George William Pipgras (December 20, 1899 – October 19, 1986) was an American right-handed starting pitcher and umpire in Major League Baseball. Known as "The Danish Viking," he spent most of his playing career with the New York Yankees, breaking in as a rookie in 1923. He spent the 1925 & 1926 seasons in the minor leagues, and became a starter in the rotation for the first time with the legendary 1927 team. Pipgras lead the American League in wins with a 24–13, 3.38 ERA record for the following year's 1928 repeat champions. After ending his 11-year career with the Boston Red Sox, he became an AL umpire from 1938 to 1946. He was the umpire behind the plate in one of baseball's most dramatic wins ever: on September 30, 1945, at St. Louis' Sportsman's Park, when Hank Greenberg hit a ninth inning Grand Slam, after Pipgras suggested to Greenberg that the game should be called on account of darkness. Greenberg convinced him the he could still see the ball, so the game proceeded. The next pitch was hit over the fence and the Tigers won the pennant, and eventually the 1945 World Series. His younger brother Ed pitched briefly for the 1932 Brooklyn Dodgers.
Pipgras was born in Ida Grove, Iowa, and served in World War I with the 25th Army Engineers. He started his major league career with the Yankees in the 1923 season after being acquired from the Red Sox, making 17 appearances in his first two years. After returning to the minor leagues for two more years, he earned a place in the starting rotation in 1927, posting a 10–3 record for the team still considered by many to be the greatest ever, and winning Game 2 of the 1927 World Series against the Pittsburgh Pirates. In 1928 he led AL pitchers in wins with a 24–13 record, and also in games started (38) and innings pitched (300-2/3), while finishing second in strikeouts (139); he followed up with another Game 2 victory in the 1928 World Series against the St. Louis Cardinals as New York swept the NL champions for the second straight year. He was 18–12 as the Yankees slipped to second place in 1929, and 15–15 in 1930 with an AL-leading 3 shutouts. After a 7–6 season in 1931, he bounced back with a 16–7 mark for the 1932 AL champions, and again won his World Series start in Game 3 as the Yankees swept the Chicago Cubs. In that game, Babe Ruth and Lou Gehrig each hit a pair of home runs, including Ruth's renowned "Called Shot." In May 1933, Pipgras' contract was sold back to the Red Sox, and he was 9–8 for the team that year before making a handful of appearances in 1934 and 1935. In an eleven-season career, he posted a 102–73 record with 714 strikeouts and a 4.09 earned run average in 1488-1/3 innings.
