The Oakland A's are expected to call up top prospect Daniel Mengden to start on Saturday in Cincinnati against the Reds. The news was first reported by Jane Lee of MLB.com, who notes that the team has not officially commented on the move. Mengden was acquired from the Astros last July in the deadline deal for Scott Kazmir.
Mengden entered the year as the No. 15 prospect in Oakland's system according to our Community Prospect List, but his performance this season has shattered that ranking along with any conceivable expectations anyone may have ever had for him.
