Rendon (back) was spotted fielding groundballs Sunday and is expected to be activated from the 10-day injured list when first eligible Tuesday, Jeff Fletcher of The Orange County Register reports.
The 34-year-old hasn't seen game action since July 26 due to lower-back inflammation, but he's poised to rejoin the active roster after spending the 10-day minimum on the IL. Rendon had been serving as the Angels' leadoff hitter prior to the injury, but he won't immediately reclaim that role once reinstated.
