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. Later career 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". 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 (he umpired 87 American League games during the 1922 season), after which he was a coach for the White Sox for several seasons (1923–1924,
