Swarzak also simulated coming off the mound to field a ground ball to make sure his ankle was fine, and he reported everything went well and that he won't need a trip to the 15-day disabled list.
"The ankle is doing good," Swarzak said before Saturday's game against the Royals. "Yesterday, I took a really good step forward and feel pretty good today. So no need for the DL. I ran around and threw and everything is OK."
