The 20-year-old Acuna singled and scored the tying run in the eighth inning of his big league debut, and the Atlanta Braves went on to beat the Cincinnati Reds 5-4 Wednesday night.
Acuna became the youngest player in the majors when he was called up from Triple-A before the game. He went 1 for 5 and played left field.
''As soon as I hit the field, I felt at home,'' Acuna said through a translator. ''I felt comfortable.''
Atlanta manager Brian Snitker saw no signs of nerves from his prodigy.
''I thought he was really good,'' Snitker said.
