D'Arnaud has been out all season after undergoing surgery in March to repair a partially torn ligament in his thumb. The Pirates are expected to send him to the minors when he's healthy enough to return.
Yankees claimed LHP David Huff off waivers from the Indians.
Huff was designated for assignment by the Indians last week after he posted a 4.07 ERA, 1.23 WHIP and 28/9 K/BB ratio in 24 1/3 innings at the Triple-A level. The Yankees waived left-hander Francisco Rondon in a corresponding move.
