Unless you're a old Dodger fan, or have researched the "early" Los Angeles Dodgers , you would not know that about Koufax. You are correct about your observation about Sandy. Koufax was wild during the early part of his major league career. Here's a brief look at Koufax's 12 year MLB career:
Sanford "Sandy" Koufax; born
Sanford Braun; December 30, 1935. Koufax was born in
Brooklyn, New York, to a Jewish family. His parents,
Evelyn (née Lichtenstein) and
Jack Braun, divorced when he was three years old. His mother was remarried when he was nine, to
Irving Koufax.
Sandy pitched twelve seasons for the
Brooklyn/Los Angeles Dodgers, from 1955 to 1966.
Koufax, at age 36 in 1972, became the youngest player ever elected to the Baseball Hall of Fame.
Koufax's career peaked with a run of six outstanding years from 1961 to 1966, before arthritis in his left elbow ended his career prematurely at age 30. He was an
All-Star for six seasons
[2] and was the
National League's
Most Valuable Player in
1963. He won three
Cy Young Awards in 1963,
1965, and 1966, by unanimous votes, making him the first three-time Cy Young winner in baseball history and the only one to win three times when one overall award was given for all of major league baseball instead of one award for each league. Koufax also won the NL
Triple Crown for pitchers those same three years by leading the NL in
wins,
strikeouts, and
earned run average.
Koufax was the first major league pitcher to pitch four no-hitters and the eighth pitcher to pitch a
perfect game in baseball history. Despite his comparatively short career, Koufax's 2,396 career strikeouts ranked 7th in history as of his retirement, trailing only
Warren Spahn (2,583) among left-handers. Koufax,
Randy Johnson,
Pedro Martínez, and
Nolan Ryan are the only four pitchers elected to the Hall of Fame who had more strikeouts than innings pitched.
Koufax is also remembered as one of the outstanding
Jewish athletes in American sports. His decision not to pitch Game 1 of the
1965 World Series because it fell on
Yom Kippur garnered national attention as an example of conflict between professional pressures and personal beliefs.
Career overall -
Koufax made his major league debut on June 24, 1955 against the Milwaukee Braves. After the 1966 world series, Koufax announced his retirement due to his arthritic condition
In his 12-season career, Koufax had a 165–87 record with a 2.76 ERA, 2,396 strikeouts, 137 complete games, and 40 shutouts. He was the first pitcher to average fewer than seven
hits allowed per nine
innings pitched in his career (6.79) and to strike out more than nine batters (9.28) per nine innings pitched in his career. He also became the 2nd pitcher in baseball history to have two games with 18 or more strikeouts, and the first to have eight games with 15 or more strikeouts. In his last ten seasons, from 1957 to 1966, batters hit .203 against Koufax, with a .271
on-base percentage and a .315
slugging average.
Koufax was the first pitcher to win multiple Cy Young Awards, as well as the first pitcher to win a Cy Young Award by a unanimous vote. He is also the only pitcher to win three Cy Young Awards in the era in which the award was presented to one pitcher across the board, rather than one in each major league. Koufax was special.
We knew it then as we watched him, just like the folks in Cincinnati knew they were watching a future HOF player in
Johnny Bench. It was a pleasure and a privilege to watch Koufax during his "glory" years.
The only thing that rivaled Koufax's glory years here was "
Fernando-mania",

but that's another story for another time. Koufax was part of four world series championships in '55, '59, '63 & '65.
From 1961-1965, Koufax had no peer. He was one of the best pitchers in MLB during that span, and everybody knew it. Those were the good old days in Los Angels Dodger baseball lore.
Currently, Koufax serves as a member of the advisory board of the
Baseball Assistance Team, a non-profit organization dedicated to helping former Major League, Minor League, and Negro League players through financial and medical difficulties. On January 23, 2013 the Dodgers hired Koufax as a Special Advisor to team Chairman
Mark Walter. Koufax worked with the pitchers during spring training and will consult during the season.
[88] On April 1, 2013, Koufax threw out the first pitch during ceremonies at Dodger Stadium.
On July 14, 2015, before the
2015 MLB All-Star Game, Koufax was introduced as one of the four best living players (as selected by the fans of major league baseball), along with
Willie Mays,
Hank Aaron and
Johnny Bench. He threw the ceremonial first pitch to Bench from in front of the base of the mound.
I tried to keep this short. There's a lot more I could have included.
