"He'll have limited activity and stay inside [during pregame work]," Wedge said. "He still feels it a little bit."
Any concern over his next start?
"I don't think there's any concern for that right now," Wedge said. "Hopefully he feels better at the end of the day today and coming in tomorrow."
Hernandez "tweaked" his back in the second or third inning of Friday's 7-4 loss to the White Sox. Wedge pulled him after the fifth inning, trailing 4-0, though Hernandez wound up with a no decision when Seattle tied the game back up in the eighth.
Trainer Rick Griffin checked on Hernandez throughout the game and felt there was no problem in letting him continue, but Wedge pulled the right-hander when his pitches started getting up in the fifth and the White Sox hit back-to-back home runs.
Hernandez said the back wasn't the problem after the game, but that his fastball command again was an issue. He's 1-3 with a 6.14 ERA in his last five starts.
"I love that he feels that way," Wedge said. "We want all our players to take full accountability, but reality is sometimes there are physical issues involved, and I think that is the case with Felix. I know there have been times this year when he's unhappy with himself, but that's part of being a great pitcher and self-evaluator, too.
"You're not always going to be perfect, and you're not always going to be great. But you have to recognize when you're not so you can get back to that level and I think he does that as well as anybody."
