What is better when using an IEnumerable with one item: yield return or return []?

This is one of those "you can do it many ways" questions. Consider the following code:

protected virtual IEnumerable<ScriptReference> GetScriptReferences()
{
    ScriptReference referece = new ScriptReference();
    referece.Assembly = "FeyenoordEnabled";
    referece.Name = "FeyenoordEnabled.PassTextBox.js";

    return new ScriptReference[] { referece }; 
}

protected virtual IEnumerable<ScriptReference> GetScriptReferences()
{
    ScriptReference referece = new ScriptReference();
    referece.Assembly = "FeyenoordEnabled";
    referece.Name = "FeyenoordEnabled.PassTextBox.js";

    yield return referece;
}

I only need to return one item. The first piece of codes returns an array with a single item and the second one yields the item. What is better and why?
