By contrast, pitching was a strength for the Baltimore Orioles as manager Earl Weaver had three, healthy 20-game winners. Mike Cuellar (24–8, 3.48 ERA), Dave McNally (24–9, 3.22) and future Hall of Famer Jim Palmer (20–10, 2.71) were all well-rested and ready for the Series. Weaver balanced good pitching with the hitting of 1970 AL MVP Boog Powell (35, 114, .297), Merv Rettenmund (18, 58, .322), as well as future Hall of Famers Frank Robinson (25, 78, .306) and Brooks Robinson (18, 94, .276). The Orioles led the AL in most runs scored (792), fewest runs allowed (574), complete games by starting pitchers (60), lowest team earned run average (3.15) and they were second in the AL in fielding percentage (.981) establishing themselves as the most dominant Orioles team in the modern era.. Who were the 3 20-game winners?
