The Nationals have made clear they'd like to re-sign last year's ace Jordan Zimmermann, who has said he'll sign if given a fair deal.
Also, more on interest in Ross Detwiler and the Nationals may trade a reliever before a starter.
The Astros have asked about Clippard; the Angels and Rangers were interested in Ross Detwiler; and other notes.
The right-handed starter's representatives and the Nationals are set to meet this week at the Winter Meetings.
The Nationals don't have a need for a starter -- but two of them, Doug Fister and Jordan Zimmermann, are a year away from free agency.
"We're talking baseball and anything can happen," said the right-handed starter, who has one year left before free agency.
The Nationals could still benefit if they neither sign nor trade Jordan Zimmermann.
A report said the Cubs asked the Nationals about the right-handed starter with only one year left of control.
Matt Williams says Stephen Strasburg could pitch out of the bullpen in any role; Zimmermann would pitch on normal rest Thursday.
"I kicked myself all night," Williams said of his decision. "That's human nature."
