William Anthony "Wild Bill" Hallahan (August 4, 1902 - July 8, 1981) was an American lefthanded pitcher in Major League Baseball during the 1920s and 1930s. So named because of his lack of control on the mound — he twice led the National League in bases on balls — Hallahan nevertheless was one of the pitching stars of the 1931 World Series and pitched his finest in postseason competition.
He also was the starting pitcher for the NL in the first All-Star Game in 1933, losing a 4-2 decision to Lefty Gomez of the American League and surrendering a third-inning home run to Babe Ruth in the process.
Hallahan, a native of Binghamton, New York, spent most of his career in the employ of the St. Louis Cardinals. He signed with their nearby AA farm club, the Syracuse Stars of the International League, in 1924. The following season, he made his first NL appearance for the Redbirds, appearing in six games. In 1926, Hallahan pitched in 19 games for the Cardinals during the regular season, and made a first, brief World Series appearance that fall against the New York Yankees.
But Hallahan was not yet ready for an extended major league career. He spent 1927 with Syracuse, winning 19 games and leading the International League in strikeouts (195) and walks (135). The next season, he won 23 games for the Houston Buffaloes and led the Texas League in strikouts (244). Finally, in 1929, he rejoined the Cardinals.
He became a starting pitcher in 1930, winning 15 games for the pennant-winning Cardinals and leading the NL in strikeouts (177) and walks (126). In the 1930 World Series against the Philadelphia Athletics, Hallahan split two decisions but he shut out the powerful A's in Game 3 and allowed only two earned runs in 11 innings, for a sparking ERA of 1.64. Philadelphia won the Series in six games, the only World Series Hallahan's Cardinals would ever lose.
In 1931, Hallahan again led the NL in strikeouts (159) and walks (112) and won 19 games, as St. Louis again took the league championship for a rematch against the Athletics. This time, Hallahan was even more effective. He shut out the A's again in Game 2, pitched a complete game 5-1 victory in Game 5, and nailed down the decisive Game 7 in relief by getting the last out in the ninth inning. Altogether, he gave up only 12 hits and one run in 18⅓ innings — an ERA of 0.36 — as St. Louis triumphed in seven games. Hallahan's dominance is even more impressive because the A's featured a predominantly righthanded-hitting lineup, including fearsome sluggers Jimmie Foxx and Al Simmons.
After two more winning campaigns for non-contending Cardinal clubs, Hallahan won only eight games, losing 12, for the 1934 edition. But the Gashouse Gang won the National League title and gave Hallahan one more chance to experience the big stage. In Game 2 of the 1934 World Series, against the Detroit Tigers, Hallahan started against Detroit ace Schoolboy Rowe and left with one out in the eighth inning of a 2-2 tie. Detroit won the game in the ninth, 3-2, but overall the Cardinals again prevailed in seven games.
Altogether, in seven World Series games and 39⅓ innings, Hallahan won three games, lost one and compiled a sparkling ERA of 1.51.
He stayed with the Cardinals until May 31, 1936, when he was sold to the Cincinnati Reds, then a second-division team. His career statistics suffered with the Reds and his final club, the cellar-dwelling Philadelphia Phillies. Over his last two seasons, 1937-38, Hallahan won four and lost 17 games.
He finished with a regular-season record of 102 victories and 94 defeats, 856 strikouts and 779 walks, and an ERA of 4.03 in 1,740 innings pitched.
After retiring from baseball, Hallahan worked as a supervisor for General Aniline and Film Co. in Johnson City, New York. He died at age 78 in Binghamton.
