2026 CHAU-SHI Series - GIANT Open

Final Round Press Release

May 30, 2026

The second event of the 2026 CHAU-SHI Series, the GIANT Open, with a total purse of NT$3 million, concluded today (May 30) at Hsinchu Hsin Feng Golf Club. Starting the final round with a six-shot lead, Tsai Kai-jen delivered another steady performance, carding a 4-under-par 68 to maintain his advantage throughout the day. He finished with a four-round total of 19-under-par 269, securing a commanding five-stroke victory and earning the champion’s prize of NT$500,000. It marked his first title of the year.

The victory was his first since winning the Wealthy Family Open at Takangshan Golf Club in Kaohsiung in October 2025 and represented the fourth title of his Taiwan Tour career.

Tsai was the only player in the field to post scores in the 60s in all four rounds, and he held the outright lead after every round of the tournament.

Su Chin-hung fired a 67 in the final round to finish runner-up at 14-under-par 274, earning NT$250,000 in prize money.

Huang Yi-tseng also shot a 68 and finished third at 279. Chan Shih-chang posted a 70 to finish fourth at 281.

Speaking during the awards ceremony, Tsai said that he had previously won the Yeangder Elite Open at Hsin Feng Golf Club three years ago and was delighted to claim another victory at the same venue. He described Hsin Feng Golf Club as his lucky course. The difference this time, he noted, was that he entered the final round as the leader and successfully converted the advantage into victory.

In addition to thanking the title sponsor and tournament organizers, Tsai expressed special gratitude to his sponsors Fenix, Titleist, FootJoy, Golf Gym, his coaches Peter, Brian, and Tsai Ting-hung, as well as his family and friends who have always supported him.

The 27-year-old Tsai has been playing golf for 20 years. In 2021, he won two titles on the ThreeBond Challenge Tour and captured both Rookie of the Year and the ThreeBond Challenge Tour Order of Merit title. In 2023, he claimed two Taiwan Tour victories, including the Nan Pao Open and the Yeangder Elite Open. However, injuries led to a difficult period lasting approximately a year and a half from 2024 through the second half of last year. After fully recovering, he captured his third career title in October last year and now adds a fourth title to his résumé.

Tsai noted after the round that despite beginning the day with a six-shot lead, he knew the chasing players were highly capable and could not be underestimated. He admitted to feeling nervous early in the round, but as his game settled in, he successfully navigated several challenging situations and regained his composure. Throughout the day, he never allowed his opponents an opportunity to overtake him and maintained a lead of approximately four shots.

His final-round scorecard included five birdies and one bogey. Several key shots contributed to the victory. The first came on the opening hole when playing partner Su Chin-hung made a birdie and Tsai immediately responded with a birdie of his own, helping him stay calm. “I didn’t want my opponents to close the gap,” he said.

Another critical moment occurred at the par-4 seventh hole when his approach shot flew too far, finishing behind the green on the left side. His third shot only managed to reach the putting surface, leaving a 30-foot putt, which he remarkably holed to save par.

At the par-5 ninth hole, his tee shot drifted left and even struck a tree. Fortunately, the ball remained in a position that allowed him to attack the green, and he successfully converted the opportunity into a birdie.

At the 172-yard par-3 12th hole, he hit a 46-degree wedge to 12 feet and made the putt for another birdie.

The par-4 13th hole also provided a challenge when his tee shot went left into the rough near the 14th hole. Luckily, he found an opening to attack the green from about 60 yards away. After reaching the edge of the green, he chipped and putted successfully to save par.

Tsai also pointed out that one of the biggest keys to victory this week was his performance on the par-5 holes. Across the tournament’s sixteen par-5s, he recorded twelve birdies and two eagles, gaining a total of sixteen strokes under par. His putting was another major factor. He needed only 29 putts in the final round after totals of 25, 25, and 28 putts over the first three rounds. He added that his long game was more consistent than before and that his short-game execution around the greens was excellent throughout the week.

In addition to continuing to improve his game and compete on the Taiwan Tour, Tsai plans to focus on the two Asian Tour events and three Asian Development Tour events held in Taiwan this year. He also intends to attend Japan Golf Tour qualifying school later in the season and hopes to achieve another breakthrough in his career.

GIANT Heavy Machinery Engineering Co., Ltd. has now served as the title sponsor of a Taiwan PGA Tour event for the third consecutive year. During the awards ceremony, Chairman Chang Lin-kuei said that three years ago he hoped to contribute resources to the development of golf in Taiwan. He expressed satisfaction that his company has now title-sponsored the tournament for three straight years and was pleased to see the players’ performances continue to improve. He also wished for continued growth and success for his company and encouraged everyone to keep striving forward together.

GIANT Heavy Machinery Engineering Co., Ltd. served as the presenting title sponsor, The PGA of Taiwan (TPGA) organized the tournament, and Hsin Feng Golf Club acted as the co-organizer.

The event is one of eight tournaments on this year’s CHAU-SHI Series schedule and the second event of the season. The CHAU-SHI Series also features a special Order of Merit bonus.

The CHAU-SHI Series was established by Mr. Wong Chau-shi, one of the founders of Mercuries Group and its Honorary Chairman. Beginning in 2021, when the number of Taiwan Tour events and total prize money were significantly reduced due to the pandemic, Mr. Wong personally provided title sponsorship for six tournaments, contributing NT$2 million per event for a total of NT$12 million. His support helped establish the foundation of the Taiwan Tour during that difficult period. This year marks the sixth consecutive season that the CHAU-SHI Series has been held under the same sponsorship model. Each tournament receives NT$1.5 million in sponsorship funding, and the 2026 schedule consists of eight tournaments.

Highlights from the final two rounds of the tournament will be broadcast in recorded format on June 9 and June 10 at 4:00 p.m. The broadcasts will be available through TPGA’s Facebook page, YouTube channel, Yahoo Sports, the LINE platform Golfourit, the TPGA official website, VL Sports, and Line Today.
