About Dave Leonhard
Dave Leonhard went 2-3 with a 2.83 ERA over 54 innings for the 1971 Baltimore Orioles. He then pitched an inning in the World Series, which Pittsburgh won in seven games. His 1972 Topps card, #527, falls in the fifth series with Baltimore. He made 14 relief appearances in 1972 and pitched his last major league game on September 20.
Dave Leonhard was a right-handed pitcher who spent his entire six-year major league career, 1967 through 1972, with the Baltimore Orioles during the club's late-1960s and early-1970s pennant-winning run. A Johns Hopkins University graduate who briefly taught high school history before signing with Baltimore, he worked his way up through the minor leagues, winning the International League Pitcher of the Year Award with Rochester in 1967 before his September call-up. He served the Orioles as both a starter and a reliever, posting his best season in 1969 with a 7-4 record and a 2.49 ERA over a career-high 37 appearances. He appeared in the 1969 and 1971 World Series and was on Baltimore's roster for its 1970 championship, though he did not pitch in that series. His career totals were 16-14 with a 3.15 ERA over 337 innings. He struck out 146 and saved five games. He and teammate Jim Palmer were roommates, and Palmer called him his best friend on the team. Leonhard and his wife Doris opened a garden center in Beverly, Massachusetts, in 1975.
