Edward Augustine "Ed" Walsh (May 14, 1881 – May 26, 1959) was a Major League Baseballpitcher. From 1906 to 1912, he had several dominant seasons where he was one of the best pitchers in baseball. Injuries shortened his career. Walsh holds the record for lowest career earned run average, 1.82. He was inducted into the Baseball Hall of Fame in 1946.
Walsh made his major league debut in 1904 with the Chicago White Sox and pitched his first full season in 1906, going 17–13 with a 1.88 ERA and 171 strikeouts. In Game Three of that year's World Series, which the White Sox won over the Chicago Cubs in six games, Walsh struck out a then-World Series record 12 batters. He also struck out at least one batter each inning of that game; this feat has since been duplicated only once, by Bob Gibson in the 1968 World Series opener. From this season through 1912, Walsh averaged 24 victories, 220 strikeouts and posted an ERA below 2.00 five times. He also led the league in saves five times in this span. His finest individual season came in 1908 when he went 40–15 with 269 strikeouts, 6 saves and a 1.42 ERA. In 1910, he posted the lowest ERA (1.27) for a pitcher with at least 20 starts and a losing record. Walsh also set an American League record by pitching 464 innings in a season. On August 27, 1911, Walsh no-hit the Boston Red Sox 5-0.
Interviewed for Lawrence Ritter's book The Glory of Their Times, Hall-of-Famer Sam Crawford referred to Walsh's use of a pitch that was later outlawed: "Big Ed Walsh. Great big, strong, good-looking fellow. He threw a spitball. I think that ball disintegrated on the way to the plate, and the catcher put it back together again. I swear, when it went past the plate, it was just the spit went by".
In 1910, the White Sox opened White Sox Park, which was soon nicknamed Comiskey Park by the press in honor of team owner Charles Comiskey. The name was officially changed to Comiskey Park in 1913. An apocryphal story goes that architect Zachary Taylor Davis consulted Walsh in setting the park's field dimensions. Choosing a design that favored himself and other White Sox pitchers, rather than hitters, Walsh made Comiskey Park a "pitcher's park" for its entire 80-year history.
Walsh was a workhorse who pitched an average of 375 innings annually during the six seasons of 1907 through 1912. After the 1912 season, Walsh reportedly requested a full year off to rest his arm. Nevertheless, he showed up for spring training the following season, contending, "The White Sox needed me—implored me to return—so I did". As baseball historian William C. Kashatus observed, "It was a mistake".
Walsh's playing time began dwindling in 1913. It has been claimed that he came into spring training in poorer physical shape than other members of the White Sox pitching staff, and his pride led him to try to keep up with the other pitchers in terms of pitch speed before getting into adequate shape, thereby causing damage to his pitching arm. "I could feel the muscles grind and wrench during the game, and it seemed to me my arm would leap out of my socket when I shot the ball across the plate", Walsh later recalled. "My arm would keep me awake till morning with a pain I had never known before". He pitched only 16 games during the 1913 season, and a meager 13 games over the next three years.
By 1916 Walsh's arm was dead. He wanted a year off, but Charles Comiskey released him instead. He attempted a comeback with the Boston Braves in 1917, but was let go, ending his major league career. He later did some pitching in the Eastern League and gave umpiring a try, after which he was a coach for the White Sox for a few years.
Walsh retired with 195 wins, 126 losses and 1736 strikeouts. His career 1.82 is the lowest major league ERA ever posted, but is unofficial since ERA was not an official statistic in the American League prior to 1913. Though he has the second lowest career WHIP in MLB history (about 1.00), it is the lowest ever for a major league pitcher with 10 or more seasons pitched.
