Cueto will throw a bullpen Wednesday, after which the Giants will decide whether to insert him back into the rotation, Henry Schulman of the San Francisco Chronicle reports.
Cueto got hammered in his last rehab start, as he served up eight runs (five earned) on nine hits over three innings against High-A Stockton. He believes he is ready to return, but that poor outing has the Giants doubting him. If Cueto's arm doesn't look right Wednesday, the Giants could choose to shut him down for the rest of the season.
