Hendriks has decided not to pitch for Team Australia in the World Baseball Classic, Ken Rosenthal of Fox Sports reports.
His decision to withdraw from the WBC does not appear to be injury-related, but instead just a personal decision not to go. The 28-year-old right-hander will now have the opportunity to spend the entirety of spring training with the Athletics, as he looks to get himself ready for another season in Oakland's bullpen.
