Dave McNally debuted at 19 for Baltimore in 1962, and he would spend the next few years as a mid-level starter and helped Baltimore win the 1966 World Series. From 1968 to 1971, McNally was a three-time All-Star, and he would never have less than 20 Wins, and he led the American League in that stat with 24. That year, he again won a World Series Ring as the Orioles won it all. In 1970 he finished second in Cy Young voting, and he was fourth the year before and after. McNally had two more 16 Win Seasons for Baltimore.
Best known for his sideburns and that inexplicable (actually, many think they can explain it) 50 Home Run Season in 1996, Brady Anderson played 14 seasons for the Orioles.
Paul Blair is another one of the great defensive gems that the Orioles had in the 1960s and 1970s, and he patrolled the Centerfield position at an elite level for years.
The Baltimore Orioles of the 1960s and 1970s were loaded with defensive talent, and while Brooks Robinson may have received the most attention, Mark Belanger could match him play for play.
