Henri Joseph Rondeau (May 5, 1887 – May 28, 1943) was an American baseball player. He played professional baseball as an outfielder and a catcher for 17 years from 1909 to 1925, including parts of three seasons in Major League Baseball for the Detroit Tigers in 1913 and the Washington Senators from 1915 to 1916. He also played in all or parts of 12 seasons with the Minneapolis Millers in the American Association. Early years Rondeau was born in Danielson, Connecticut, in 1887. He played baseball as a boy in Danielson and began playing organized baseball as a second baseman for the Perseverance team out of Woonsocket, Rhode Island, in the Mill League. Professional baseball Minor leagues In 1909, while playing for the Perseverance team, Rondeau was discovered by Jesse Burkett and signed to play with his Worcester Busters team in the New England League. He played for Worcester, principally as a first baseman but also as an outfielder, in 1909 and 1910. Late in the 1910 season, after injuries to the Worcester catchers, Burkett moved Rondeau to that position. In 1911, he was sold to the Providence Grays in the Eastern League. After the 1911 season, he was traded to the Jersey City Skeeters of the International League. He compiled a .311 batting average in 90 games for the Skeeters. Detroit Tigers On September 16, 1912, Rondeau was drafted by the Washington Senators in the Rule 5 draft, but the Senators then sold him to the Detroit Tigers two days later for $4,000. After watching him earn the backup catcher position during spring training, E. A. Batchelor of the Detroit Free Press described Rondeau as a "scrappy" player who regularly engaged in heated dialogue with umpires over ball and strike calls – a fighting spirit that Batchelor concluded would make Rondeau valuable to the Tigers. Rondeau appeared in 36 games for the 1913 Detroit Tigers, including 12 games as the team's starting catcher and four games as the starting first baseman. He compiled a .186 batting average with the Tigers. In August 1913, he suffered sun stroke and was hospitalized for several days. Minneapolis After his release from the hospital, he was traded by the Tigers to the Minneapolis Millers of the American Association. He hit .378 for Minneapolis in 19 games at the end of the 1913 season and continued to play well for Minneapolis in 1914, appearing
