Manager Bruce Bochy, who at times stood in the batter's box during Cueto's session, echoed the right-hander's remarks.
"That session went fine," Bochy said, adding that Cueto would not be limited by a pitch count.
The first-year Giant's improved health is certainly great news for San Francisco, which entered its final homestand of the season just a game ahead of the Cardinals for the second National League Wild Card spot.
Cueto is 17-5 with a 2.79 ERA in 31 starts this season. He has been dominant in September, too, posting a 1.59 ERA in four starts before sustaining the groin injury Sept. 20.
