D'Arnaud was claimed off waivers by the Red Sox on Thursday, Brian MacPherson of the Providence Journal reports.
D'Arnaud will take the roster spot of Carson Smith, who was moved to the 60-day DL to make room for the 30-year-old. With Pablo Sandoval (knee) and Brock Holt (vertigo) on the DL and Dustin Pedroia still hobbled, it isn't too surprising to see Boston scoop up the super-utility man. D'Arnaud was batting .375 in eight at-bats (11 games) with the Braves before being DFA'd Tuesday. He should offer infield depth for the Red Sox when he is activated.
