Chinese Taipei’s Shapiyate Mako carded a six-under-par 66 featuring the first hole-in-one of his professional career to open up a one-shot lead after the second round of the US$120,000 HCT ADT Open at Hsin Feng Golf Country Club on Wednesday.

Starting the day tied for 19th after an opening-round 70, Mako climbed 18 places with a composed second-round performance to reach eight-under-par 136. He heads into the final two rounds one stroke clear of Japan’s Nobuaki Oda and Shunichiro Morioka, and fellow Chinese Taipei player Chang Wei-lun, who share second place on seven-under 137.

The highlight of Mako’s round came at the 155-yard par-three eighth, where he holed a nine-iron from 145 yards for the first hole-in-one of his professional career.

“It was my first hole-in-one in a professional tournament,” he said.

The 30-year-old said every aspect of his game contributed to his move into the outright lead, particularly his approach play, which consistently left him with makeable birdie opportunities.

Birdies at the fourth, seventh, 10th and 18th were complemented by the ace at the eighth, while his only blemishes came with bogeys at the opening hole and the sixth.

Mako credited his extensive experience around Hsin Feng Golf Country Club for helping him avoid trouble and plot his way around one of the more demanding layouts on the Asian Development Tour schedule.

“I’ve played this course many, many times, from my amateur days through my professional career,” he said. “I know where you can’t miss it and where the ball needs to be. Today I played very steadily and created a lot of birdie opportunities.”

Oda stayed firmly in contention after posting a two-under-par 68, while Morioka battled to an even-par 70 despite carding five birdies.

The Japanese player admitted the putter prevented him from challenging for the lead after suffering two costly three-putts.

“My driving and iron play were good today, but I couldn’t control my putting,” he said.

Despite the frustrations on the greens, Morioka still produced several highlights, including a chip-in birdie at the ninth, a two-putt birdie after reaching the par-five 14th in two shots, and a five-metre birdie putt at the 15th.

Chang matched Morioka’s even-par 70 to remain one shot off the lead, with the local player continuing to benefit from his familiarity with the course.

Nine players are tied for eighth place on five-under-par 139, including first-round co-leaders Hung Chien-yao and Tawit Polthai, while another five players sit just a shot further back on four-under 140 to leave the tournament finely balanced heading into the third round.

India’s Shaurya Bhattacharya produced the round of the tournament, a superb eight-under-par 64, to climb from five over after the opening round into a tie for 22nd on three-under 141.

After struggling on Tuesday, Bhattacharya said the turnaround came from changing his mindset rather than altering his swing.

“Yesterday I expected too much from myself because I knew it was going to be a scoring week,” he said. “Today I went onto the course with no expectations and that really helped.”

Starting on the back nine, Bhattacharya birdied his second hole to build confidence before taking advantage of the scoring opportunities on the inward half. He missed just one fairway all day, with his only bogey following that miss.

“I drove the ball really well and missed only one fairway, which led to my only bogey,” he said. “The course is demanding off the tee, so tomorrow I’ll just focus on hitting fairways and doing the same things I did today.”

With just three shots separating Mako from the group tied for eighth, another closely contested day is expected when the tournament resumes on Thursday.
