Puig was available for pinch-hit duty on Friday, since the hamstring loosened up well during pregame batting practice.
That was enough for Dodgers trainer Stan Conte and manager Don Mattingly to declare Puig fit to play.
"Stan felt like he was fine after watching him yesterday, no reason to worry," Mattingly said. "Everything warmed up fine for [Friday's] game, so we're very confident that he's OK."
The Dodgers scored only two runs in 20 innings after Puig left in the eighth inning of Tuesday's 5-4 loss to the A's.
• Mattingly said he saw the pictures and videos alleging Fiers had pine tar in his glove during the game, but he didn't see anything out of the ordinary during the game and didn't want to take anything away from Fiers' feat a day later.
"I think it sounds like you're whining if you talk about it. ... I think a lot of guys use [pine tar]," he said. "I think it's kind of accepted in our game. ... I had no idea during the game, and nobody said anything to me about it, so obviously I didn't [notice it]."
