The Angels placed Rendon on the 10-day injured list Tuesday, retroactive to Sunday, due to a left oblique strain.
Manager Ron Washington said Monday that Rendon was expected to rejoin the lineup Tuesday after sitting out two straight games due to back soreness, but the third baseman will instead move to the injured list after being diagnosed with an oblique injury. The 34-year-old will be eligible to be reinstated Sept. 18, but there's no guarantee he's back before the end of the campaign, especially given his injury history.
