It was an unusual setting for baseball. Instead of a blue sky, there was the darkness of space and the brilliance of stars overhead. The light of Earth flooded the scene, and surrounding the oversized diamond were the walls of Copernicus crater, over fifty miles across.

On the mound, Bill Cherry was pitching practice balls to his catcher, Ollie Taylor. Only underhand throwing was allowed in baseball on the Moon, for the ball was exceedingly fast in the light gravity and airlessness. Bill, in snug-fitting space gear, was standing farther than the regulation ninety feet from the plate. This was because of the pitcher’s advantage over the batter in Lunar ball.

Bill wound up and threw. The ball shot like a bullet into Ollie’s double-padded mitt.

“Thatta boy, Bill!” Ollie’s voice came over Bill’s space suit radio. “If you’re this sharp when we meet the Comets this afternoon, we’re bound to win our first championship!”

“That’s enough practice, fellows!” Coach Lippert called, coming out of the dugout. “No use giving our best before the game!”

It was the big game for the team from Plato, which was tied with the league leaders in this last game of the season. Plato was the farthest colony on the Moon and was named for the big crater in which it was located. Copernicus colony, the baseball leader, had won the championship every year since the school league had been formed. As a prize, the champions were always given a free rocket trip to Earth.

The Plato Rocketeers were homesick for their mother planet. One of them, little Pete Irby, had never set foot there. He had been born on the Moon.

“It must be wonderful to go around without even a space suit on like they do on Earth!” Pete said wistfully to Bill.

“Don’t worry, Pete,” Bill said confidently. “I have a feeling that this is our year and that we’re all going to Earth.”

“I sure hope you’re right,” Pete replied, with great feeling. “I can’t wait to see the great national parks and rivers and all the other wonderful things there!”
