The next two years would not be good for Faber. He missed most of 1918 due to serving in World War I, and he was hurt for much of 1919. That kept him out of the World Series, the year of the Black Sox scandal, and it is believed that he would have been above reproach. Had he been able to pitch, it could have been an entirely different result.
In the early 20s, the White Sox were a tarnished team, but Faber would be at his best. From 1920 to 1922, he won at least 21 Games, and always had an ERA under 3.00. Faber won the ERA and WHIP titles in both 1921 and 1922, and in those two seasons, he was among the game's elite Pitchers.
From 1923 to 1933, Faber was up and down with his stuff, but his dugout presence made him invaluable to the team. He would be released in 1933, and he retired shortly after.
Over his career, Faber would post a 254-213 record with 4,086.2 Innings, a 3.15 ERA, and 1,471 Strikeouts.Faber would enter Baseball Hall of Fame in 1964.
