Semien is experiencing left side soreness and is undergoing an MRI, Alex Coffey of The Athletic reports.

EDGE Analysis

The 30-year-old was a late scratch for Game 2 of Saturday's doubleheader, and the MRI brings some concern he could face a longer absence. The A's should have more information on the injury Sunday, but Semien at least seems unlikely to be in the lineup for the series finale in Houston.
