Atlanta Braves third baseman Austin Riley was on Monday placed on the 10-day injured list for the second time in two months with a strained lower abdominal muscle.
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.
The Braves recalled infielders Nacho Alvarez Jr. and Jonathan Ornelas from Triple-A Gwinnett before opening a home series against Milwaukee on Monday night. The team optioned outfielder Jarred Kelenic to Gwinnett following Sunday's game.
Riley is hitting .260 with 16 homers and 54 RBIs.
