Ray (hamstring) is expected to throw a three-inning simulated game Saturday, MLB.com reports.
Ray already tossed a two-inning sim game Wednesday, so he'll be looking to get stretched out a bit more Saturday. The Giants placed Ray on the 15-day injured list Aug. 27 with a left hamstring strain, but provided he experiences no setbacks while building up, the southpaw should be able to return to the big club in a starting role down the stretch. The club hasn't indicated whether Ray will need to make a minor-league rehab start prior to being activated, but he'll likely require at least another sim game after Saturday before he's ready to handle a starter's workload for the Giants.
