TRENTON -- The Thunder today placed Dellin Betances on the 7-day disabled list with what Yankees VP of Player Development Mark Newman says is a blister. He said he expects Betances to miss "a start."

In his place the Thunder received Brian Anderson from Staten Island. Anderson, a former outfielder with the White Sox, is trying his hand as a pitcher.

Betances, in his lone start of the year, in New Hampshire, allowed one earned run over four innings and took the loss. The disabled list move is retroactive to April 11.
