 Through three AAA starts, Ashcraft's ERA sits at a sterling 0.59, which is one earned run in 15 and a third innings. On Thursday, Quinn Priester opened his rehab assignment, tossing four innings of two-run ball, striking out one, not walking anyone. Priester got up to 57 pitches, and he'd be slated to make his next start tomorrow night in Louisville if he's working on four days rest.
