Hideki Matsuyama is not letting his end-of-year trophy extravaganza turn into a distraction, he said Monday, with his poor run of mid-season form ensuring he stays grounded ahead of next season.

"I wrapped up in a good fashion, but there was a long period in the middle (of the year) where I wasn't able to play the way I wanted," Matsuyama said at a sponsor event. "I still wonder if I could have done more."

The world No. 6 started the year on a high, winning the Phoenix Open in February for his second PGA tour title, before entering a barren run from June to August that saw him fail to make the cut in four of seven tournaments — including the U.S. Open and the Open Championship.
