TUESDAY, 10:22am: Young has been granted his release, according to a tweet from the Nationals.
Mark Zuckerman of CSN Washington adds (also via Twitter) that the Nationals will still have 24 hours to add Young to the roster before the paperwork is officially filed. It is Young's preference to stay with the Nationals, according to Adam Kilgore of the Washington Post (Twitter link). That seems unlikely, as the Nats recently told Young that he wouldn't make the 25-man roster, but he would be their primary choice should a member of their rotation be injured.
Scouts from several teams were on hand today to watch Young's final Spring Training start for the Nationals, during which he allowed just an unearned run on two hits and a walk with two strikeouts through four innings.
Young signed a a minor league deal with the Nationals in late February after a season in which he posted a 4.15 ERA, 6.3 K/9 and 2.8 BB/9 in 115 innings for the Mets.
