3. Noodles Hahn, Reds left-handed pitcher (44.5 WAR)
Noodles Hahn debuted for the Cincinnati Reds in 1899 and spent almost his entire major league career in the Queen City. Seven of Hahn's eight seasons were spent in a Reds uniform, but the left-hander finished his career in the Big Apple as a member of the New York Highlanders in 1906.
During his first three seasons in Cincinnati, Hahn led the league in strikeouts. In 1901, Hahn not only led the league in punch outs, but also innings pitched and complete games. Hahn was on the bump for 375 innings that season.
For those who are curious, the major league record is Will White with 680 inning pitched in 1879. Just for reference, Graham Ashcraft led all Reds pitchers this season 145 innings on the mound.
Hahn won at least 20 games in four of the seven years that he pitched in Cincinnati and eclipsed 300 innings pitched four different times. Unfortunately, according to SABR.org, this ironman mentality caused Hahn to suffer a dead arm at the age of 26.
Noodles Hahn finished his career with over 2,000 innings pitched in just eight seasons. Hahn's career-ERA with the Reds was a measly 2.52. That'll do. As for his real name, it's actually Frank George Hahn. The nickname Noodles has a few different origin stories, but regardless, he was one of the best pitchers in Reds history.
