Moving Paredes to the IL wasn't the only move the Astros made Sunday. The team also optioned catcher Cesar Salazar to triple-A Sugar Land. That opened two roster spots, and the Astros filled them by recalling infielder Shay Whitcomb and calling up veteran and recent re-signee Jon Singleton.

Injuries keep mounting for the Astros. The latest is slugger Isaac Paredes, who suffered a hamstring injury Saturday night.

The Houston Astros have been faced with a series of bad news announcements that leave them barely clinging to the AL West lead.

After Isaac Paredes was named as a replacement for Jose Ramirez, he is backing out of the Midsummer Classic due to personal reasons.
