Conforto (hamstring) will begin a rehab assignment with Triple-A Sacramento on Friday, Alex Pavlovic of NBC Sports Bay Area reports.
Conforto continues to work his way back from a right hamstring strain that he sustained May 11 against the Reds. Before landing on the IL, Conforto was slashing .280/.331/.490 with seven home runs and 20 RBI over 154 plate appearances. He may only need a few rehab appearances before being activated.
