Clubhouse leader at the Indonesian Open, Thanyakon Khrongpha, on Friday credited the dramatic improvement in his game to the influence of his coach Andrew Knott.
The 24-year-old Thai professional made use of the calm morning conditions at the Damai Indah Golf, PIK Course to card a second round 63 to go into the clubhouse tied for the lead on 12-under-par alongside Padraig Harrington.
Khrongpha turned professional in 2010 but struggled to make the step up to Asian Tour level and after a string of disappointing results, teamed up with Knott in 2013.
Since then, he wiry player from Thailand has been in a rich vein of form and finished in the top five twice in the last two weeks.
"Everything in my game was good especially my ball striking. I hit a lot of shots for close range birdies. The longest birdie of the day was on the seventh hole from 30 feet," Thanyakon said from the clubhouse after his round.
"I enjoyed a good run after turning professional in 2010 but after that I didn't do too well because I had no confidence in my swing. Mentally I was not strong enough. Then last year, I worked with Andrew and I've really improved since then," he explained.
Harrington had just completed his 12th hole before play was called off for the day due to inclement weather.
The three-time major winner started his second round with an eagle and reached the turn at five-under for the day.
"I had a nice start. I hit a nice drive and a five iron to about 15 feet for eagle. I birdied the next two as well. It was nice to be four-under after three holes. I didn't play quite solid after that but we'll have to see if I can finish strongly tomorrow," Harrington said.
"The course is playing nicely. There was a bit of wind in the afternoon which made it trickier. As I play more rounds I get to know the course a little better. I have an early wake-up call tomorrow so hopefully I can continue to do well."
