the Seattle Pilots, a club declared bankrupt on April 1, 1970 and moved to Milwaukee as the Brewers.
Tommy Harper signed with Cincinnati in 1960, scouted by Bobby Mattick, and reached the majors in 1962 as a third baseman before moving to the outfield. Across 15 seasons (1962-1976) with the Reds, Indians, Pilots/Brewers, Red Sox, Angels, Athletics and Orioles he hit .257 with 1,609 hits in 1,810 games. He also hit 146 home runs, drove in 567 runs and stole 408 bases. In 1969 he stole 73 bases for the expansion Seattle Pilots, the most by an American Leaguer since Ty Cobb's 96 in 1915. In 1970 with Milwaukee he became the fifth major leaguer to join the 30-30 club (31 home runs, 38 steals) and made his only All-Star team. He led the league again in 1973 with 54 steals, a Red Sox record that stood until 2009, and was voted the club's Most Valuable Player. Known as "Tailwind Tommy," he later coached for Boston and Montreal and entered the Red Sox Hall of Fame in 2010.

What is the 1970 Topps #370 card?
It is card #370 of the 720-card 1970 Topps Baseball set, picturing Tommy Harper of the Seattle Pilots.
Why does this card say Seattle Pilots?
Because the card prints the Seattle Pilots, and it is correct as printed: the franchise played the 1970 season as the Milwaukee Brewers, but thirty 1970 Topps cards print the Pilots - the #713 team card, #556 Dave Bristol's manager card, the #88 Pilots Rookie Stars and twenty-seven player cards. 1970 Topps is the second and last Topps flagship set with Seattle Pilots cards.
