Hughes allowed one run on three hits in the outing at New Britain, walking two and striking out three. His velocity was reported to hover between 91 and 93 mph.
The rehab start was Hughes' second as he makes his way back to New York's rotation, having gone on the disabled list in April due to inflammation in his pitching shoulder. He appeared last Sunday for Class A Staten Island at Brooklyn, allowing one earned run in 4 1/3 innings in a 61-pitch outing.
It is expected that Hughes will need one more Minor League start, somewhere in the neighborhood of 90 pitches, before the Yankees would consider activating him.
"Our plans are to have him continue to progress," Yankees manager Joe Girardi said before Friday's game. "When we feel that he's ready, he'll be back. He's looked very good in the starts that he's made, and we want that to continue."
