"He threw three innings of a simulated game and did some pitchers' fielding practice. He still doesn't look confident enough running around and moving around to send him out there to compete in a game," Acta said.
"He's still not confident enough on his ankle to react to balls and to run. So, he's still not 100 percent on that."
Hernandez has played just three games this season, and none since Aug. 27 against the A's, when he left after 2 1/3 innings with a sprained right ankle. He threw a bullpen session on Tuesday that didn't reveal any problems, but Friday's simulated game was a different story.
"We're going to have another simulated game in Chicago [on] Wednesday for him, and then we'll make a decision after that one," Acta said. "The whole thing behind the Roberto issue is to have him healthy by Oct. 3. So whether it's going to be two simulated games or pitching on the field, that's going to be dictated after the next one."
Acta said that Hernandez would pitch in winter ball this offseason, as he usually does. However, with just 14 1/3 innings of work this season, Hernandez is hoping the Indians will give him permission to pitch more in winter ball, according to Acta.
After missing the first four months of the season dealing with legal issues, Hernandez -- formerly known as Fausto Carmona -- was activated from the restricted list on Aug. 14. In three starts, he allowed 15 runs (12 earned) on 17 hits, including four home runs. He lost all three games and posted an ERA of 7.53.
