The Yankees signed Hanner to a major-league contract and optioned him to Triple-A Scranton/Wilkes-Barre on Saturday.
After exercising an opt-out with the club Monday, Hanner is back with the Yankees, joining the 40-man roster and making his way back down to Triple-A. With Scranton/Wilkes-Barre this season, the 27-year-old has posted a 1.99 ERA, 1.16 WHIP and 50:16 K:BB through 40.2 innings. To make room for Hanner on the 40-man roster, the Yankees transferred Aaron Judge (ribs) to the 60-day injured list.
