Citing baseball technicalities, Yankees general manager Brian Cashman said Friday that pitching prospect Dellin Betances will move to the bullpen, the New York Post reports. Betances runs out of minor-league options after this season and will be required to make the 25-man roster next year or be subjected to waivers.

"This is the problem with the development clock," Cashman said. "If he had two or three more options, we would keep working with him as a starter. But with him being out of options after this year, it is becoming more obvious that if he is going to help us, it is going to be out of the pen."

The 6-foot-8 Betances has displayed improvement with Triple-A Scranton-Wilkes/Barre recently to even his record at 2-2 and lower his ERA to 6.00. The right-hander threw five no-hit innings during his last start Sunday but has walked 16 in 24 innings this season.
