Naeim under O’Shea finished about four lengths ahead of Amadeusz BS under Richard Mullen with MH Lazzaz running into third place.
It was a third career success for Naiem, all at Al Ain, but first at this trip having scored both previous victories over 1400m, most recently in a handicap at the end of January.
His only previous attempt at 1600m had resulted in a heavy defeat on the Abu Dhabi turf, in November 2015, but he appeared to relish it here and had this race won from a long way out.
“He has stayed very strongly and done that nicely,” said O’Shea. “The yard always has their horses in good shape and it is a great start to the day.”
