It was on the Canadian hardcourts where Halep took down Angelique Kerber and while the German did gain revenge in Cincinnati recently, there is no doubt Halep has restored her confidence ahead of the action at Flushing Meadows where last year she made the semis.
The baseliner, who has regularly changed coaches in recent years, is now with highly-respected Australian Darren Cahill, who previously worked with Lleyton Hewitt and Andre Agassi.
The signs are that he is making a difference and could be the trigger for a maiden Grand Slam title, although for that to happen Halep will need to ditch a reputation for faltering in matches of the highest importance.
