Cover rules and spells that move as bonus action

The rules of cover are as follow:

A target with half cover has a +2 bonus to AC and Dexterity saving throws

Let’s say a wizard casts flaming sphere. He can then move the sphere as a bonus action to ram it into an opponent. If there is a cover in between the wizard and its target, but there are no obstacle between the sphere and the target, does the target benefits from the +2 bonus to the Dexterity Saving Throw ?
