Estrada (concussion) will likely rejoin the Giants ahead of Sunday's series finale in Oakland, Alex Pavlovic of NBC Sports Bay Area reports.
Estrada landed on the 7-day concussion injured list last weekend but is expected to be cleared to return following a minimal IL stint. The 26-year-old should reclaim a regular role at second base once activated since shortstop Brandon Crawford (knee) is expected to be reinstated Saturday.
