"They haven't decided, and I'm a possibility," said Axelrod, who was recalled from Double-A Birmingham prior to Tuesday's contest. "We'll see. They need to talk and see how it goes."
"Nobody knows," Santiago said. "They said, 'Get ready, and if it happens, it happens.' But we aren't thinking that far ahead. We are focused on this game against the Twins."
Santiago earned the victory Monday by allowing one run over five-plus innings in his first Major League start. Axelrod picked up the White Sox lone victory on their recently completed seven game road trip, yielding one run on three hits over 7 1/3 innings against Baltimore on Wednesday, and pitched 2 2/3 innings in relief of Jose Quintana during Tuesday's 18-9 loss.
That previous starting experience helps put these rookies at ease when pitching in playoff-type situations.
"I'm just excited more than anything. This is going to be a lot of fun down the stretch," Axelrod said. "I just hope I can contribute as much as I can. If it's out of the 'pen, that's fine. If it's a spot start here or there, that's fine, too."
