SHENZHEN, April 25, 2014 (AFP) - The 15-year-old amateur shot a disappointing 76 in the Volvo China Open second round on Friday to miss the cut by three shots, a far cry from his Masters exploits a year ago.
Last April at Augusta, Guan earned rave reviews when he became the youngest player to make the weekend in a major championship, aged just 14 years and five months.
He followed that by reaching the final rounds at his next PGA event, the Zurich Classic in New Orleans, but a missed cut at December's Hong Kong Open ended a breakthrough 2013 on a quiet note.
However the Guangzhou schoolboy is confident he's on the right path, and he will play fewer professional tournaments this year as he carefully plots his road to success.
"I think definitely I'm making the right progress," said Guan at the Genzon Golf Club in Shenzhen.
"Last year I had a great tournament (at the Masters) and lots of great experiences and this year I didn't want to play too many tournaments at first because it's still not the right time.
"Last year I played maybe 10 to 12. I played in a couple of really big ones so I got great experience from that," he added.
Guan appears comfortable in the spotlight and he was a star attraction at the 20th edition of China's national championship, a $3.2 million event co-sanctioned by the European Tour and OneAsia.
He opened with a solid one-under-par 71 on Thursday but struggled on the greens in round two, missing short putts for par at 18 and two and finishing with a four-over 76 to leave him at plus three.
"I'm a little bit disappointed, the swing just wasn't there," he said, adding that perhaps the lack of recent tournament practice was a factor.
But the great hope of Chinese golf is happy to bide his time, saying he has no immediate plans to turn professional and no target for when he'd like to break into the world's top ranks.
"I'm focusing back on my school and my body," the slight youngster said, referring to his attempts to bulk up so he can hit the ball further.
"I don't have any plans for a timetable yet. To keep playing in those high-level tournaments is wonderful so I don't start thinking about it yet."
- 'Chinese major champion' -
Guan has stopped using a long-handled putter, which will be banned from 2016, and says he feels "confident" with the conventional length.
China is yet to have a truly recognisable golfing superstar -- its highest players in the rankings currently are Liang Wenchong at 137 and Wu Ashun at 144.
But at the China Open, top players Henrik Stenson and Ian Poulter said it won't be long before that changes, with the world number three Swede singling out Guan for praise.
"When I first came here the local players were at the bottom of the results list, but over the past few years the local players' results are getting better and better," Stenson said.
"We had a 14-year-old Chinese player making the cut at last year's Masters. If you had put me out at Augusta at the age of 14 I think 90 would have been a good score for me. It is very impressive in a short period of time."
Poulter said: "There will be a Chinese major champion. I am not saying that will be in two years or five years or 10 years but it is happening."
Guan hopes he will eventually be that champion, but for this year he's focusing on playing for China at the Asian Games in South Korea in September.
"I really wish I can play with my home country," he enthused. I'm not sure if I'll be selected but I'm hopeful."
