O'Brien was claimed off waivers by the Dodgers on Sunday, Ken Gurnick of MLB.com reports.
EDGE Analysis
O'Brien was designated for assignment by the Rangers on Saturday after getting off to a very sluggish start within their minor-league system this season. The Dodgers will immediately assign O'Brien to Triple-A Oklahoma City where he'll serve as organizational outfield depth moving forward. Jason Wheeler was DFA'd to open up the roster spot.
