In 1904, Taylor set a major league record by pitching 39 consecutive complete games. Taylor actually threw 187 consecutive complete games between June 1901 and August 1906,[2] but this streak was interrupted by 15 additional relief appearances. Thus Taylor appeared in 202 consecutive games without being relieved himself.
Thus he was part of the great 1906 Cubs; that year the ERA for the entire pitching staff was 1.76. He also contributed to the World Series-winning season in 1907.
Taylor was an above-average hitting pitcher in his major-league career, posting a .222 batting average (236-for-1063) with 110 runs, 2 home runs and 88 RBI. He also drew 66 bases on balls.
