Stanek was recalled by the Rays on Saturday, Marc Topkin of the Tampa Bay Times reports.
Stanek's promotion comes after the Rays sent starter Blake Snell down to Triple-A Durham. Stanek has had an excellent start to his season with Durham, notching a 2.00 ERA with 25 strikeouts and six walks in 18 innings. He'll work out of the bullpen when he joins the Rays.
