Willett, who rallied from five shots down to capture the 2016 Masters, fell to No. 462 in the world rankings two years later. There is no guarantee that players who go through a slump of such magnitude come close to regaining their old form.

Yet Willett, 32, of England, has done just that, climbing to No. 30. In September, he captured the BMW PGA Championship to record his second European Tour victory in 10 months and his seventh over all.

He took a few big steps back recently at the CJ Cup at Nine Bridges in South Korea, finishing in a tie for 46th , and at the WGC-HSBC Champions event in China , where he was unable to break 76 in his last three rounds . Still, it would not be a big surprise if Willett were to rebound in Turkey. He tied for fourth on this course in 2014, and tied for 11th in 2015.

“I’m back to, not where we want to get to, but we’re now back to a place where we feel we should be a little bit more comfortable,” Willett said.
