The Yankees optioned Hanner to the rookie-level Florida Complex League following Thursday's 6-4 victory over the Rays.
Hanner earned his first major-league win Thursday, allowing two hits without a walk or a strikeout over two scoreless innings. However, he still has an 8.59 ERA with the big club, and the Yankees need a fresh arm or two after Saturday's game against Baltimore was rescheduled as part of a day-night doubleheader Friday.
