Carson Park and Hank Aaron

Tucked into Half Moon Lake on a wooded peninsula in Eau Claire is a stadium that would be easy to miss, but it holds a specific and important place in the history of American baseball. This is Carson Park, and on June fourteenth, nineteen fifty-two, an eighteen-year-old named Henry Aaron stepped onto its field for his first professional at-bat.

Hank Aaron had come to Eau Claire from Mobile, Alabama, by way of the Indianapolis Clowns of the Negro Leagues, where he had been discovered playing shortstop. The Milwaukee Braves organization signed him and assigned him to the Eau Claire Bears of the Class C Northern League. It was his first time playing on an integrated professional team, and his first time living in a northern city.

What followed that summer was a preview of everything to come. Aaron hit for a three-thirty-six average in eighty-seven games, made the Northern League All-Star Team, and was named the league's rookie of the year. His strike-out rate was famously low. Teammates and coaches recalled that he hit with a peculiar closed stance and exceptional wrist speed, turning on inside pitches with a snap that no one could quite teach or explain.

The Bears played in Carson Park stadium, completed in nineteen thirty-seven with Works Progress Administration labor and state-of-the-art lighting for night games. The stadium was placed on the National Register of Historic Places in two thousand three, in part because of that single season. In nineteen ninety-four, Eau Claire installed a bronze statue of Aaron at the park, and Aaron himself came to the dedication.

Twenty-two years after his summer in Eau Claire, on April eighth, nineteen seventy-four, Aaron hit his seven hundred and fifteenth home run in Atlanta, breaking Babe Ruth's career record. It started here, on a WPA diamond in a Wisconsin river town.
