Acting manager Mark Parent said closer Addison Reed is definitely not seeing any action after throwing 55 pitches a day earlier. Jessie Crain will handle the closer duties if necessary.
Parent took over from Robin Ventura, who will be in California for the next two days attending the high school graduation of his daughter.
White Sox starter Jose Quintana will need to be at his best Thursday to take the load off the bullpen.
"Our pitchers have been dealing with a lot of pressure anyway," Parent said, referring to the struggling offense. "Sometimes we feel we can give up only one run and still have a chance, maybe two. Hopefully our offense picks that up and our pitchers can relax a bit. It's like every game we got. One-run game here and there. They're used to doing that. It shouldn't be anything different."
After arriving in Chicago around 1 a.m. early Thursday morning, players weren't required to report to U.S. Cellular Field until 4:30 p.m. in advance of the 7:10 p.m. start against the Athletics. The White Sox also skipped batting practice.
It was impossible, though, to steer the conversation from anything but the 7-5 victory over the Seattle Mariners that was scoreless after 13 innings and then saw both teams score five runs in the 14th. The White Sox finally won it in the 16th.
"I've played a million games over my career probably like everyone in here, and that game was probably one of the most awkward, weird games," captain Paul Konerko said. "The whole game, leading into the game (on an eight-game losing streak), the clubhouse after, it was all just very bizarre. You think you've seen it all. We won. That was nice. That's a game you won't forgot. That's up there in the top 10 I'll always remember."
As far as coping with tired bodies and sleep deprivation, the White Sox will just have to fight through the exhaustion.
"With the time change, the sleep gets messed up," Konerko said. "For me you're always kind of aching and sore anyway. It's just normal. I think it brings other guys into it. For (Gordon Beckham) he can know what it's going to feel like 10 years from now. He'll get a little insight. It will go away but it brings more people to that level."
Konerko hopes the exhaustion has a delayed effect.
"It's not always the (first night) it's the next day," he said. "I think the main thing is your diet, hydrate and stuff because you do bounce back the next day and then it hits you after that. But you can be conscious of that and stop that from happening if you're smart."
