Baltimore Orioles were the last team to have four 20 game winners in one season?

The Baltimore Orioles achieved the remarkable feat of having four pitchers win 20 games in a single season in 1971. The pitchers were Jim Palmer, Mike Cuellar, Dave McNally, and Pat Dobson. This accomplishment is notable in Major League Baseball history, as it demonstrates the team's exceptional pitching depth during that era. Since then, no other team has matched this achievement.
