Hughes, who has been on the disabled list with a dead arm since April 15, said he felt fine and will throw again Wednesday and have Thursday off. He will travel with the Yankees to Seattle, where they begin a three-game series Friday.
The right-hander said Tuesday's session was more intense than others, but he still does not have a timetable for throwing off a mound.
"I don't know what it is," Hughes said of the throwing program. "I could walk in [Wednesday] and they say, 'You're getting on the mound.' I just don't know, so [I'm] trying not to get caught up in the scheduling of everything."
