Braves' William Contreras: Joins Atlanta for twin bill

Atlanta called up Contreras from its alternate site to serve as the 27th man for Sunday's doubleheader versus Arizona.

He'll be the No. 3 catcher behind Travis d'Arnaud and Alex Jackson for the twin bill, though he won't be guaranteed to pick up a start in either contest. The 23-year-old backstop is expected to head back to the alternate site after the doubleheader in preparation for joining Triple-A Gwinnett for the start of its season next week.
