Twenty wins in a single season is a truly a magical plateau. Jim Bouton wrote in his classic book Ball Four , "If you had a pill that would guarantee a pitcher twenty wins, but might take five years off his life, he'd take it."
Baseball Almanac is pleased to present the pitchers from 1951 through 1975 who are members of the National League 20 Wins Club.

"Whenever I threw a home-run ball, and Lord knows I threw plenty of them, I usually knew as soon as I saw that full swing what I had done wrong." - Robin Roberts (five time twenty-game winner in the National League)
In Chronological Order
In 1955 , Robin Roberts gave up forty-one (41) home runs during a twenty (20) win season. This is the most by National League pitcher during a twenty (20) win season and in 1979 Phil Niekro tied that long ball mark.
Which National League pitcher allowed the fewest home runs during a twenty (20) win season? Jesse Tannehill ( 1902 ), Deacon Phillippe ( 1905 ), Jake Weimer ( 1906 ) and Vic Willis ( 1906 ) did not allow any.
