No one appears to be safe on the St. Louis Cardinals roster right now, and it sounds like Sonny Gray has at least thrown his name into the mix as someone who could be moved over the coming days.
In a report this morning from Katie Woo of The Athletic, the Cardinals are now "entertaining offers" on both Gray and Nolan Arenado, with president of baseball operations, John Mozeliak, calling rival contenders to gauge their interest in acquiring him. Earlier this week, Mozeliak said he would approach players with no-trade clauses on their roster about if they are open to being traded, so I doubt he'd be gauging the interest of teams on Gray if he was not open to being moved.
