Once in a while her brother Hank and his friends would let her play first base in their games. More often, however, they asked her to umpire (裁判) for them, because they knew her calls would be fair and there would be no arguing.One day in 1904, Amanda and her mother traveled to Hawarden, Iowa, to watch Hank play for the home team against Hawarden. When they arrived at the ball field, two local teams were waiting to play a preliminary (预备) game. The umpire hadn’t arrived, so Hank argued that the teams should let his sister serve as umpire. The players finally agreed.Amanda, then sixteen and standing five feet, ten inches tall, made perfect calls.
