Notes Nichols' and Radbourn's streaks date from the start of their careers; the only pitchers to start their careers with streaks of seven consecutive seasons of 20 wins. Winning percentage is generally computed to the thousandths place. When necessary, the percentage is computed to greater precision to establish a true order. Minimum of 200 decisions (wins + losses). Vic Rasci's record of 132–66 (0.667) does not meet the minimum number of decisions to qualify for this list; however, when he is credited with two additional losses, his percentage drops to 0.660, which still qualifies him for this listing. Minimum of 15 decisions. Sutcliffe started the 1984 season with a record 4–5 with the Cleveland Indians of the American League before being traded to the Cubs.
