She won in Madrid and despite being hampered by an ankle injury then finished runner-up in both Rome and Paris.
But that final loss at Roland Garros to Jelena Ostapenko was another example of her failing to deliver on the biggest stage. The mental side of her game has long been a weakness - she led that final as the favourite by a set and 3-0.
As a result, Halep remains without a Grand Slam title and it seems unlikely to arrive at Wimbledon given her tournament history.
Her best effort came three years ago when she made the semis but she also has four exits before the third-round stage on her record.
With disappointment to overcome, coach Darren Cahill, who has worked with Andre Agassi and Lleyton Hewitt in the men's game, may well have a big part to play if Halep is to challenge at the business end of the fortnight.
