Atlanta Braves third baseman Austin Riley was placed on the 10-day injured list for the second time in two months with a strained lower abdominal muscle on Monday.
Riley suffered the injury while tagging out Cincinnati's Elly De La Cruz near home plate in the Braves' 4-2 win on Sunday in the rain-delayed MLB Speedway Classic at Bristol Motor Speedway.
Riley also landed on the IL on July 12 with a strained abdomen. He returned on July 25.
